shock.
During power-on or operation, do not open the front cover of the servo amplifier. You may get an electric
shock.
Do not operate the servo amplifier with the front cover removed. High-voltage terminals and charging area
are exposed and you may get an electric shock.
Except for wiring or periodic inspection, do not remove the front cover even of the servo amplifier if the
power is off. The servo amplifier is charged and you may get an electric shock.
2. To prevent fire, note the following
CAUTION
Install the servo amplifier, servo motor and regenerative resistor on incombustible material. Installing them
directly or close to combustibles will lead to a fire.
Always connect a magnetic contactor (MC) between the main circuit power supply and L1, L2, and L3 of
the servo amplifier, and configure the wiring to be able to shut down the power supply on the side of the
servo amplifier’s power supply. If a magnetic contactor (MC) is not connected, continuous flow of a large
current may cause a fire when the servo amplifier malfunctions.
When a regenerative resistor is used, use an alarm signal to switch main power off. Otherwise, a
regenerative transistor fault or the like may overheat the regenerative resistor, causing a fire.
3. To prevent injury, note the follow
CAUTION
Only the voltage specified in the Instruction Manual should be applied to each terminal, Otherwise, a
burst, damage, etc. may occur.
Connect the terminals correctly to prevent a burst, damage, etc.

1. FUNCTIONS AND CONFIGURATION
1. FUNCTIONS AND CONFIGURATION
1.1 Introduction
The MR-J3- T CC-Link compatible servo amplifier can support the CC-Link communication functions. Up to 42
axes of servo amplifiers can be controlled/monitored from the programmable controller side.
As the servo, it has the function to perform positioning operation by merely setting the position data (target
positions), servo motor speeds, acceleration and deceleration time constants, etc. to point tables as if setting
them in parameters. The servo amplifier is the most appropriate to configure a program-free, simple positioning
system or to simplify a system, for example.
There are 31 points of point tables to be used when 1 station is occupied and 255 points when 2 stations are
occupied.
All servo motors are equipped with an absolute position encoder as standard. An absolute position detection
system can be configured by merely adding a battery to the servo amplifier. Once the home position has been
set, home position return is not required at power on, alarm occurrence, etc.
The MR-J3-T is made easier to use and higher in function by using it with the MR Configurator.
1.1.1 Features of CC-Link communication functions
(1) Fast communication
Fast communication can be made by cyclic transmission of not only bit data but also word data.
(a) The highest communication speed is 10Mbps.
(b) The broadcast polling system ensures as high as 3.9ms to 6.7ms even at the maximum link scan
(10Mbps).
(2) Variable communication speed/distance system
Selection of speed/distance allows use in a wide range of areas from a system requiring high speed to a
system requiring long distance.
(3) System fault prevention (station separating function)
Because of connection in the bus system, any remote or local station that has become faulty due to power-
off or the like does not affect communications with normal remote and local stations.
In addition, use of the two-piece terminal block allows the unit to be changed during data link.
(4) Factory Automation compatible
As the remote device stations of CC-Link, the servo amplifiers share a link system and can be
controlled/monitored with programmable controller user programs.
From the programmable controller side, the running speed, acceleration/deceleration time constant and
other settings of servo motors can be changed/checked and the servo motors started and stopped.

Close mounting is available for the servo amplifier of under 3.5kW for 200V
class and 400W for 100V class.
Leave a large clearance between the top of the servo amplifier and the internal surface of the control
box, and install a cooling fan to prevent the internal temperature of the control box from exceeding the
environmental conditions.
When installing the servo amplifiers closely, leave a clearance of 1mm between the adjacent servo
amplifiers in consideration of mounting tolerances.
In this case, bring the ambient temperature within 0 to 45 (32 to 113 ), or use it at 75% or a smaller
effective load ratio.

(3) Others
When using heat generating equipment such as the regenerative option, install them with full consideration
of heat generation so that the servo amplifier is not affected.
Install the servo amplifier on a perpendicular wall in the correct vertical direction.
2.2 Keep out foreign materials
(1) When installing the unit in a control box, prevent drill chips and wire fragments from entering the servo
amplifier.
(2) Prevent oil, water, metallic dust, etc. from entering the servo amplifier through openings in the control box
or a cooling fan installed on the ceiling.
(3) When installing the control box in a place where there are much toxic gas, dirt and dust, conduct an air
purge (force clean air into the control box from outside to make the internal pressure higher than the
external pressure) to prevent such materials from entering the control box.
2.3 Cable stress
(1) The way of clamping the cable must be fully examined so that flexing stress and cable's own weight stress
are not applied to the cable connection.
(2) For use in any application where the servo motor moves, fix the cables (encoder, power supply, brake) with
having some slack from the connector connection part of the servo motor to avoid putting stress on the
connector connection part. Use the optional encoder cable within the flexing life range. Use the power
supply and brake wiring cables within the flexing life of the cables.
(3) Avoid any probability that the cable sheath might be cut by sharp chips, rubbed by a machine corner or
stamped by workers or vehicles.
(4) For installation on a machine where the servo motor will move, the flexing radius should be made as large
as possible. Refer to section 10.4 for the flexing life.

2.4 Inspection items
WARNING
Before starting maintenance and/or inspection, turn off the power and wait for 15
minutes or more until the charge lamp turns off. Then, confirm that the voltage
between P( ) and N( ) is safe with a voltage tester and others. Otherwise, an
electric shock may occur. In addition, always confirm from the front of the servo
amplifier whether the charge lamp is off or not.
Any person who is involved in inspection should be fully competent to do the work.
Otherwise, you may get an electric shock. For repair and parts replacement,
contact your safes representative.
POINT
Do not test the servo amplifier with a megger (measure insulation resistance),
or it may become faulty.
Do not disassemble and/or repair the equipment on customer side.
It is recommended to make the following checks periodically.
(1) Check for loose terminal block screws. Retighten any loose screws.
(2) Check the cables and the like for scratches and cracks. Perform periodic inspection according to operating
conditions.
2.5 Parts having service lives
The following parts must be changed periodically as listed below. If any part is found faulty, it must be changed
immediately even when it has not yet reached the end of its life, which depends on the operating method and
environmental conditions. For parts replacement, please contact your sales representative.
Part name Life guideline
Smoothing capacitor 10 years
Relay Number of power-on and number of emergency stop
times : 100,000 times
Cooling fan 10,000 to 30,000hours (2 to 3 years)
Servo amplifier
Absolute position battery Refer to section 5.8
(1) Smoothing capacitor
Affected by ripple currents, etc. and deteriorates in characteristic. The life of the capacitor greatly depends
on ambient temperature and operating conditions. The capacitor will reach the end of its life in 10 years of
continuous operation in normal air-conditioned environment.
(2) Relays
Their contacts will wear due to switching currents and contact faults occur. Relays reach the end of their life
when the cumulative number of power-on and emergency stop times is 100,000, which depends on the
power supply capacity.
(3) Servo amplifier cooling fan
The cooling fan bearings reach the end of their life in 10,000 to 30,000 hours. Normally, therefore, the
cooling fan must be changed in a few years of continuous operation as a guideline.
It must also be changed if unusual noise or vibration is found during inspection.

3.3 Functions
3.3.1 Function block diagram
This section explains the transfer of I/O data to/from the servo amplifier in CC-Link, using function blocks.
(1) Between the master station and servo amplifier in the CC-Link system, link refresh is normally performed at
intervals of 3.5 to 18ms (512 points). The link scan time of link refresh changes with the communication
speed. For details, refer to the CC-Link system master/local unit user's manual.
(2) The I/O refresh and master station sequence program are executed asynchronously. Some programmable
controllers allow link scans to be synchronized with programmable controller scans.
(3) The FROM instruction from the buffer memory of the CC-Link system master/local unit is used to read data
from the servo amplifier, and the TO instruction is used to write data. Some programmable controllers allow
automatic refresh to be set to omit the FROM and TO instructions.

Internal torque limit selection Turning RY(n 2)6 OFF makes the torque limit value of
parameter No.PA11 (forward rotation torque limit) parameter
No.PA12 (reverse rotation torque limit) valid, and turning it ON
makes that of parameter No.PC35 (internal torque limit). (Refer
to section 4.6.3)
RY(n 2)6 1
Proportion control When RY(n 2)7 is turned ON, the speed amplifier is switched
from the proportional integral type to the proportional type.
If the servo motor at a stop is rotated even one pulse by an
external factor, it develops torque in an attempt to compensate
for a position shift. When the shaft is locked mechanically after
Movement completion (RXnC) is turned OFF, for example,
turning Proportion control (RY(n 2)7) ON as soon as
Movement completion (RXnC) turns OFF allows control of
unnecessary torque developed in an attempt to compensate for
a position shift.
When the shaft is to be locked for an extended period of time,
turn Internal torque limit selection (RY(n 2)6) ON
simultaneously with Proportion control (RY(n 2)7) to make the
torque not more than the rated torque using Internal torque
limit (parameter No.PC35).

4. SIGNALS AND WIRING
WARNING
Any person who is involved in wiring should be fully competent to do the work.
Before wiring, turn off the power and wait for 15 minutes or more until the charge
lamp turns off. Then, confirm that the voltage between P( ) and N( ) is safe with
a voltage tester and others. Otherwise, an electric shock may occur. In addition,
always confirm from the front of the servo amplifier whether the charge lamp is off
or not.
Ground the servo amplifier and the servo motor securely.
Do not attempt to wire the servo amplifier and servo motor until they have been
installed. Otherwise, you may get an electric shock.
The cables should not be damaged, stressed excessively, loaded heavily, or
pinched. Otherwise, you may get an electric shock.
CAUTION
Wire the equipment correctly and securely. Otherwise, the servo motor may
operate unexpectedly, resulting in injury.
Connect cables to correct terminals to prevent a burst, fault, etc.
Ensure that polarity ( , ) is correct. Otherwise, a burst, damage, etc. may occur.
The surge absorbing diode installed to the DC relay designed for control output
should be fitted in the specified direction. Otherwise, the signal is not output due to
a fault, disabling the forced stop (EMG) and other protective circuits.

4.1 Input power supply circuit
CAUTION
Always connect a magnetic contactor (MC) between the main circuit power supply
and L1, L2, and L3 of the servo amplifier, and configure the wiring to be able to shut
down the power supply on the side of the servo amplifier’s power supply. If a
magnetic contactor (MC) is not connected, continuous flow of a large current may
cause a fire when the servo amplifier malfunctions.
Use the trouble (ALM) to switch power off. Otherwise, a regenerative transistor
fault or the like may overheat the regenerative resistor, causing a fire.
Wire the power supply and main circuit as shown below so that the servo-on (RYn0) turns off as soon as alarm
occurrence is detected and power is shut off.
A no-fuse breaker (NFB) must be used with the input cables of the power supply.

4.3.2 Power-on sequence
(1) Power-on procedure
1) Always wire the power supply as shown in above section 4.1 using the magnetic contactor with the
main circuit power supply (three-phase: L1, L2, L3, single-phase: L1, L2). Configure up an external
sequence to switch off the magnetic contactor as soon as an alarm occurs.
2) Switch on the control circuit power supply L11, L21 simultaneously with the main circuit power supply
or before switching on the main circuit power supply. If the main circuit power supply is not on, the
display shows the corresponding warning. However, by switching on the main circuit power supply,
the warning disappears and the servo amplifier will operate properly.
3) The servo amplifier can accept the servo-on (RYn0) about 1 to 2s after the main circuit power supply
is switched on. Therefore, when servo-on (RYn0) is switched on simultaneously with the main circuit
power supply, the base circuit will switch on in about 1 to 2s, and the ready (RD) will switch on in
further about 5ms, making the servo amplifier ready to operate. (Refer to paragraph (2) in this
section.)
4) When the reset (RY(n+1)A or RY(n+3)A) is switched on, the base circuit is shut off and the servo
motor shaft coasts.

(3) Forced stop
CAUTION Provide an external forced stop circuit to ensure that operation can be stopped and
power switched off immediately.
Make up a circuit that shuts off main circuit power as soon as EMG is turned off at a forced stop. When
EMG is turned off, the dynamic brake is operated to bring the servo motor to a sudden stop. At this time,
the display shows the servo forced stop warning (AE6).
During ordinary operation, do not use the external forced stop (EMG) to alternate stop and run.
The servo amplifier life may be shortened.
Also, if the forward rotation start (RYn1) and reverse rotation start (RYn2) are on or a pulse train is input
during a forced stop, the servo motor will rotate as soon as the warning is reset. During a forced stop,
always shut off the run command. Note also that during a forced stop, RYn1 and RYn2 must be off.

(5) How to insert the cable into Phoenix Contact connector
POINT
Do not use a precision driver because the cable cannot be tightened with
enough torque.
Insertion of cables into Phoenix Contact connector PC4/6-STF-7.62-CRWH or PC4/3-STF-7.62-CRWH is
shown as follows.
Before inserting the cable into the opening, make sure that the screw of the terminal is fully loose. Insert the
core of the cable into the opening and tighten the screw with a flat-blade screwdriver. When the cable is not
tightened enough to the connector, the cable or connector may generate heat because of the poor contact.
(When using a cable of 1.5mm2 or less, two cables may be inserted into one opening.)
Secure the connector to the servo amplifier by tightening the connector screw.
For securing the cable and the connector, use a flat-blade driver with 0.6mm blade edge thickness and
3.5mm diameter (Recommended flat-blade screwdriver: Phoenix Contact SZS 0.6 3.5). Apply 0.5 to 0.6
Nm torque to screw.

4.6 Detailed description of signals (devices)
4.6.1 Forward rotation start reverse rotation start temporary stop/restart
(1) A forward rotation start (RYn1) or a reverse rotation start (RYn2) should make the sequence which can be
used after the main circuit has been established. These signals are invalid if it is switched on before the
main circuit is established.
Normally, it is interlocked with the ready signal (RD).
(2) A start in the servo amplifier is made when a forward rotation start (RYn1) or a reverse rotation start (RYn2)
changes from OFF to ON. The delay time of the servo amplifier's internal processing is max. 3ms. The
delay time of other devices is max. 10ms.

(3) When a programmable controller is used, the ON time of a forward rotation start (RYn1), a reverse rotation
start (RYn2) or temporary start/stop (RYn7) signal should be 6ms or longer to prevent a malfunction.
(4) During operation, the forward rotation start (RYn1) or reverse rotation start (RYn2) is not accepted. The
next operation should always be started after the rough match (RXn2) is output with the rough match output
range set to “0” or after the movement completion (RXnC) is output.

CAUTION
When an alarm has occurred, remove its cause, make sure that the operation
signal is not being input, ensure safety, and reset the alarm before restarting
operation.
As soon as an alarm occurs, turn off Servo-on (RYn0) and power off.
When an alarm occurs in the servo amplifier, the base circuit is shut off and the servo motor is coated to a
stop. Switch off the main circuit power supply in the external sequence. To reset the alarm, switch the control
circuit power supply from off to on, press the "SET" button on the current alarm screen, or turn the reset

servo amplifier and servo motor may become faulty due to temperature rise. Securely remove the
cause of the alarm and also allow about 30 minutes for cooling before resuming operation.
(2) Regenerative alarm
If operation is repeated by switching control circuit power off, then on to reset the regenerative (A30)
alarm after its occurrence, the external regenerative resistor will generate heat, resulting in an
accident.
(3) Instantaneous power failure
Undervoltage (A10) occurs when the input power is in either of the following statuses.
A power failure of the control circuit power supply continues for 60ms or longer and the control
circuit is not completely off.

4.11.1 Safety precautions
CAUTION
Configure the electromagnetic brake operation circuit so that it is activated not only
by the servo amplifier signals but also by an external forced stop signal.
Contacts must be open when
servo-off, when an trouble (ALM)
and when an electromagnetic brake
interlock (MBR).
Circuit must be
opened during
forced stop (EMG).
Electromagnetic brake
SON RA EMG
24VDC
The electromagnetic brake is provided for holding purpose and must not be used
for ordinary braking.
Before performing the operation, be sure to confirm that the electromagnetic brake
operates properly.
POINT
Refer to the Servo Motor Instruction Manual (Vol.2) for specifications such as
the power supply capacity and operation delay time of the electromagnetic
brake.
Note the following when the servo motor equipped with an electromagnetic brake is used.
1) Do not share the 24VDC interface power supply between the interface and electromagnetic brake.
Always use the power supply designed exclusively for the electromagnetic brake.
2) The brake will operate when the power (24VDC) switches off.
3) Switch off the servo-on (RYn0) after the servo motor has stopped.
Using parameter No.PC16 (electromagnetic brake sequence output), set a time delay (Tb) at servo-off from
electromagnetic brake operation to base circuit shut-off as in the timing chart shown in section 4.11.2 in this
section.

4. SIGNALS AND WIRING
4.11.2 Timing charts
(1) Servo-on (RYn0) command (from controller) ON/OFF
Tb [ms] after the servo-on (RYn0) is switched off, the servo lock is released and the servo motor coasts. If
the electromagnetic brake is made valid in the servo lock status, the brake life may be shorter. Therefore,
when using the electromagnetic brake in a vertical lift application or the like, set Tb to about the same as
the electromagnetic brake operation delay time to prevent a drop.

WARNING
Ground the servo amplifier and servo motor securely.
To prevent an electric shock, always connect the protective earth (PE) terminal
(terminal marked ) of the servo amplifier with the protective earth (PE) of the
control box.
The servo amplifier switches the power transistor on-off to supply power to the servo motor. Depending on the
wiring and ground cable routing, the servo amplifier may be affected by the switching noise (due to di/dt and
dv/dt) of the transistor. To prevent such a fault, refer to the following diagram and always ground.
To conform to the EMC Directive, refer to the EMC Installation Guidelines (IB(NA)67310).

5. OPERATION
5.2 Startup
5.2.1 Power on and off procedures
(1) Power-on
Switch power on in the following procedure. Always follow this procedure at power-on.
1) Switch off the servo-on (RYn0).
2) Make sure that the Forward rotation start (RYn1) and Reverse rotation start (RYn2) are off.
3) Switch on the main circuit power supply and control circuit power supply.
When main circuit power/control circuit power is switched on, the servo amplifier display shows
"b01" (if the servo amplifier has the station number of 1).
In the absolute position detection system, first power-on results in the absolute position lost (A25)
alarm and the servo system cannot be switched on.
The alarm can be deactivated then switching power off once and on again.
Also in the absolute position detection system, if power is switched on at the servo motor speed of
3000r/min or higher, position mismatch may occur due to external force or the like. Power must
therefore be switched on when the servo motor is at a stop.
(2) Power-off
1) Make sure that the Forward rotation start (RYn1) and Reverse rotation start (RYn2) are off.
2) Switch off the Servo-on (RYn0).
3) Switch off the main circuit power supply and control circuit power supply.
5.2.2 Stop
In any of the following statuses, the servo amplifier interrupts and stops the operation of the servo motor.
Refer to section 4.11 for the servo motor equipped with an electromagnetic brake.
(a) Servo-on (RYn0) OFF
The base circuit is shut off and the servo motor coasts.
(b) Alarm occurrence
When an alarm occurs, the base circuit is shut off and the dynamic brake is operated to bring the servo
motor to a sudden stop.
(c) Forced stop (EMG) OFF
The base circuit is shut off and the dynamic brake is operated to bring the servo motor to a sudden stop.
The servo forced stop warning (AE6) occurs.
(d) Forward rotation stroke end (LSP), reverse rotation stroke end (LSN) OFF
The droop pulse value is erased and the servo motor is stopped and servo-locked. It can be run in the
opposite direction.

operation mode
In this step, confirm that the servo amplifier and servo motor
operate normally.
With the servo motor disconnected from the machine, use the
test operation mode and check whether the servo motor
correctly rotates at the slowest speed. Refer to section 7.7 and
8.5.7 for the test operation mode.
Test operation of servo motor
alone by commands
In this step, confirm that the servo motor correctly rotates at the
slowest speed under the commands from the command device.
Make sure that the servo motor rotates in the following
procedure.
1) Switch on the Forced stop (EMG) and Servo-on (RYn0).
When the servo amplifier is put in a servo-on status, the
Ready (RD) switches on.
2) Switch on the Forward rotation stroke end (LSP) or Reverse
rotation stroke end (LSN).
3) When the point table is designated to switch on the forward
rotation start (RYn1) or reverse rotation start (RYn2), the
servo motor starts rotating. Give a low speed command at
first and check the rotation direction, etc. of the servo motor.
If the servo motor does not operate in the intended direction,
check the input signal.
Test operation with servo motor
and machine connected
In this step, connect the servo motor with the machine and
confirm that the machine operates normally under the
commands from the command device.
Make sure that the servo motor rotates in the following
procedure.
1) Switch on the Forced stop (EMG) and Servo-on (RYn0).
When the servo amplifier is put in a servo-on status, the
Ready (RD) switches on.
2) Switch on the Forward rotation stroke end (LSP) or Reverse
rotation stroke end (LSN).
3) When the point table is specified from the command device
and the forward rotation start (RYn1) or reverse rotation start
(RYn2) is turned ON, the servo motor starts rotating. Give a
low speed command at first and check the operation
direction, etc. of the machine. If the machine does not
operate in the intended direction, check the input signal. In
the status display, check for any problems of the servo motor
speed, load ratio, etc.

(a) What is automatic continuous operation?
By merely choosing one point table and making a start (RYn1 or RYn2), operation can be performed in
accordance with the point tables having consecutive numbers.
Automatic operation is available in two types: varied speed operation and automatic continuous
positioning operation.
Either type may be selected as follows.

(b) Varied speed operation
Speed during positioning operation can be changed by setting the auxiliary function of the point table.
Use the number of point tables equal to the number of speeds to be set.
By setting "1" to the auxiliary function, operation is performed at the speed set in the next point table
during positioning. The position data valid at this time is the data selected at start and the acceleration
and deceleration time constants of the subsequent point tables are made invalid.
By setting "1" to the auxiliary function of up to point table No.254, operation can be performed at a
maximum of 255 speeds. Set "0" to the auxiliary function of the last point table.
When performing varied speed operation, always set "0" to the dwell. If "1" or more is set, automatic
continuous positioning operation is made valid.
The following table gives a setting example.

the deceleration time constant in the point table being executed. When RYn7 is turned ON again, the
remaining distance is executed.
If the forward/reverse rotation start signal (RYn1 or RYn2) is ignored if it is switched on during a
temporary stop.
The remaining moving distance is cleared when the operation mode is changed from the automatic
mode to the manual mode during a temporary stop.

into the servo amplifier.
In the absolute value command system, Absolute value/incremental value selection (RY(n 2)B) can be
used to select whether the values set to the position data are absolute values or incremental values. The
position data set to RWwn 4/RWwn 5 are handled as absolute values when RY(n 2)B is turned OFF or
as incremental values when it is turned ON. During operation, how the position data will be handled
(absolute values or incremental values) depends on the status of RY(n 2)B when Forward rotation start
(RYn1) is turned ON.
Here, RY(n 2)B is turned OFF since the position data are handled as absolute values.

5.6 Manual home position return mode
5.6.1 Outline of home position return
Home position return is performed to match the command coordinates with the machine coordinates. In the
incremental system, home position return is required every time input power is switched on. In the absolute
position detection system, once home position return is done at the time of installation, the current position is
retained if power is switched off. Hence, home position return is not required when power is switched on again.
This servo amplifier has the home position return methods given in this section. Choose the most appropriate
method for your machine structure and application.
This servo amplifier has the home position return automatic return function which executes home position
return by making an automatic return to a proper position if the machine has stopped beyond or at the
proximity dog. Manual motion by jog operation or the like is not required.
5 - 32
5. OPERATION
(1) Home position return types
Choose the optimum home position return according to the machine type, etc.
Type Home position return method Features
Dog type home position
return
With deceleration started at the front end of a proximity
dog, the position where the first Z-phase signal is given
past the rear end of the dog or a motion has been
made over the home position shift distance starting
from the Z-phase signal is defined as a home position.
General home position return method using a
proximity dog.
Repeatability of home position return is
excellent.
The machine is less burdened.
Used when the width of the proximity dog can
be set greater than the deceleration distance of
the servo motor.
Count type home position
return
With deceleration started at the front end of a proximity
dog, the position where the first Z-phase signal is given
after advancement over the preset moving distance
after the proximity dog or a motion has been made
over the home position shift distance starting from the
Z-phase signal is defined as a home position.
Home position return method using a proximity
dog.
Used when it is desired to minimize the length
of the proximity dog.
Data setting type home
position return An arbitrary position is defined as a home position. No proximity dog required.
Stopper type home
position return
The position where the machine stops when its part is
pressed against a machine stopper is defined as a
home position.
Since the machine part collides with the
machine be fully lowered.
The machine and stopper strength must be
increased.
Home position ignorance
(Servo-on position as
home position)
The position where servo is switched on is defined as
a home position.
Dog type rear end
reference
The position where the axis, which had started
decelerating at the front end of a proximity dog, has
moved the after-proximity dog moving distance and
home position shift distance after it passed the rear
end is defined as a home position.
The Z-phase signal is not needed.
Count type front end
reference
The position where the axis, which had started
decelerating at the front end of a proximity dog, has
moved the after-proximity dog moving distance and
home position shift distance is defined as a home
position.
The Z-phase signal is not needed.
Dog cradle type
The position where the first Z-phase signal is issued
after detection of the proximity dog front end is defined
as a home position.
Dog type first Z-phase
reference
After the proximity dog front end is detected, the
current position moves away from the proximity dog in
the reverse direction. In this movement, the home
position is defined to be where the first Z-phase signal
is issued or the position that is the home position shift
distance away from where the first Z-phase signal is
issued.
Dog type front end
reference The home position is the front end of the proximity dog. The Z-phase signal is not needed.
Dogless Z-phase
reference
The home position is defined to be where the first Z-
phase signal is issued or the position that is the home
position shift distance away from where the first Z-
phase signal is issued.

5.6.3 Count type home position return
In count type home position return, a motion is made over the distance set in parameter No.PC08 (moving
distance after proximity dog) after detection of the proximity dog front end. The position where the first Z-phase
signal is given after that is defined as a home position. Hence, if the proximity dog (DOG) is 10ms or longer,
there is no restriction on the dog length. This home position return method is used when the required proximity
dog length cannot be reserved to use dog type home position return or when the proximity dog (DOG) is
entered electrically from a controller or the like.

5.6.7 Dog type rear end reference home position return
POINT
This home position return method depends on the timing of reading Proximity
dog (DOG) that has detected the rear end of a proximity dog. Hence, if a
home position return is made at the creep speed of 100r/min, an error of
400 pulses will occur in the home position. The error of the home position is
larger as the creep speed is higher.
The position where the axis, which had started decelerating at the front end of a proximity dog, has moved the
after-proximity dog moving distance and home position shift distance after it passed the rear end is defined as
a home position. A home position return that does not depend on the Z-phase signal can be made.

5.6.13 Home position return automatic return function
If the current position is at or beyond the proximity dog in the home position return using the proximity dog, this
function starts home position return after making a return to the position where the home position return can be
made.

start position
Makes an automatic return to a position
before the proximity dog, then executes
home position return at this position.
(2) When the current position is beyond the proximity dog
At a start, a motion is made in the home position return direction and an automatic return is made on
detection of the stroke end (LSP or LSN). The motion stops past the front end of the proximity dog, and
home position return is resumed at that position. If the proximity dog cannot be detected, the motion stops
on detection of the LSP or LSN switch and A90 occurs.

If this function is used when returning to the home position again after performing a manual home position
return after a power-on and deciding the home position, automatic positioning can be carried out to the home
position at high speed. In an absolute position detection system, manual home position return is not required
after power-on.

CAUTION
If an absolute position erase alarm (A25) or an absolute position counter warning
(AE3) has occurred, always perform home position setting again. Not doing so
may cause unexpected operation.
POINT
If the encoder cable is disconnected, absolute position data will be lost in the
following servo motor series. HF-MP, HF-KP, HC-SP, HC-RP, HC-UP, HC-
LP, and HA-LP. After disconnecting the encoder cable, always execute home
position setting and then positioning operation.
When the following parameters are changed, the home position is lost when
turning on the power after the change. Execute the home position return
again when turning on the power.

Parameter No.PA14 (Rotation direction selection)
Parameter No.PC07 (Home position return position data)
This servo amplifier contains a single-axis controller. Also, all servo motor encoders are compatible with an
absolute position detection system. Hence, an absolute position detection system can be configured up by
merely loading an absolute position data back-up battery and setting parameter values.
(1) Restrictions
An absolute position detection system cannot be built under the following conditions.
1) Stroke-less coordinate system, e.g. rotary shaft, infinite positioning.
2) Operation performed in incremental value command type positioning system.

Component Description
Servo amplifier
Servo motor Use standard models.
Battery MR-J3BAT
Encoder cable Use a standard model. (Refer to section 14.1.)
(4) Outline of absolute position detection data communication
For normal operation, as shown below, the encoder consists of a detector designed to detect a position
within one revolution and a cumulative revolution counter designed to detect the number of revolutions.
The absolute position detection system always detects the absolute position of the machine and keeps it
battery-backed, independently of whether the general-purpose programming controller power is on or off.
Therefore, once the home position is defined at the time of machine installation, home position return is not
needed when power is switched on thereafter.
If a power failure or a fault occurs, restoration is easy.

WARNING
Before installing a battery, turn off the main circuit power while keeping the control
circuit power on. Wait for 15 minutes or more until the charge lamp turns off. Then,
confirm that the voltage between P( ) and N( ) is safe with a voltage tester and
others. Otherwise, an electric shock may occur. In addition, always confirm from
the front of the servo amplifier whether the charge lamp is off or not.
POINT
The internal circuits of the servo amplifier may be damaged by static electricity.
Always take the following precautions.
Ground human body and work bench.
Do not touch the conductive areas, such as connector pins and electrical
parts, directly by hand.
Before starting battery changing procedure, make sure that the main circuit
power is switched OFF with the control circuit power ON. When battery is
changed with the control power OFF, the absolute position data is lost.

6. PARAMETERS
6.3.3 S-pattern acceleration/deceleration
In servo operation, linear acceleration/deceleration is usually made. By setting the S-pattern acceleration/
deceleration time constant (parameter No.PC13), a smooth start/stop can be made. When the S-pattern time
constant is set, smooth positioning is executed as shown below. Note that the time equivalent to the S-pattern
time constant setting increases until positioning (RXnC) is complete.

6.3.4 Alarm history clear
The alarm history can be confirmed by using the MR Configurator. The servo amplifier stores one current
alarm and five past alarms from when its power is switched on first. To control alarms which will occur during
operation, clear the alarm history using parameter No.PC18 (alarm history clear) before starting operation.
Clearing the alarm history automatically returns to " 0".
This parameter is made valid by switching power off, then on after setting.

6.3.5 Rough match output
Rough match (RXn2) is output when the command remaining distance reaches the value set in parameter
No.PC11 (rough match output range). The setting range is 0 to 65535 [ 10STM m].

6.3.6 Software limit
A limit stop using a software limit (parameter No.PC31 to PC34) is made as in stroke end operation. When a
motion goes beyond the setting range, the motor is stopped and servo-locked. This function is made valid at
power-on but made invalid during home position return. This function is made invalid when the software limit
setting is the same as the software limit setting. A parameter error (A37) will occur if the software limit
setting is less than the software limit setting.

9.1.2 Adjustment using MR Configurator
This section gives the functions and adjustment that may be performed by using the servo amplifier with the
MR Configurator which operates on a personal computer.
Function Description Adjustment
Machine analyzer With the machine and servo motor coupled,
the characteristic of the mechanical system
can be measured by giving a random
vibration command from the personal
computer to the servo and measuring the
machine response.
You can grasp the machine resonance frequency and
determine the notch frequency of the machine resonance
suppression filter.
You can automatically set the optimum gains in response
to the machine characteristic. This simple adjustment is
suitable for a machine which has large machine resonance
and does not require much settling time.
Gain search Executing gain search under to-and-fro
positioning command measures settling
characteristic while simultaneously changing
gains, and automatically searches for gains
which make settling time shortest.
You can automatically set gains which make positioning
settling time shortest.
Machine simulation Response at positioning settling of a
machine can be simulated from machine
analyzer results on personal computer.
You can optimize gain adjustment and command pattern
on personal computer.

9. GENERAL GAIN ADJUSTMENT
9.2 Auto tuning
9.2.1 Auto tuning mode
The servo amplifier has a real-time auto tuning function which estimates the machine characteristic (load
inertia moment ratio) in real time and automatically sets the optimum gains according to that value. This
function permits ease of gain adjustment of the servo amplifier.
(1) Auto tuning mode 1
The servo amplifier is factory-set to the auto tuning mode 1.
In this mode, the load inertia moment ratio of a machine is always estimated to set the optimum gains
automatically.
The following parameters are automatically adjusted in the auto tuning mode 1.
Parameter No. Abbreviation Name
PB06 GD2 Ratio of load inertia moment to servo motor inertia moment
PB07 PG1 Model loop gain
PB08 PG2 Position loop gain
PB09 VG2 Speed loop gain
PB10 VIC Speed integral compensation
POINT
The auto tuning mode 1 may not be performed properly if the following
conditions are not satisfied.
Time to reach 2000r/min is the acceleration/deceleration time constant of 5s or
less.
Speed is 150r/min or higher.
The ratio of load inertia moment to servo motor inertia moment is 100 times or
less.
The acceleration/deceleration torque is 10% or more of the rated torque.
Under operating conditions which will impose sudden disturbance torque
during acceleration/deceleration or on a machine which is extremely loose,
auto tuning may not function properly, either. In such cases, use the auto
tuning mode 2 or manual mode to make gain adjustment.
(2) Auto tuning mode 2
Use the auto tuning mode 2 when proper gain adjustment cannot be made by auto tuning mode 1. Since
the load inertia moment ratio is not estimated in this mode, set the value of a correct load inertia moment
ratio (parameter No.PB06).
The following parameters are automatically adjusted in the auto tuning mode 2.
Parameter No. Abbreviation Name
PB07 PG1 Model loop gain
PB08 PG2 Position loop gain
PB09 VG2 Speed loop gain

When a servo motor is accelerated/decelerated, the load inertia moment ratio estimation section always
estimates the load inertia moment ratio from the current and speed of the servo motor. The results of
estimation are written to parameter No.PB06 (the ratio of load inertia moment to servo motor). These results
can be confirmed on the status display screen of the MR Configurator section.
If the value of the load inertia moment ratio is already known or if estimation cannot be made properly, chose
the "auto tuning mode 2" (parameter No.PA08: 0002) to stop the estimation of the load inertia moment ratio
(Switch in above diagram turned off), and set the load inertia moment ratio (parameter No.34) manually.
From the preset load inertia moment ratio (parameter No.PB06) value and response level (parameter
No.PA09), the optimum loop gains are automatically set on the basis of the internal gain tale.
The auto tuning results are saved in the EEP-ROM of the servo amplifier every 60 minutes since power-on. At
power-on, auto tuning is performed with the value of each loop gain saved in the EEP-ROM being used as an
initial value.
POINT
If sudden disturbance torque is imposed during operation, the estimation of
the inertia moment ratio may malfunction temporarily. In such a case, choose
the "auto tuning mode 2" (parameter No.PA08: 0002) and set the correct load
inertia moment ratio in parameter No.PB06.
When any of the auto tuning mode 1 and auto tuning mode settings is
changed to the manual mode 2 setting, the current loop gains and load inertia
moment ratio estimation value are saved in the EEP-ROM.

9.2.3 Adjustment procedure by auto tuning
Since auto tuning is made valid before shipment from the factory, simply running the servo motor automatically
sets the optimum gains that match the machine. Merely changing the response level setting value as required

9.2.4 Response level setting in auto tuning mode
Set the response (The first digit of parameter No.PA09) of the whole servo system. As the response level
setting is increased, the track ability and settling time for a command decreases, but a too high response level
will generate vibration. Hence, make setting until desired response is obtained within the vibration-free range.
If the response level setting cannot be increased up to the desired response because of machine resonance
beyond 100Hz, filter tuning mode (parameter No.PB01) or machine resonance suppression filter (parameter
No.PB13 to PB16) may be used to suppress machine resonance. Suppressing machine resonance may allow
the response level setting to increase. Refer to section 10.3 for filter tuning mode and machine resonance
suppression filter.

10. SPECIAL ADJUSTMENT FUNCTIONS
POINT
The functions given in this chapter need not be used generally. Use them if
you are not satisfied with the machine status after making adjustment in the
methods in chapter 9.
If a mechanical system has a natural resonance point, increasing the servo system response level may cause
the mechanical system to produce resonance (vibration or unusual noise) at that resonance frequency.
Using the machine resonance suppression filter and adaptive tuning can suppress the resonance of the
mechanical system.

10.2 Adaptive filter
(1) Function
Adaptive filter (adaptive tuning) is a function in which the servo amplifier detects machine vibration for a
predetermined period of time and sets the filter characteristics automatically to suppress mechanical
system vibration. Since the filter characteristics (frequency, depth) are set automatically, you need not be
conscious of the resonance frequency of a mechanical system.

POINT
The machine resonance frequency which adaptive tuning mode can respond
to is about 100 to 2.25kHz. Adaptive vibration suppression control has no
effect on the resonance frequency outside this range.
Adaptive vibration suppression control may provide no effect on a mechanical
system which has complex resonance characteristics.

10 - 4
10. SPECIAL ADJUSTMENT FUNCTIONS
POINT
"Filter OFF" enables a return to the factory-set initial value.
When adaptive tuning is executed, vibration sound increases as an excitation
signal is forcibly applied for several seconds.
When adaptive tuning is executed, machine resonance is detected for a
maximum of 10 seconds and a filter is generated. After filter generation, the
adaptive tuning mode automatically shifts to the manual mode.
Adaptive tuning generates the optimum filter with the currently set control
gains. If vibration occurs when the response setting is increased, execute
adaptive tuning again.
During adaptive tuning, a filter having the best notch depth at the set control
gain is generated. To allow a filter margin against machine resonance,
increase the notch depth in the manual mode.
10.3 Machine resonance suppression filter
(1) Function
The machine resonance suppression filter is a filter function (notch filter) which decreases the gain of the
specific frequency to suppress the resonance of the mechanical system. You can set the gain decreasing
frequency (notch frequency), gain decreasing depth and width.

You can use the machine resonance suppression filter 1 (parameter No.PB13, PB14) and machine

frequencies. Execution of adaptive tuning in the filter tuning mode automatically adjusts the machine
resonance suppression filter. When adaptive tuning is ON, the adaptive tuning mode shifts to the manual
mode after the predetermined period of time. The manual mode enables manual setting using the machine
resonance suppression filter 1.

(parameter No.PB13, PB14)
When you have made adaptive filter tuning mode (parameter No.PB01) "manual mode", set up the
machine resonance suppression filter 1 becomes effective.
POINT
The machine resonance suppression filter is a delay factor for the servo
system. Hence, vibration may increase if you set a wrong resonance
frequency or a too deep notch.
If the frequency of machine resonance is unknown, decrease the notch
frequency from higher to lower ones in order. The optimum notch frequency is
set at the point where vibration is minimal.
A deeper notch has a higher effect on machine resonance suppression but
increases a phase delay and may increase vibration.
A deeper notch has a higher effect on machine resonance suppression but
increases a phase delay and may increase vibration.
The machine characteristic can be grasped beforehand by the machine
analyzer on the MR Configurator. This allows the required notch frequency
and depth to be determined.

When the advanced vibration suppression control (vibration suppression control tuning mode parameter

In the vibration suppression control tuning mode, this mode shifts to the manual mode after operation is
performed the predetermined number of times. The manual mode enables manual setting using the
vibration suppression control vibration frequency setting (parameter No.PB19) and vibration suppression

POINT
The function is made valid when the auto tuning mode (parameter No.PA08)
is the auto tuning mode 2 ("0002") or manual mode ("0003").
The machine resonance frequency supported in the vibration suppression
control tuning mode is 1.0Hz to 100.0Hz. The function is not effective for
vibration outside this range.
Stop the motor before changing the vibration suppression control-related
parameters (parameter No.PB02, PB19, PB20, PB33, PB34). A failure to do
so will cause a shock.
For positioning operation during execution of vibration suppression control
tuning, provide a stop time to ensure a stop after full vibration damping.
Vibration suppression control tuning may not make normal estimation if the
residual vibration at the motor side is small.
Vibration suppression control tuning sets the optimum parameter with the
currently set control gains. When the response setting is increased, set
vibration suppression control tuning again.

This function can change the gains. You can change between gains during rotation and gains during stop or
can use an input device to change gains during operation.
10.6.1 Applications
This function is used when.
(1) You want to increase the gains during servo lock but decrease the gains to reduce noise during rotation.
(2) You want to increase the gains during settling to shorten the stop settling time.
(3) You want to change the gains using an input device to ensure stability of the servo system since the load
inertia moment ratio varies greatly during a stop (e.g. a large load is mounted on a carrier).

13. CHARACTERISTICS
13. CHARACTERISTICS
13.1 Overload protection characteristics
An electronic thermal relay is built in the servo amplifier to protect the servo motor and servo amplifier from
overloads. Overload 1 alarm (A50) occurs if overload operation performed is above the electronic thermal relay
protection curve shown in any of Figs 13.1. Overload 2 alarm (A51) occurs if the maximum current flew
continuously for several seconds due to machine collision, etc. Use the equipment on the left-hand side area of
the continuous or broken line in the graph.
In a machine like the one for vertical lift application where unbalanced torque will be produced, it is
recommended to use the machine so that the unbalanced torque is 70% or less of the rated torque.
When you carry out adhesion mounting of the servo amplifier, make circumference temperature into 0 to 45

Note. If operation that generates torque more than 100% of the rating is performed with an abnormally high frequency in a servo motor
stop status (servo lock status) or in a 30r/min or less low-speed operation status, the servo amplifier may fail even when the
electronic thermal relay protection is not activated.

13.2 Power supply equipment capacity and generated loss
(1) Amount of heat generated by the servo amplifier
Table 13.1 indicates servo amplifiers' power supply capacities and losses generated under rated load. For
thermal design of an enclosure, use the values in Table 13.1 in consideration for the worst operating
conditions. The actual amount of generated heat will be intermediate between values at rated torque and
servo off according to the duty used during operation. When the servo motor is run at less than the
maximum speed, the power supply capacity will be smaller than the value in the table, but the servo
amplifier's generated heat will not change.

13 CHARACTERISTICS
(2) Heat dissipation area for enclosed servo amplifier
The enclosed control box (hereafter called the control box) which will contain the servo amplifier should be
designed to ensure that its temperature rise is within 10 ( 50 ) at the ambient temperature of 40
(104 ). (With a 5 (41 ) safety margin, the system should operate within a maximum 55 (131 ) limit.)
The necessary enclosure heat dissipation area can be calculated by Equation 13.1.
P
AKT
............................................................................................................................................. (13.1)
where, A : Heat dissipation area [m2]
P : Loss generated in the control box [W]
T : Difference between internal and ambient temperatures [ ]
K : Heat dissipation coefficient [5 to 6]
When calculating the heat dissipation area with Equation 13.1, assume that P is the sum of all losses
generated in the enclosure. Refer to Table 13.1 for heat generated by the servo amplifier. "A" indicates the
effective area for heat dissipation, but if the enclosure is directly installed on an insulated wall, that extra
amount must be added to the enclosure's surface area.
The required heat dissipation area will vary wit the conditions in the enclosure. If convection in the
enclosure is poor and heat builds up, effective heat dissipation will not be possible. Therefore, arrangement
of the equipment in the enclosure and the use of a cooling fan should be considered.
Table 13.1 lists the enclosure dissipation area for each servo amplifier when the servo amplifier is operated
at the ambient temperature of 40 (104 ) under rated load.
(Outside) (Inside)
Air flow
Fig. 13.2 Temperature distribution in enclosure
When air flows along the outer wall of the enclosure, effective heat exchange will be possible, because the
temperature slope inside and outside the enclosure will be steeper.

13.3 Dynamic brake characteristics
13.3.1 Dynamic brake operation
(1) Calculation of coasting distance
Fig. 13.3 shows the pattern in which the servo motor comes to a stop when the dynamic brake is operated.
Use Equation 13.2 to calculate an approximate coasting distance to a stop. The dynamic brake time
constant varies with the servo motor and machine operation speeds. (Refer to (2)(a), (b) in this section.)

For 7kW or less servo, there is internal relay delay time of about 30ms. For 11k to 22kW servo,
there is delay time of about 100ms caused by a delay of the external relay and a delay of the
magnetic contactor built in the external dynamic brake.

13.3.2 The dynamic brake at the load inertia moment
Use the dynamic brake under the load inertia moment ratio indicated in the following table. If the load inertia
moment is higher than this value, the built-in dynamic brake may burn. If there is a possibility that the load
inertia moment may exceed the value, contact Mitsubishi.
The values of the load inertia moment ratio in the table are the values at the maximum rotation speed of the
servo motor.

WARNING
Before connecting any option or peripheral equipment, turn off the power and wait
for 15 minutes or more until the charge lamp turns off. Then, confirm that the
voltage between P( ) and N( ) is safe with a voltage tester and others.
Otherwise, an electric shock may occur. In addition, always confirm from the front
of the servo amplifier whether the charge lamp is off or not.
CAUTION Use the specified auxiliary equipment and options. Unspecified ones may lead to a
fault or fire.

POINT
Protective structure indicated for cables and connecters is for a cable or
connector alone. When the cables and connectors are used to connect the
servo amplifier and servo motor, and if protective structures of the servo
amplifier and servo motor are lower than that of the cable and connector,
specifications of the servo amplifier and servo motor apply.
As the cables and connectors used with this servo, purchase the options indicated in this section.

When using the regenerative resistors supplied to the servo amplifier, the specified number of resistors
(4 or 5 resistors) must be connected in series. If they are connected in parallel or in less than the
specified number, the servo amplifier may become faulty and/or the regenerative resistors burn. Install
the resistors at intervals of about 70mm. Cooling the resistors with two cooling fans (92 92, minimum
air flow : 1.0m3) improves the regeneration capability. In this case, set " FA" in parameter No.PA02.

Note. The number of resistors connected in series depends on the resistor type. The thermal sensor is not mounted on the
attached regenerative resistor. An abnormal heating of resistor may be generated at a regenerative circuit failure. Install a
thermal sensor near the resistor and establish a protective circuit to shut off the main circuit power supply when abnormal
heating occurs. The detection level of the thermal sensor varies according to the settings of the resistor. Set the thermal
sensor in the most appropriate position on your design basis or use the thermal sensor built-in regenerative option (MR-

14.3 FR-BU2-(H) brake unit
POINT
Use a 200V class brake unit and a resistor unit with a 200V class servo
amplifier, and a 400V class brake unit and a resistor unit with a 400V class
servo amplifier. Combination of different voltage class units and servo
amplifier cannot be used.
Install a brake unit and a resistor unit on a flat surface vertically. When the
unit is installed horizontally or diagonally, the heat dissipation effect
diminishes.
Temperature of the resistor unit case rises to higher than 100 . Keep cables
and flammable materials away from the case.
Ambient temperature condition of the brake unit is between 10 (14 ) and
50 (122 ). Note that the condition is different from the ambient
temperature condition of the servo amplifier (between 0 (32 ) and 55
(131 )).
Configure the circuit to shut down the power-supply with the alarm output of
the brake unit and resistor unit under abnormal condition.
Use the brake unit with a combination indicated in section 14.3.1.
For executing a continuous regenerative operation, use FR-RC-(H) power
regeneration converter or FR-CV-(H) power regeneration common converter.
Brake unit and regenerative options (Regenerative resistor) cannot be used
simultaneously.
Connect the brake unit to the bus of the servo amplifier. As compared to the MR-RB regenerative option, the
brake unit can return larger power. Use the brake unit when the regenerative option cannot provide sufficient
regenerative capability.
When using the brake unit, set the parameter No.PA02 of the servo amplifier to " 01".
When using the brake unit, always refer to the FR-BU2-(H) Brake Unit Instruction Manual.

14.5 Power regeneration common converter
POINT
Use the FR-CV for the servo amplifier of 200V class and the FR-CV-H for that
of 400V class.
For details of the power regeneration common converter FR-CV-(H), refer to
the FR-CV-(H) Installation Guide (IB(NA)0600075).
Do not supply power to the main circuit power supply terminals (L1, L2, L3) of
the servo amplifier. Doing so will fail the servo amplifier and FR-CV-(H).
Connect the DC power supply between the FR-CV-(H) and servo amplifier
with correct polarity. Connection with incorrect polarity will fail the FR-CV-(H)
and servo amplifier.
Two or more FR-CV-(H)'s cannot be installed to improve regeneration
capability. Two or more FR-CV-(H)'s cannot be connected to the same DC
power supply line.
When using the power regeneration common converter, set parameter No.PA02 to " 01".

14.6 External dynamic brake
POINT
Configure up a sequence which switches off the contact of the brake unit after
(or as soon as) it has turned off the servo on signal at a power failure or
failure.
For the braking time taken when the dynamic brake is operated, refer to
section 13.3.
The brake unit is rated for a short duration. Do not use it for high duty.
When using the 400V class dynamic brake, the power supply voltage is
restricted to 1-phase 380VAC to 463VAC (50Hz/60Hz).
(1) Selection of dynamic brake
The dynamic brake is designed to bring the servo motor to a sudden stop when a power failure occurs
or the protective circuit is activated, and is built in the 7kW or less servo amplifier. Since it is not built
in the 11kW or more servo amplifier, purchase it separately if required. Assign the dynamic brake interlock
(DB) to any of CN6-14, CN6-15, and CN6-16 pins in parameter No.PD09, PD10 or PD11.

14.7 Battery MR-J3BAT
POINT
The revision (Edition 44) of the Dangerous Goods Rule of the International Air
Transport Association (IATA) went into effect on January 1, 2003 and was
enforced immediately. In this rule, "provisions of the lithium and lithium ion
batteries" were revised to tighten the restrictions on the air transportation of
batteries. However, since this battery is non-dangerous goods (non-Class 9),
air transportation of 24 or less batteries is outside the range of the
restrictions. Air transportation of more than 24 batteries requires packing
compliant with the Packing Standard 903. When a self-certificate is necessary
for battery safety tests, contact our branch or representative. For more
information, consult our branch or representative. (As of Jun, 2008).
(1) Purpose of use for MR-J3BAT
This battery is used to construct an absolute position detection system. Refer to section 14.3 for the fitting
method, etc.
(2) Year and month when MR-J3BAT is manufactured
The year and month when MR-J3BAT is manufactured are written down in Serial No. on the rating plate of
the battery back face.
The year and month of manufacture are indicated by the last one digit of the year and 1 to 9, X(10), Y(11),
Z(12).
For October 2004, the Serial No. is like, "SERIAL 4X ".

14.8 Heat sink outside mounting attachment (MR-J3ACN)
Use the heat sink outside mounting attachment to mount the heat generation area of the servo amplifier in the
outside of the control box to dissipate servo amplifier-generated heat to the outside of the box and reduce the
amount of heat generated in the box, thereby allowing a compact control box to be designed.
In the control box, machine a hole having the panel cut dimensions, fit the heat sink outside mounting
attachment to the servo amplifier with the fitting screws (4 screws supplied), and install the servo amplifier to
the control box.
The environment outside the control box when using the heat sink outside mounting attachment should be
within the range of the servo amplifier operating environment conditions.
The heat sink outside mounting attachment of MR-J3ACN can be used for MR-J3-11KT(4) to MR-J3-22KT(4).

14.11 Power factor improving DC reactor
POINT
For the 100V power supply type (MR-J3- T1), the power factor improving DC
reactor cannot be used.
The power factor improving DC reactor increases the form factor of the servo amplifier's input current to
improve the power factor. It can decrease the power supply capacity. As compared to the power factor
improving AC reactor (FR-BAL), it can decrease the loss. The input power factor is improved to about 95%.
It is also effective to reduce the input side harmonics.
When connecting the power factor improving DC reactor to the servo amplifier, always disconnect P1 and P2
(For 11kW or more, disconnect P1 and P). If it remains connected, the effect of the power factor improving DC
reactor is not produced.
When used, the power factor improving DC reactor generates heat. To release heat, therefore, leave a 10cm or
more clearance at each of the top and bottom, and a 5cm or more clearance on each side.

14.12 Power factor improving reactors
The power factor improving reactors improve the phase factor by increasing the form factor of servo amplifier's
input current.
It can reduce the power capacity.
The input power factor is improved to be about 90%. For use with a 1-phase power supply, it may be slightly
lower than 90%.
In addition, it reduces the higher harmonic of input side.
When using power factor improving reactors for two servo amplifiers or more, be sure to connect a power factor
improving reactor to each servo amplifier.
If using only one power factor improving reactor, enough improvement effect of phase factor cannot be
obtained unless all servo amplifiers are operated.

14.15 Noise reduction techniques
Noises are classified into external noises which enter the servo amplifier to cause it to malfunction and those
radiated by the servo amplifier to cause peripheral devices to malfunction. Since the servo amplifier is an
electronic device which handles small signals, the following general noise reduction techniques are required.
Also, the servo amplifier can be a source of noise as its outputs are chopped by high carrier frequencies. If
peripheral devices malfunction due to noises produced by the servo amplifier, noise suppression measures
must be taken. The measures will vary slightly with the routes of noise transmission.
(1) Noise reduction techniques
(a) General reduction techniques
Avoid laying power lines (input and output cables) and signal cables side by side or do not bundle
them together. Separate power lines from signal cables.
Use shielded, twisted pair cables for connection with the encoder and for control signal transmission,
and connect the shield to the SD terminal.
Ground the servo amplifier, servo motor, etc. together at one point (refer to section 4.12).
(b) Reduction techniques for external noises that cause the servo amplifier to malfunction
If there are noise sources (such as a magnetic contactor, an electromagnetic brake, and many relays
which make a large amount of noise) near the servo amplifier and the servo amplifier may malfunction,
the following countermeasures are required.
Provide surge absorbers on the noise sources to suppress noises.
Attach data line filters to the signal cables.
Ground the shields of the encoder connecting cable and the control signal cables with cable clamp
fittings.
Although a surge absorber is built into the servo amplifier, to protect the servo amplifier and other
equipment against large exogenous noise and lightning surge, attaching a varistor to the power input
section of the equipment is recommended.

(c) Techniques for noises radiated by the servo amplifier that cause peripheral devices to malfunction
Noises produced by the servo amplifier are classified into those radiated from the cables connected to
the servo amplifier and its main circuits (input and output circuits), those induced electromagnetically or
statically by the signal cables of the peripheral devices located near the main circuit cables, and those
transmitted through the power supply cables.

Noise transmission route Suppression techniques
1) 2) 3)
When measuring instruments, receivers, sensors, etc. which handle weak signals and may malfunction
due to noise and/or their signal cables are contained in a control box together with the servo amplifier or
run near the servo amplifier, such devices may malfunction due to noises transmitted through the air. The
following techniques are required.
1. Provide maximum clearance between easily affected devices and the servo amplifier.
2. Provide maximum clearance between easily affected signal cables and the I/O cables of the servo
amplifier.
3. Avoid laying the power lines (Input cables of the servo amplifier) and signal cables side by side or
bundling them together.
4. Insert a line noise filter to the I/O cables or a radio noise filter on the input line.
5. Use shielded wires for signal and power cables or put cables in separate metal conduits.
4) 5) 6)
When the power lines and the signal cables are laid side by side or bundled together, magnetic
induction noise and static induction noise will be transmitted through the signal cables and malfunction
may occur. The following techniques are required.
1. Provide maximum clearance between easily affected devices and the servo amplifier.
2. Provide maximum clearance between easily affected signal cables and the I/O cables of the servo
amplifier.
3. Avoid laying the power lines (I/O cables of the servo amplifier) and signal cables side by side or
bundling them together.
4. Use shielded wires for signal and power cables or put the cables in separate metal conduits.
7)
When the power supply of peripheral devices is connected to the power supply of the servo amplifier
system, noises produced by the servo amplifier may be transmitted back through the power supply
cable and the devices may malfunction. The following techniques are required.
1. Insert the radio noise filter (FR-BIF) on the power cables (Input cables) of the servo amplifier.
2. Insert the line noise filter (FR-BSF01 FR-BLF) on the power cables of the servo amplifier.
8)
When the cables of peripheral devices are connected to the servo amplifier to make a closed loop
circuit, leakage current may flow to malfunction the peripheral devices. If so, malfunction may be
prevented by disconnecting the grounding cable of the peripheral device.
(2) Noise reduction products
(a) Data line filter (Recommended)
Noise can be prevented by installing a data line filter onto the encoder cable, etc.
For example, the ZCAT3035-1330 of TDK and the ESD-SR-25 of NEC TOKIN make are available as
data line filters.
As a reference example, the impedance specifications of the ZCAT3035-1330 (TDK) are indicated

Use the line noise filters for wires of the main power supply
(L1L2 L3) and of the motor power supply (U VW). Pass
each of the 3-phase wires through the line noise filter an equal
number of times in the same direction. For the main power supply,
the effect of the filter rises as the number of passes increases, but
generally four passes would be appropriate. For the motor power
supply, passes must be four times or less. Do not pass the
grounding (earth) wire through the filter, or the effect of the filter
will drop. Wind the wires by passing through the filter to satisfy the
required number of passes as shown in Example 1. If the wires
are too thick to wind, use two or more filters to have the required
number of passes as shown in Example 2. Place the line noise
filters as close to the servo amplifier as possible for their best
performance.

14.16 Leakage current breaker
(1) Selection method
High-frequency chopper currents controlled by pulse width modulation flow in the AC servo circuits.
Leakage currents containing harmonic contents are larger than those of the motor which is run with a
commercial power supply.
Select a leakage current breaker according to the following formula, and ground the servo amplifier, servo
motor, etc. securely.
Make the input and output cables as short as possible, and also make the grounding cable as long as
possible (about 30cm) to minimize leakage currents.

15.2.1 Communication overview
This servo amplifier is designed to send a reply on receipt of an instruction. The device which gives this
instruction (e.g. personal computer) is called a master station and the device which sends a reply in response
to the instruction (servo amplifier) is called a slave station. When fetching data successively, the master station
repeatedly commands the slave station to send data.

15.2.2 Parameter setting
When the USB/RS-422 communication function is used to operate the servo, set the communication
specifications of the servo amplifier in the corresponding parameters.
After setting the values of these parameters, they are made valid by switching power off once, then on again.
(1) Serial communication baud rate
Choose the communication speed. Match this value to the communication speed of the sending end
(master station).
Communication baud rate

(2) RS-422 communication response delay time
Set the time from when the servo amplifier (slave station) receives communication data to when it sends
back data. Set "0" to send back data in less than 800 s or "1" to send back data in 800 s or more.
Parameter No.PC21
RS-422 communication response delay time
0: Invalid
1: Valid, reply sent in 800 s or more
(3) Station number setting
Set the station number of the servo amplifier in parameter No.PC20. The setting range is station 0 to 31.

15. COMMUNICATION FUNCTION
15.3 Protocol
15.3.1 Transmission data configuration
Since up to 32 axes may be connected to the bus, add a station number or group to the command, data No.,
etc. to determine the destination servo amplifier of data communication. Set the station number to each servo
amplifier using the parameter and set the group to each station using the communication command.
Transmission data is valid for the servo amplifier of the specified station number or group.
When "*" is set as the station number added to the transmission data, the transmission data is made valid for
all servo amplifiers connected. However, when return data is required from the servo amplifier in response to
the transmission data, set "0" to the station number of the servo amplifier which must provide the return data.

15.3.5 Time-out operation
The master station transmits EOT when the slave station does not start reply operation (STX is not received)
300ms after the master station has ended communication operation. 100ms after that, the master station
retransmits the message. Time-out occurs if the slave station does not answer after the master station has
performed the above operation three times. (Communication error)

15.3.6 Retry operation
When a fault occurs in communication between the master and slave stations, the error code in the response
data from the slave station is a negative response code ([B] to [F], [b] to [f]). In this case, the master station
retransmits the message which was sent at the occurrence of the fault (Retry operation). A communication
error occurs if the above operation is repeated and results in the error three or more consecutive times.

Similarly, when the master station detects a fault (e.g. checksum, parity) in the response data from the slave
station, the master station retransmits the message which was sent at the occurrence of the fault. A
communication error occurs if the retry operation is performed three times.

15. COMMUNICATION FUNCTION
15.3.7 Initialization
After the slave station is switched on, it cannot reply to communication until the internal initialization processing
terminates. Hence, at power-on, ordinary communication should be started after.
(1) 1s or more time has elapsed after the slave station is switched on; and
(2) Making sure that normal communication can be made by reading the parameter or other data which does
not pose any safety problems.

15.5 Detailed explanations of commands
15.5.1 Data processing
When the master station transmits a command data No. or a command data No. data to a slave station,
the servo amplifier returns a reply or data according to the purpose.
When numerical values are represented in these send data and receive data, they are represented in decimal,
hexadecimal, etc.
Therefore, data must be processed according to the application.
Since whether data must be processed or not and how to process data depend on the monitoring, parameters,
etc., follow the detailed explanation of the corresponding command.
The following methods are how to process send and receive data when reading and writing data.
(1) Processing the read data
When the display type is 0, the eight-character data is converted from hexadecimal to decimal and a
decimal point is placed according to the decimal point position information.
When the display type is 1, the eight-character data is used unchanged.
The following example indicates how to process the receive data "003000000929" given to show.
The receive data is as follows.
00
Data 32-bit length (hexadecimal representation)
(Data conversion is required as indicated in the display type
)
Display type
0: Data must be converted into decimal.
1: Data is used unchanged in hexadecimal.
Decimal point position
0: No decimal point
1: First least significant digit (normally not used)
2: Second least significant digit
3: Third least significant digit
4: Forth least significant digit
5: Fifth least significant digit
6: Sixth least significant digit
3000000929
Since the display type is "0" in this case, the hexadecimal data is converted into decimal.
00000929H 2345
As the decimal point position is "3", a decimal point is placed in the third least significant digit.
Hence, "23.45" is displayed.
15 - 18
15. COMMUNICATION FUNCTION
(2) Writing the processed data
When the data to be written is handled as decimal, the decimal point position must be specified. If it is not
specified, the data cannot be written. When the data is handled as hexadecimal, specify "0" as the decimal
point position.
The data to be sent is the following value.
0
Data is transferred in hexadecimal.
Decimal point position
0: No decimal point
1: First least significant digit
2: Second least significant digit
3: Third least significant digit
4: Forth least significant digit
5: Fifth least significant digit
By way of example, here is described how to process the set data when a value of "15.5" is sent.
Since the decimal point position is the second digit, the decimal point position data is "2".
As the data to be sent is hexadecimal, the decimal data is converted into hexadecimal.
155 9B
Hence, "0200009B" is transmitted.

If setting values need to be changed with a high frequency (i.e. one time or
more per one hour), write the setting values to the RAM, not the EEP-ROM.
The EEP-ROM has a limitation in the number of write times and exceeding
this limitation causes the servo amplifier to malfunction. Note that the number
of write times to the EEP-ROM is limited to approximately 100, 000.
Write the parameter setting into EEP-ROM of the servo amplifier. Specify the parameter group in advance
(refer to (1) in this section).
Write the value within the setting enabled range. For the setting enabled range, refer to chapter 6 or read
the setting range by performing operation in (3) in this section.
Transmit command [8][4], the data No. , and the set data.
The data No. is expressed in hexadecimal. The decimal equivalent of the data No. value corresponds to the
parameter number.
When the data to be written is handled as decimal, the decimal point position must be specified. If it is not
specified, data cannot be written. When the data is handled as hexadecimal, specify 0 as the decimal point
position.
Write the data after making sure that it is within the upper/lower limit value range.
Read the parameter data to be written, confirm the decimal point position, and create transmission data to
prevent error occurrence. On completion of write, read the same parameter data to verify that data has
been written correctly.
Command Data No. Set data
[8][4] [0][1] to
[F][F]
See below.
Data is transferred in hexadecimal.
Decimal point position
0: No decimal point
1: Lower first digit
2: Lower second digit
3: Lower third digit
4: Lower forth digit
5: Lower fifth digit
Write mode
0: Write to EEP-ROM
3: Write to RAM
When the parameter data is changed frequently through communication,
set "3" to the write mode to change only the RAM data in the servo amplifier.
When changing data frequently (once or more within one hour),
do not write it to the EEP-ROM.

15. COMMUNICATION FUNCTION
15.5.8 Test operation mode
POINT
The test operation mode is used to confirm operation. Do not use it for actual
operation.
If communication stops for longer than 0.5s during test operation, the servo
amplifier decelerates to a stop, resulting in servo lock. To prevent this,
continue communication all the time, e.g. monitor the status display.
Even during operation, the servo amplifier can be put in the test operation
mode.
In this case, as soon as the test operation mode is selected, the base circuit
is shut off, coasting the servo amplifier.
(1) Preparation and cancel of test operation mode

to section 16.3.2 (3))
RY(n 2)6
Proportion control When RY(n 2)7 is turned ON, the speed amplifier is switched
from the proportional integral type to the proportional type.
If the servo motor at a stop is rotated even one pulse by an
external factor, it develops torque in an attempt to compensate
for a position shift. When the shaft is locked mechanically after
Movement completion (RXnC) is turned OFF, for example,
turning Proportion control (RY(n 2)7) ON as soon as
Movement completion (RXnC) turns OFF allows control of
unnecessary torque developed in an attempt to compensate for
a position shift.
When the shaft is to be locked for an extended period of time,
turn Internal torque limit selection (RY(n 2)6) ON
simultaneously with Proportion control (RY(n 2)7) to make the
torque not more than the rated torque using Internal torque
limit (parameter No.PC35).

16.3.2 Detailed description of signals (devices)
(1) Forward rotation start reverse rotation start temporary stop/restart
(a) A start (RYn1) should make the sequence which can be used after the main circuit has been
established. These signals are invalid if it is switched on before the main circuit is established.
Normally, it is interlocked with the ready signal (RD).
(b) A start in the servo amplifier is made when a start (RYn1) changes from OFF to ON. The delay time of
the servo amplifier's internal processing is max. 3ms. The delay time of other devices is max. 10ms.
(c) When a programmable controller is used, the ON time of a start (RYn1), should be 6ms or longer to
prevent a malfunction.
(d) During operation, the start (RYn1) is not accepted. The next operation should always be started after
the rough match (RXn2) is output with the rough match output range set to “0” or after the movement
completion (RXnC) is output.
(2) Movement completion rough match in position
POINT
If an alarm cause, etc. are removed and servo-on occurs after a stop is made
by servo-off, alarm occurrence or Forced stop (EMG) ON during automatic
operation, Movement completion (MEND), Rough-match, (CPO) and In
position (INP) are turned on. To resume operation, confirm the current
position and the selected point table No. for preventing unexpected operation.
(a) Movement completion
The following timing charts show the output timing relationships between the position command
generated in the servo amplifier and the movement completion (RYnC). This timing can be changed

16.5 Startup
16.5.1 Power on and off procedures
(1) Power-on
Switch power on in the following procedure. Always follow this procedure at power-on.
1) Switch off the servo-on (RYn0).
2) Make sure that the start (RYn1) is off.
3) Switch on the main circuit power supply and control circuit power supply.
When main circuit power/control circuit power is switched on, the servo amplifier display shows "b01"
(if the servo amplifier has the station number of 1).
In the absolute position detection system, first power-on results in the absolute position lost (A25)
alarm and the servo system cannot be switched on.
The alarm can be deactivated then switching power off once and on again.
Also in the absolute position detection system, if power is switched on at the servo motor speed of
3000r/min or higher, position mismatch may occur due to external force or the like. Power must
therefore be switched on when the servo motor is at a stop.
(2) Power-off
1) Make sure that the start (RYn1) is off.
2) Switch off the Servo-on (RYn0).
3) Switch off the main circuit power supply and control circuit power supply.

In any of the following statuses, the servo amplifier interrupts and stops the operation of the servo motor.
Refer to section 4.11 for the servo motor equipped with an electromagnetic brake.
(a) Servo-on (RYn0) OFF
The base circuit is shut off and the servo motor coasts.
(b) Alarm occurrence
When an alarm occurs, the base circuit is shut off and the dynamic brake is operated to bring the servo
motor to a sudden stop.
(c) Forced stop (EMG) OFF
The base circuit is shut off and the dynamic brake is operated to bring the servo motor to a sudden stop.
The servo forced stop warning (AE6) occurs.
(d) Forward rotation stroke end (LSP), reverse rotation stroke end (LSN) OFF
The droop pulse value is erased and the servo motor is stopped and servo-locked. It can be run in the
opposite direction.

16.7 Automatic operation mode
POINT
In the absolute position detection system, the following restriction condition
applies for the number of gears on machine-side (parameter No.PA06 CMX)
and servo motor speed (N).
When CMX 2000, N 3076.7 r/min
When CMX 2000, N 3276.7–CMX r/min
When the servo motor is operated at servo motor speed higher than the limit
value, the absolute position counter warning (AE3) occurs.
16.7.1 What is automatic operation mode?
(1) Concept of indexer
Select the station, which is dividing the circumference (360 degrees) of the machine side into up to 255,
using 8-bit device of the next station selection 1 to 8 (RYnA to RYnE, and RY(n 2)3 to RY(n 2)5), and

(2) Rotation direction
There are two types of operation methods: Rotation direction specifying indexer, which is to always rotate in
the fixed direction and execute positioning to a station, and Shortest rotating indexer, which is to
automatically change the rotation direction for the shortest distance and execute positioning to a station.

16.9 Home position return mode
16.9.1 Outline of home position return
Home position return is performed to match the command coordinates with the machine coordinates. In the
incremental system, home position return is required every time input power is switched on. In the absolute
position detection system, once home position return is done at the time of installation, the current position is
retained if power is switched off. Hence, home position return is not required when power is switched on again.
This servo amplifier has the home position return methods given in this section. Choose the most appropriate
method for your machine structure and application.
This servo amplifier has the home position return automatic return function which executes home position
return by making an automatic return to a proper position if the machine has stopped beyond or at the
proximity dog. Manual motion by jog operation or the like is not required.
(1) Home position return types
Choose the optimum home position return according to the machine type, etc.
Type Home position return method Features
Torque limit changing dog
type home position return
With deceleration started at the front end of a
proximity dog, the position where the first
Z-phase signal is given past the rear end of the dog or
a motion has been made over the home position shift
distance starting from the Z-phase signal is defined as
a home position.
General home position return method using a
proximity dog.
Repeatability of home position return is
excellent.
The machine is less burdened.
Used when the width of the proximity dog can
be set greater than the deceleration distance of
the servo motor.

16.9.3 Torque limit changing data setting type home position return
POINT
Torque limit becomes effective after completing the torque limit changing data
setting type home position return, so that when the servo motor is rotated by
the external force, a difference occurs in between the command position and
the current position. In the home position return mode, even if a difference
occurs in between the command position and the current position, the error
excessive alarm (A52) does not occur. Therefore, when the mode is changed
from home position return to automatic operation, depending on the size of
difference between the command position and the current position, the error
excessive alarm (A52) occurs. Note that if the error excessive alarm (A52)
does not occur, the servo motor rotates to eliminate the difference.
Use the torque limit changing data setting type home position return to set the home position in any place. JOG
operation can be used for moving a position. For this home position return, torque generation is stopped at the
same time when the mode is changed to the home position return mode. Home position can be set for any
position by rotating the axis with external force.
The proximity dog (DOG) cannot be used. The proximity dog (DOG) is disabled even if it is turned off.

16.9.4 Home position return automatic return function
If the current position is at or beyond the proximity dog in the home position return using the proximity dog, this
function starts home position return after making a return to the position where the home position return can be
made.

(2) When the current position is beyond the proximity dog
At a start, a motion is made in the home position return direction and an automatic return is made on
detection of the stroke end (LSP or LSN). The motion stops past the front end of the proximity dog, and
home position return is resumed at that position. If the proximity dog cannot be detected, the motion stops
on detection of the LSP or LSN switch and A90 occurs.

This servo amplifier contains a single-axis controller. Also, all servo motor encoders are compatible with an
absolute position detection system. Hence, an absolute position detection system can be configured up by
merely loading an absolute position data back-up battery and setting parameter values.
(1) Restrictions
In the absolute position detection system, the following restriction condition applies for the number of gears
on machine-side (parameter No.PA06 CMX) and servo motor speed (N).
When CMX 2000, N 3076.7 r/min
When CMX 2000, N 3276.7 - CMX r/min
When the servo motor is operated at servo motor speed higher than the limited value, the absolute position
counter warning (AE3) occurs.

Component Description
Servo amplifier
Servo motor Use standard models.
Battery MR-J3BAT
Encoder cable Use a standard model. (Refer to section 14.1.)
(4) Outline of absolute position detection data communication
For normal operation, as shown below, the encoder consists of a detector designed to detect a position
within one revolution and a cumulative revolution counter designed to detect the number of revolutions.
The absolute position detection system always detects the absolute position of the machine and keeps it
battery-backed, independently of whether the general-purpose programming controller power is on or off.
Therefore, once the home position is defined at the time of machine installation, home position return is not
needed when power is switched on thereafter.
If a power failure or a fault occurs, restoration is easy.

(5) Battery installation procedure
WARNING
Before installing a battery, turn off the main circuit power while keeping the control
circuit power on. Wait for 15 minutes or more until the charge lamp turns off. Then,
confirm that the voltage between P( ) and N( ) is safe with a voltage tester and
others. Otherwise, an electric shock may occur. In addition, always confirm from
the front of the servo amplifier whether the charge lamp is off or not.
POINT
The internal circuits of the servo amplifier may be damaged by static electricity.
Always take the following precautions.
Ground human body and work bench.
Do not touch the conductive areas, such as connector pins and electrical
parts, directly by hand.
Before starting battery changing procedure, make sure that the main circuit
power is switched OFF with the control circuit power ON. When battery is
changed with the control power OFF, the absolute position data is lost.
