Mounting Instructions
There must be a clearance of at least 5-7/8 inches (150 mm) in all
directions. A good bonding between the SED2 and the metal backplate is
necessary to ensure good grounding and low RFI (radio frequency
interference). If necessary, remove some backplate paint and/or use
toothed washers to ensure safety and EMC (electro-magnetic
compatibility). Earth braid screened armored cable provides the best
bond.

NOTE: Install the SED2 vertically for optimum cooling. Do not
obstruct the vents on the SED2. Additional ventilation may be
required if the SED2 is mounted horizontally.
SED2 VFD Startup, Operation, and Maintenance Manual
22 Siemens Building Technologies, Inc.
Electrical Installation
DANGER:
• To ensure safe operation of the SED2, authorized persons
must install and commission it in full compliance with the
warnings, cautions, and notes in this manual. Authorized
persons must also follow general and regional installation
and safety regulations regarding working with high voltages
as well as relevant regulations for the correct use of tools
and protective equipment.
• The SED2 must be grounded (per IEC 536, Class 1, NEC
and other relevant industry standards). Extremely
hazardous conditions may result if the SED2 is not correctly
grounded.
NOTE: IP20 and NEMA Type 1 SED2s can operate in
ungrounded systems if the Y capacitor is
disconnected or removed.
IP54, NEMA Type 12 SED2s cannot operate in
ungrounded systems. See the Operation in
Ungrounded Systems section for more details.
• The SED2 is suitable for use in a circuit capable of
delivering not more than 10,000 symmetrical amperes, for
a maximum voltage of 240/480/575V when protected by a
time delay Type J, H, or K fuse or circuit breaker.
• Always wait 5 minutes after disconnecting the SED2 from
the power source before performing any work. The DC link
capacitors of all SED2s remain charged with dangerous
voltages for 5 minutes after all power sources have been
disconnected. When working on IP20 units, note that live
parts are exposed. Do not touch these parts.
• In cases where a fault in the input or output power wiring
could cause significant equipment damage or severe
physical injury (such as potentially dangerous short
circuits), use additional external precautions to ensure safe
operation (such as independent limit switches and
mechanical interlocks).
Electrical Installation
Siemens Building Technologies, Inc. 23
Extended Storage: Conditioning of
Capacitors
After an extended period of storage, recharge the capacitors in the SED2.
Calculate the storage time from the date of manufacture or the date code,
and not from the date of delivery. (See the Interpretation of Serial
Numbers and Date Codes section for more details.) The recharge
procedure varies according to the storage period as follows:
Period of
Storage Required Action Total Preparation
Time
1 year or less Recharging not required. No preparation
1 to 2 years Before issuing the “run” command, connect
the SED2 to input power for one hour. 1 hour
2 to 3 years Use a variable AC power source as follows:
• Apply 25% of the input voltage for
30 minutes.
• Increase the voltage to 50% for an
additional 30 minutes.
• Increase the voltage to 75% for an
additional 30 minutes.
• Increase the voltage to 100% for an
additional 30 minutes.
The SED2 is then ready for operation.
2 hours
3 or more
years Use a variable AC power source as follows:
• Apply 25% of the input voltage for
2 hours.
• Increase the voltage to 50% for an
additional 2 hours.
• Increase the voltage to 75% for an
additional 2 hours.
• Increase the voltage to 100% for an
additional 2 hours.
The SED2 is then ready for operation.
8 hours
CAUTION:
After an extended period of storage, if capacitors are not
properly recharged, catastrophic damage to the drive can
result.
SED2 VFD Startup, Operation, and Maintenance Manual
24 Siemens Building Technologies, Inc.
Input Power and Motor Connections
DANGER:
• Make certain that the motor rated full load amps (FLA)
does NOT exceed the rated output current of the SED2
controlling it.
When multiple motors are simultaneously operated by the
SED2, the sum of all motor rated FLA values must be
less than or equal to the SED2 controlling them.
• Never switch on the SED2 with it open.
• Always isolate the input power cables before connecting
them to the SED2.
• Always use insulated tools when working on input power
and motor terminals.
• Ensure that terminal covers are securely replaced after
connecting the input power and motor cables.
WARNING:
• Verify that the SED2 and motor are correctly rated for the
input power voltage.
• Verify that the input power cables are correctly sized for
the anticipated use.
• Confirm that appropriate circuit breakers or fuses have
been installed between the input power supply and the
SED2.
• Never use high-voltage insulation test equipment on any
cables connected to the SED2.
Electrical Installation
Siemens Building Technologies, Inc. 25
Operation in Ungrounded Systems
IP20 and NEMA Type 1 SED2s can operate in ungrounded systems if the
Y capacitor is disconnected or removed. They remain in operation when
an input ground fault occurs. In the event of an output ground fault, the
SED2 switches off and displays fault code F0001.
NOTE: IP54, NEMA Type 12 SED2s cannot operate in ungrounded
systems.
Ungrounded Systems and Y Capacitor
In ungrounded systems, remove or disconnect the Y capacitor (and install
an output choke/load reactor) per Figures 8 through 11.

Input Power Connection
DANGER:
• As supplied, the SED2 must be grounded (per IEC
536, Class 1, NEC and other relevant industry
standards). Extremely hazardous conditions can occur if
the SED2 is not correctly grounded.
• Use only permanently wired input power connections.
Only hard-
wired input power connections are permissible.
Use Class 1 60/75° copper wire only.
• The cross-section of the ground-bonding conductor must
be at least equal to the input power cables.
• The following terminals can carry hazardous voltages
even when the SED2 is not running:
− Input power terminals: L1, L2, L3
− Motor terminals: U, V, W
− Link terminals: DC-, DC+/B+, DC/R+, B- (not for
customer use)
Connect input power to SED2 terminals L1, L2, and L3 (Figures 19
through 22).
SED2 VFD Startup, Operation, and Maintenance Manual
38 Siemens Building Technologies, Inc.
Motor Cable Length
Maximum motor cable length is 164 ft (50m). Motor cable length is given
to ensure performance of only the SED2, not the suitability of the motor
when connected to a SED2 at this distance.
M
SED2
3. If needed, use
SBT-specified input line
reactors to ensure a good
impedance match with
your drive.
1. Never run control or drive input
wires in the same conduit as
the drive output wires.
4. If a disconnect is mounted on the
load side of your drive, it is desirable
to wire an auxiliary contact to the drive
that will disable drive operation when
the disconnect opens. (The wiring for
this contact must not be run in the same
conduit as the drive output wires).
5. Inverter duty motors are recommended.
Install motors within their guidelines. Use
dV/dT filters, output reactors, or other load
conditioners as applicable or as specified
by the motor manufacturer.
2. Keep the distance from the drive
to the motor as short as possible
to maximize motor life.

NOTE: If connecting multiple motors to one SED2, the total length of
the individual motor cables must not exceed the maximum
motor cable length.

Motor Connection
(Wye "Y"/Star or Delta Configuration)
DANGER:
Do not use the SED2 with a motor of higher nominal power
rating than the SED2, or a nominal power less than half that
of the SED2. Only operate the SED2 when the nominal
current (P0305) is set to match motor rating continuous
current.
The motor nameplate indicates the required supply voltage and method of
connection. In general, larger 400/690V motors connect in a delta (∆)
configuration and smaller 230/400V motors connect in a Wye “Y” or star
configuration (Figure 24).
Connect motor wiring to SED2 terminals U, V, and W (Figures 19 through
22).

Direction of Motor Rotation
To change the direction of motor rotation, cross-connect two of the output
conductors on the SED2 (Figure 25). This is the desired method for
changing rotation.
NOTE: The Reverse Output Phase Sequence parameter (P1820) can
also reverse the direction of rotation. However, if the SED2 is
reset to factory defaults, P1820 is reset to OFF.

Motor Overload Protection
WARNING:
The SED2 is capable of providing internal motor overload
protection in accordance with UL508C, Section 42. Accurately
configure motor parameters for the motor overload protection
to operate correctly. See Motor I2t Temperature Reaction
parameter (P0610); I2t is On by default.
Motor overload protection also can be provided using an
external PTC temperature-thermistor sensor (disabled by
default via Motor Temperature Sensor parameter (P0601)).
During operation below nominal speed, the cooling effect of the fans
mounted to the motor shaft is reduced. Therefore, most motors require
de-rating if operated continuously at low frequencies. To ensure that
motors are protected from overheating under these conditions, mount a
PTC temperature-thermistor sensor to the motor and connect it to the
control terminals of the SED2.
NOTE: To enable the switch-off function with a PTC temperature-
thermistor sensor, set Motor Temperature Sensor parameter
(P0601) to 1 for PTC temperature-thermistor sensor. Use a
shielded cable to connect the PTC temperature-thermistor
sensor.

Connection of Multiple
Motors
The SED2 can control several motors in
parallel as long as all of the motors have
the same power rating. When multiple
motors connect to the SED2 in parallel,
the motors cannot operate individually.
NOTES:
1. When determining the required
power, take into account the total
current from all the motors (or the
total of all ratings).
2. The sum of all individual motor cable
lengths must not exceed the
maximum motor cable length.

Parameters
Overview
The SED2 uses parameters to define the required operating
characteristics, such as motor data, ramp times, and maximum and
minimum frequency. Users enter and modify the SED2 parameters using
the Basic Operator Panel, the Advanced Operator Panel, or a serial
interface.
Each parameter consists of the letter "r" or "P", followed by four
numbers, such as r0000 or P0010. The letter "r" identifies read-only
parameters. The letter "P" identifies programmable parameters.
Parameter Structure
Figure 36 depicts the structure of the SED2 parameters.
• User Access Level parameter (P0003) selects the access level for
using the parameters (1=standard, 2=extended, or 3=expert). The
access level selected via parameter P0003 determines the number
of parameters that are accessible by the user. For most applications,
the Standard (1) and Extended (2) levels are sufficient. The factory
default setting is P0003=1 (Standard).
• The filters of Parameter Filter parameter (P0004) categorize the
parameters that are available via the access level according to
functionality. The filters/categories enable a more focused
operational approach. If parameter P0004=0 for no filter/category,
then all parameters for a selected user access level are available.
NOTE: Some parameters are intended for commissioning only and
can be viewed as a function of this filter. In order to set these
parameters, P0010 must be set to 1 (quick commissioning).
Parameter Indexes
Certain parameters have indexes. The indexes provide subsets of a
particular parameter function and group together closely related
parameter type information. The Parameter Reference Guide (Document
Number 125-3214) lists any indexes associated with a parameter.
SED2 VFD Startup, Operation, and Maintenance Manual
50 Siemens Building Technologies, Inc.
The following indexes are associated with P0700, P1000, and digital
input and output parameters:
• IN000 (AUTO), 1st command data set (CDS)
• IN001 (HAND), 2nd command data set (CDS)
The following indexes are associated with analog input and output
parameters:
• IN000, Analog input 1, AO1
• IN001, Analog input 2, AO2
NOTE: Throughout this manual, a parameter number followed by [0]
or [1] denotes index number 000 or 001 respectively.

SED2 Operator Panels
Overview
The SED2 includes the Basic Operator Panel (BOP) mounted as
standard. An Advanced Operator Panel (AOP) is available as an option.
Figure 37. Basic Operator Panel
(BOP).
Figure 38. Advanced Operator
Panel (AOP).
NOTES:
1. On initial startup, the SED2 display values alternate
between 0.0 Hz (zero) and the speed it would be running if
it were given a start command.
2. The BOP or AOP can connect to or disconnect from the
SED2 without switching off power.
Basic Operator Panel (BOP)
The BOP provides access to the parameters of the SED2 and allows for
application-specific settings of the SED2.
The parameters and measured values are shown in a 5-digit LCD
display. The BOP can mount directly onto the SED2 or, alternatively, it
can mount into a control cabinet door using a special installation kit
(SED2-DOOR-KIT1 or SED2-DOOR-KIT2).
The BOP cannot store parameter data.

WARNING:
• Only authorized personnel trained in the setup, installation,
commissioning, and operation of the SED2 may work on the
product and mechanical system.
• SED2s operate at high voltages. In some components,
operation of electrical equipment involves using dangerous
voltages.
• In cases where faults in the control equipment could cause
significant equipment damage or severe physical injury (such
as potentially dangerous short circuits), use external
precautions to ensure and to enforce safe operation (such as
independent limit switches and mechanical interlocks).
• Emergency stop facilities must remain functional in all operating
modes of the control equipment. Resetting the emergency stop
facility must not result in an uncontrolled or undefined restart.
Do not use the SED2 as an emergency stop mechanism.
• The equipment incorporates internal motor overload protection
in accordance with UL508C, Section 42. See Motor I2t
Temperature Reaction parameter (P0610); I2t is ON by default.
(Motor overload protection can also be provided with an
external PTC temperature-thermistor sensor disabled by default
via Motor Temperature Sensor parameter (P0601). See the
Motor Overload Protection section in this manual for details.)
For reliable motor overload protection, the motor parameters
must be configured accurately.
• Certain parameter settings can cause the SED2 to start
automatically or to restart automatically after a fault or an input
power failure (provided the fault is eliminated or acknowledged
or the supply voltage is restored).

Prerequisites to Startup Procedure
To ensure reliable SED2 operation and to avoid any extra costs related
to loss or reduction of warranty coverage, a factory certified specialist
should complete this startup procedure.
Complete the following checklist and maintain it in a secure location as
service personnel may request this information.
CAUTION:
The SED2 has no isolating switch on the input power and is live as
soon as the input power is connected. The SED2 remains with the
output disabled until you press (green start pushbutton) or until it
receives a digital On command signal.
Check Step
( ) 1. The SED2 is thoroughly tested at the factory. Verify that the
SED2 is free of shipping and installation damage. Shipping
damage is not covered by the Siemens Building
Technologies, Inc. warranty; claims must be filed directly
with the shipping company as soon as possible.
( ) 2. Verify that the model numbers and the voltage ratings are as
specified in the purchase order by matching the nameplate
data of each unit to the purchase order.
( ) 3. Review the appropriate sections of this manual and verify
that the mechanical and electrical installation procedures
are complete.
Review any option instructions and job schematics provided
with the SED2.
CAUTION:
Failure to comply with mechanical and electrical installation
requirements may void the product warranty.
( ) 4. Verify that the 50/60 Hz DIP switch has been set to the
appropriate setting, as instructed in the Motor Frequency
and Unit of Measurement DIP Switches section of this
manual.
SED2 VFD Startup, Operation, and Maintenance Manual
58 Siemens Building Technologies, Inc.
( ) 5. Inspect the security of the input power wiring, ground
connections, motor wiring, and all control circuit
connections, as identified in the SED2 documentation.
IMPORTANT: Verify that the cross–section and length of
the input power and motor cables are
correct.
IMPORTANT: Confirm that the input power connects to
the SED2 input terminals: (L1, L2, L3)
and NOT to the output motor terminals:
(U, V, W).
IMPORTANT: Verify that all input power wires (L1, L2, L3)
and motor wires (U, V, W) are securely
tightened down to their lugs. Loose wire
connections may cause problems at any
time, and are not covered under warranty.
( ) 6. Review the installer’s as-wired schematic. Determine where
the motor safety circuit is connected. Verify that the
customer’s emergency contacts are properly terminated in
the SED2 safety shutdown circuit or bypass option.
Verify that all other field-installed wires are correctly
terminated (including the shields).
( ) 7. Verify the motor is free to move mechanically.
( ) 8. For pump applications, verify the medium (such as water) is
available (no dry run).
( ) 9. Record the motor(s) nameplate information:
Voltage: Service Factor:
Efficiency %: Full Load Amps (FLA):
RPM: Hp:
( ) 10. Verify that the input power voltage matches the rating of the
SED2.
( ) 11. Verify that the motor is wired for the application voltage.
( ) 12. IMPORTANT: Verify that the motor rated full load amps
(FLA) does NOT exceed the rated output
current of the SED2 controlling it.
When multiple motors are simultaneously operated by the
SED2, the sum of all motor rated FLA values must be less
than or equal to that of the SED2 controlling them.
Commissioning
Siemens Building Technologies, Inc. 59
( ) 13. Record any other connections to the SED2 by terminal
number to determine if special programming is required.
Record any changes in Appendix A: Parameters, Defaults,
and Settings.
( ) 14. Make certain the immediate area around the SED2 is free of
debris and miscellaneous items.
( ) 15. If applicable, verify that the building automation system logic
is ready to perform adequately for start, stop, and speed
command functions.
This concludes the preparation process for SED2 startup.
Keep this manual, option schematics, and any other instructions sent
with the SED2 easily accessible to assist you through the remainder of
this startup process.
SED2 (stand-alone) Startup
Procedure
NOTE: For SED2 with bypass option, see the documentation
provided with bypass for startup instructions.
Check Step
( ) 1. Make sure that all three power phases are present and that
the input voltage is correct for the SED2 being started.
Apply SED2 power and verify that the SED2 display is on.
If the display indicates a fault, press to reset it.
( ) 2. Perform quick commissioning according to the Quick
Commissioning Procedure section in this manual.
On completion of the quick commissioning procedure,
proceed to step 3.
( ) 3. Press and to return to the SED2 operating mode.
Press to place SED2 in Hand mode.
( ) 4. To start the SED2, press (green start pushbutton). The
SED2 will ramp up to 10 Hz (or minimum speed). Verify
that the direction of motor rotation is correct.
CAUTION:
If the direction of motor rotation is wrong, turn power Off!
SED2 VFD Startup, Operation, and Maintenance Manual
60 Siemens Building Technologies, Inc.
DANGER:
Wait for 5 minutes. Always wait 5 minutes after
disconnecting the SED2 from the power source before
performing any work. The DC link capacitors of all SED2s
remain charged with dangerous voltages for 5 minutes
after all supplies have been disconnected. When working
on open equipment, note that live parts are exposed. Do
not touch these parts.
Swap wires on the motor terminals (U, V) or on the output
terminals of the motor overload relay. Tighten the terminal
lugs, reapply power, and recheck the direction of motor
rotation.
( ) 5. With correct motor rotation, manually run the SED2
throughout its entire operating range while observing
operation.
If the SED2 trips on over-current during acceleration,
increase the acceleration time rate via parameter P1120.
If the SED2 trips on over-voltage during deceleration,
adjust the deceleration time rate via parameter P1121.
If excessive vibration of the driven load is noted at specific
frequencies, use Skip Frequency parameters P1091
through P1094 to eliminate this vibration.
( ) 6. Determine whether the remote speed reference is a 0 to
10 Vdc or a 4 to 20 mA signal. Connect or verify
connection of signal wires. Set or verify that analog input
DIP switch has been set to the appropriate setting as
instructed in the Analog Input DIP Switches section of this
manual.
( ) 7. Check the signal for proper polarity. Observe if the remote
speed command can achieve the minimum and maximum
speeds desired. If not, scale as required. The signal value
can be read at r0752 and the scaled value can be read at
r0754.
( ) 8. Make additional SED2 application parameter settings as
required and record them in Appendix A: Parameters,
Defaults, and Settings.
( ) 9. Press to place SED2 in Auto mode.
This completes the startup procedure for the SED2.

Quick Commissioning Procedure
Parameter P0010 is the Commissioning Parameter Filter. It allows you to
select a group of parameters that can be used for quick commissioning,
including motor data (Figure 39), and motor ramp-up and ramp-down
settings.
It is important to use parameter P0010 to commission the SED2, P0003
to select the access level for using parameters, and P0004 to filter the
parameters according to their functionality. When Commissioning
Parameter Filter P0010=1, it initiates the quick commissioning
procedure.
It is recommended that you use the quick commissioning procedure.
However, experienced users may commission the equipment without the
P0004 filter functions.
At the end of the quick commissioning procedure, set parameter
P3900=1. This setting performs the necessary motor calculations and
sets all remaining parameters (those not included in P0010=1) to the
factory default values. If P3900 is set to a value greater than 0, P0010 is
automatically reset to 0. (If P0010=1, the SED2 cannot start.) The
process of performing motor calculations and setting all parameters to
factory default values is only possible via quick commissioning.

• LAST FAULT (r0947(0)) shows the code for the most recent fault.
Fault history displays according to Figure 40, where:
F1 = The first active fault (not yet acknowledged)
F2 = The second active fault (not yet acknowledged)
F1e = The occurrence of the fault acknowledgement for F1 and F2.
This moves the value in the two indexes down to the next pair of

• For example:
If the SED2 trips on undervoltage and then receives an external trip
before the undervoltage is acknowledged, you will obtain:
Index 0 = 3, undervoltage
Index 1 = 85, external trip
Whenever a fault in index 0 is acknowledged (F1e), the fault history
shifts as indicated in the diagram.
• Indexes:
r0947[0] = Recent fault trip –, fault 1
r0947[1] = Recent fault trip –, fault 2
r0947[2] = Recent fault trip -1, fault 3
r0947[3] = Recent fault trip -1, fault 4
r0947[4] = Recent fault trip -2, fault 5
r0947[5] = Recent fault trip -2, fault 6
r0947[6] = Recent fault trip -3, fault 7
r0947[7] = Recent fault trip -3, fault 8
Index 2 is used only if a second fault occurs before the first fault is
acknowledged.
Resetting Faults
• Press to reset a fault condition manually.
• OK FAULT (r0052, bit 3) is a read-only fault status point (0=OK,
1=Fault). It can be acknowledged with FAULT ACK (r0054, bit 7).
Setting FAULT ACK (r0054, bit 7) resets the fault (1=Reset Fault).
• It is possible that motor performance may be affected at low
frequencies if parameter P1310 falls under 50% (default value).
• It is recommended to make provision to reset faults automatically if
the unit is operated in auto mode.

Troubleshooting Using the Operator
Panel
NOTE: The voltage and current range of the SED2 must match the
motor data.
If the motor does not start with the ON command:
1. Check if Commissioning Parameter Filter P0010=0 (factory setting).
2. Check if there is a valid ON signal.
3. Check if Selection of Command Source parameter P0700[0]=2 (for
digital input control) or P0700[1]=1 (for BOP control).
4. Check if the correct setpoint is available (0 to 10V on terminal 3), or if
the setpoint was entered in the correct location for the setpoint
source (Selection of Frequency Setpoint parameter P1000[0]=2).
If the motor does not start after checking these parameters, reset the
SED2 to the factory-default parameter values according to the Reset to
Factory Defaults section in this manual.
Use a switch between terminals 5 and 9 on the control terminal bar. The
SED2 should now run according to the default setpoint at the analog
input.
Use r0722 to check on/off status of digital inputs. Use r0752 to check the
smoothed value of analog inputs.

Glossary
Access Level
The degree of authorization a user has when using SED2 parameters.
Also see User Access Level parameter P0003.
ADC
Analog to Digital Converter; refers to analog inputs.
AOP
Advanced Operator Panel.
Boost
Applies an offset relative to the rated motor current. Boost is useful for
loads with high inertia. Also see Continuous Boost parameter P1310,
Acceleration Boost parameter P1311, and Starting Boost parameter
P1312.
BOP
Basic Operator Panel.
CDS
Command Data Set.
Control Mode
Controls relationship between speed of motor and voltage supplied by
SED2. Also see Control Mode parameter P1300.
DAC
Digital to Analog Converter; refers to analog outputs
DC Braking
Causes the motor to stop rapidly by applying a DC braking current
(current applied also holds motor shaft stationary). When the DC braking
signal is applied, the SED2 output pulses are blocked and the DC current
is not applied until the motor has been sufficiently demagnetized. Also
see Enable DC Braking parameter P1230).
EMC
Electromagnetic Compatibility.
SED2 VFD Startup, Operation, and Maintenance Manual
118 Siemens Building Technologies, Inc.
EMI
Electromagnetic Interference.
Fixed Frequency
Frequency setpoints that are based on selection of a predetermined
source.
Flying Start
Starts SED2 onto a spinning motor by rapidly changing the output
frequency of the SED2 until the actual motor speed has been found.
Then, the motor runs up to setpoint using the normal ramp time.
Inverter
Another term for a variable frequency drive (VFD).
IP20
IP20 is the enclosure rating for the standard SED2 from Europe; there is
no equivalent North American enclosure rating. An enclosure with an
IP20 rating is protected against penetration of solid objects greater than
0.47 inches (12mm) and it is protected against vertically falling drops of
water such as from condensation.
Mains
Another term for input line power.
Motor I2t Temperature
Provides a model for estimating the thermal motor value; used for
internal motor overload protection. Also see Motor I2t Temperature
Reaction parameter P0610 and Motor temperature Sensor parameter
P0601.
Motor Pole Pairs
One of the pole pairs is called a winding.
NEMA Type 1
NEMA Type 1 SED2s include gland plates (frame sizes A through C) and
protection shields. An enclosure with a NEMA Type 1 rating is intended
for indoor use, primarily to provide a degree of protection against contact
with the enclosed equipment or for locations where unusual service
conditions do not exist. NEMA Type 1 enclosures protect the operator
from electric hazard and protect the equipment from falling material.

NEMA Type 12/IP54
IP54 is a European enclosure rating; there is no equivalent North
American rating, although it exceed the NEMA Type 12 rating. An
enclosure with a NEMA Type 12 rating is intended for indoor use,
primarily to provide a degree of protection against dust, falling dirt, and
dripping non-corrosive liquids. An enclosure with an IP54 rating is
protected against dust (limited ingress, no harmful deposit) and it is
protected against water sprayed from all directions (limited ingress
permitted).
OFF1
The OFF1 command stops the SED2 within the selected ramp-down
time (P1121).
OFF2
The OFF2 command causes a free coasting of the motor to a standstill
(impulses for the power section of the SED2 are disabled).
OFF3
The OFF3 command causes the motor to decelerate rapidly.
Overcurrent
A SED2 fault condition that occurs, for example, when motor power is
greater than SED2 power. Also see Fault Code F0001.
Overvoltage
A SED2 fault condition that occurs, for example, when the input line
power is too high or if the motor is in regenerative mode (caused by fast
ramp downs or if the motor id drive from an active load). Also see Fault
Code F0002.
Parameter Filter
Functional categories of parameters that are available to a user. Also
see Parameter Filter P0004.

Parameter Index/Indexes
Subsets of closely related information associated with a particular
parameter function.
For example, the following indexes are associated with P0700, P1000,
and digital input and output parameters:
IN000 (AUTO), 1st Command Data Set (CDS)
IN001 (HAND, 2nd Command Data Set (CDS)
The following indexes are associated with analog input and output
parameters:
IN000, Analog Input 1
IN001, Analog Input 2.
PID
Proportional, Integral, Derivative.
Quick Commissioning
Predefined procedure consisting of fundamental parameters to configure
the SED2 for operation.
Ramp-down Time
Time for the motor to ramp down. Also see Ramp-down Time parameter
P1121.
Ramp-up Time
Time for the motor to ramp up. Also see Ramp-up Time parameter
P1120.
RFG
Ramp Function Generator.
RFI
Radio Frequency Interference.
Skip Frequency
Frequencies that are skipped to avoid effects of mechanical resonance.
Also see Skip Frequency parameter P1091.

Slip Compensation
Dynamically adjusts the output frequency of the SED2 so that the motor
speed is kept constant independent of the motor load. Also see Slip
Compensation parameter P1335.
Stator Resistance
Impedance produced from each motor winding.
Train (HVAC)
Sequence or succession of mechanical equipment.
Undervoltage
A SED2 fault condition that occurs, for example, when input line power
has failed or is outside the voltage reduction tolerance. Also see Fault
Code F0003.
VFD/VSD
Variable Frequency Drive/Variable Speed Drive. Both terms are used for
a device that controls the frequency or speed of another device such as
a fan or pump motor.
