Please note the following:

Your MSC-3 must be applied, installed and operated in a safe manner in accordance with all local rules

and regulations.

The MSC-3 is intended for use only in fixed wiring applications. It is not intended for use on a flexible

supply cable.

The MSC-3 contains a substantial EMC line filter and as a result it is unsuitable for use on earth leakage

protected circuits.

The MSC-3 contains capacitors that take greater than one minute to discharge below 50Vdc. The voltage

across these capacitors should be measured before any work is carried out inside the enclosure.

The MSC-3 contains high energy circuits that may be hazardous. Do not operate the MSC-3 with the

door or enclosure open.

Receiving

Inspect the MSC-3 for any shipping damage. If any damage is found, report it to the carrier immediately.

Access the inside of the controller and visually check for any damage.

Do not attempt to operate the MSC-3 if any obvious damage exists.

After the initial inspection, the MSC-3 can be repacked and stored in a clean, dry location until it is

required for use. DO NOT store this equipment in an area where the ambient temperature will fall below

-20°C (-4°F) or rise above 70°C (158°F). DO NOT store this equipment in areas of high condensation or

corrosive atmosphere. Proper storage is necessary to ensure satisfactory controller start up and

3 Phase MSC-3 Electrical Installation Diagram.

IMPORTANT

1. Either fuses or a circuit breaker

should be connected as shown. Fast

semiconductor fuses are not required.

2. UL compliant installations must use

UL listed fuses as per the table below.

3. Cable sizes should be selected

according to local wiring rules using

the currents given in the table below.

4. For complete motor thermal

protection microtherms or thermistors

should be installed in the motor

winding.

5. For compliance with EMC standards,

the motor wiring and ground

conductor must be enclosed in a

continuous metallic sheath or conduit,

which has good contact to both the

motor and inverter chassis. The

sheath should contain only the wiring

from one inverter and its associated

motor cables. No other conductors

may be included.

Single Phase MSC-3 Electrical Installation

Any model MSC-3 can be operated from a single phase supply. The constraints on single phase

operation are as follows:

• The single phase supply voltage must be within the 3 phase supply voltage limits for the MSC-3

model to be used. For example, use an MSC-3Lxx model for a 240VAC single phase supply or a

MSC-3Rxx model for a 480VAC single phase supply.

• A standard 3 phase motor of a voltage rating appropriate to the MSC-3 model should be used. See

the specifications section of this manual for output voltages.

• If the optional DC bus choke is fitted to an MSC-3 powered from a single phase supply, the

maximum available output voltage will decrease to 95% of the RMS input voltage. This means that

the available motor torque at full speed will be reduced to approximately 90% of the motor rated

torque. This is simply a consequence of operating the motor at lower than rated voltage. This de-

rating does not apply if the optional DC bus choke is not fitted. De-rating can also be avoided if the

single phase input voltage is 1.05 times the rated motor voltage.

• The MSC-3 is unsuitable for use with single phase motors.

• Terminals L2 and L3 should be connected together and the single phase supply should be

connected to L1 and L2. In all other respects the connections are the same as for a 3 phase supply.

• The continuous output current rating is reduced from the values stated for 3 phase supply operation

according to the graph below.

MSC-3 Start up

Connect the input and motor wiring in accordance with the Electrical Installation Diagram. Select the

terminal configuration you require from the table on page 30. Connect the control wiring according to the

appropriate Control Wiring Diagram or follow a quick setup. The MSC-3 is now ready to run. Before

applying power ensure that rotation of the motor shaft will not cause injury or damage.

After applying power it is recommended that you at least go through the MOTOR, PERFORMANCE and

the INPUT/OUTPUT menus to set up the MSC-3 before running the motor to prevent any unexpected

motor operation. The MSC-3 is supplied with a link between the En terminal and the +5V terminal which

is all that is required to run the MSC-3 from the console. A connection between these two terminals must

always be made for the motor to run.

The five pushbuttons and display form a console through which drive features and settings are altered to

suit the application. When the MSC-3 is first powered up, the start banner is displayed for approximately

2 seconds. An example of the start banner is shown below. It displays the drive size, software version

and the temperature of the MSC-3 hardware. While the banner is displayed the internal fan is switched

on to verify its operation. If the fan is not required it will then be turned off.

MSC-3 Run mode

Once the start banner is removed the display is set in the Run Mode. The top line contains the run

variable. The second line contains the speed reference and the drive status. An example of the Run

Mode display is shown below:

25.0 Hz

50.0 FWD

The example shows that the desired output speed is 50 Hz and the motor is rotating at 25 Hz in the

forward direction as indicated by the status.

To start the drive, select a direction by pressing either of the run buttons: p FWD or qREV button. Use

the p FWD button to increase the speed reference and the q REV button to decrease it. The motor

should rotate up to the desired speed. If it does not, refer to the Trouble Shooting Guide at the end of this

manual.

If the motor shaft spins in the wrong direction remove the input power, wait for the MSC-3 to discharge

and swap any two motor phase wires. Re-apply input power and select a direction by pressing p FWD or

q REV.

MSC-3 User’s Manual

IM00092A Page 21

C00 PERFORMANCE

This section allows you to set the motor performance characteristics.

C01 MIN Hz

Default value: 0 Hz

Range: 0 to 195Hz

This sets the frequency that the MSC-3 will run when given a run signal. The value is entered in Hz.

There must be a difference of at least 5Hz between the MIN Hz and the MAX Hz setting. For example, if

MAX Hz is set to 45Hz, then the largest allowed value for MIN Hz is 40Hz. Use the up or down push

buttons to adjust the MIN Hz value, press Enter to accept the value or press ESC to abort the

adjustment. It is possible to use the full span of the analog input to adjust the speed reference through

the remaining reduced speed range. For example: Max Hz = 50Hz and Min Hz = 20Hz, the analog input

“R01 Ref at 0%” should be set to 40%. Zero at the analog input will produce a reference of 20Hz. Full

span at the input will produce a reference of 50Hz.

C02 MAX Hz

Default value: 50 or 60Hz (depends on model)

Range: 5Hz to 200Hz

This sets the frequency that the drive will run with the speed reference at maximum. There must be a

difference of at least 5Hz between the MIN Hz and the MAX Hz setting. This value is scaled by the Run

Scale value and so is always entered in user defined units. Use the up or down push buttons to adjust the

MAX Hz value, press Enter to accept the value or press ESC to abort the adjustment.

C03 Ramp

MSC-3 User’s Manual

Page 22 IM00092A

C04 ACCEL TIME

Default value: 10 sec

Range: 0.5 to 600 sec

The ACCEL TIME is the time taken for the motor to go from zero speed up to motor rated speed

(assuming minimum S TIME). An MSC-3 with Motor Hz set to 50 Hz and an ACCEL TIME of 10 seconds

will take 10 seconds to go from 0 Hz to 50 Hz. Use the up or down buttons to adjust the ACCEL TIME or

press ESC to abort adjustment.

C05 DECEL TIME

Default value: 10 sec

Range: 0.5 to 600 sec

The DECEL TIME is the time taken for the motor to go from motor rated speed down zero speed

(assuming minimum S TIME). An MSC-3 with Motor Hz set to 50 Hz and an DECEL TIME of 10 seconds

will take 10 seconds to go from 50 Hz to 0 Hz. Use the up or down buttons to adjust the DECEL TIME or

press ESC to abort adjustment.

C06 S TIME

Default value: 0.01 sec

Range: 0.01 to 40.00 sec

The S TIME is the time taken for the motor to reach the limit of acceleration (as set by the rated speed

and the ACCEL TIME or DECEL TIME). Using the S TIME ensures smooth speed increases and

decreases. The longer the S TIME, the smoother the speed transition.

The S TIME will extend the ramp time as set by the ACCEL and DECEL TIME. The ramp time is now

roughly equal to the S TIME plus ACCEL TIME or DECEL TIME.

C07 Flux plus %

Default value: 25%

Range: 0 to 150% of adjustment range

The MSC-3 uses a sensorless flux vector control algorithm to control the motor operation. This control

algorithm provides independent control of motor flux throughout the speed range and is highly robust

against motor parameter changes. It uses the motor nameplate parameters entered in the B00 MOTOR

menu as the basis for its calculations to produce the correct flux in the motor. For a motor to produce full

torque it must have the correct flux applied to it. This is particularly critical at low speed. Flux Plus

adjusts the motor flux estimate to provide additional control where specific adjustments to the motor

torque response are required.

This feature enables an adjustment in the flux vector algorithm that can increase motor flux to produce

more torque for the same motor current. The amount of extra torque produced will vary from motor to

motor depending on motor size, efficiency and the operating speed.

Increase the value to produce more torque. This should be done in small steps to ensure the drive does

not go into Current Limit. If the drive does go into current limit decrease the Flux Plus value slightly.

This is the maximum torque that the motor can produce.

Use the up or down buttons for the adjustment. Press Enter when adjusted or ESC to abort adjustment.

C08 Hi Spd Flux+

Available Choices: H00 ENABLE

H01 DISABLE (default)

When this is disabled the flux plus decreases with increasing speed. This allows more efficient operation

of the MSC-3 on loads that have a high starting torque but do not require any extra torque during normal

operation. If your load requires high torque throughout the entire speed range Enable Hi Spd Flux+.

Press Enter to view the setting. Use the up or down push button to enable or disable Hi Spd Flux+. Press

Enter to accept the new setting or ESC to abandon.

MSC-3 User’s Manual

IM00092A Page 23

C09 SLIP COMP

Default value: 0%

Range: 0 to 150% of slip speed

Motor slip is the difference between the shaft speed and the frequency applied to the motor (synchronous

speed) and is dependent on load. Slip Comp can provide compensation for this varying slip to produce

constant shaft speed under varying loads. The MSC-3 estimates the slip of the motor using the

parameters entered in the MOTOR parameters menu and the motor load. A value of 100% will make the

shaft speed equal the synchronous speed. Flux Plus may be used in conjunction with Slip Comp to

provide increase output torque at low speeds. Press Enter then use the up and down buttons to adjust

the amount of SLIP COMP. When adjusted, press Enter to accept the new setting or ESC to abort the

adjustment.

C11 AUDIBLE FREQ

Available Choices: C12 2kHz

C13 4kHz

C14 8kHz

C15 16kHz

C16 Auto select (default)

This value sets the maximum frequency that the drive uses in the creation of its PWM output voltage.

This frequency is noticeable as an audible sound that the motor makes. Usually higher settings produce

less audible noise but increase the switching losses which produces more heat in the drive. For most

efficient operation select 2 kHz. Press Enter then use the up or down buttons to choose the AUDIBLE

FREQ. Press Enter when finished to accept the choice or ESC to abort.

MSC-3 User’s Manual

D00 PROTECTION

This section lets you set the motor protection features.

D01 CURRENT LIM

Default value: drive overload current.

Range: 18 to100% of Drive Overload Current listed in MSC-3 Output Current Specifications

table on page 44, entered in amps.

This sets the maximum output current of the MSC-3. If excessive load is applied to the motor, the drive

will only apply this amount of current to the motor until the overload condition is removed. Current

limiting is achieved by reducing the speed of the motor. The Current Limit value cannot be set higher

than the maximum output current for the drive.

Press Enter then use the up or down buttons to adjust the CURRENT LIM. Press Enter when finished to

accept the adjustment or ESC to abort.

D02 I2t

The I

2t feature estimates the heating of the motor according to the motor load. When the estimated

heating exceeds I2t setting, the drive will trip on I2t. For a motor running at 110% of its I2t current this will

take approximately two minutes. The time to trip will shorten the further the motor current exceeds the I2t

value.

If power is removed from the drive after an I2t trip, the motor should be allowed to cool down before the

inverter is restarted. Motors running highly loaded at low speeds should have external cooling and an

external motor thermal sensing device such as microtherms or thermistors for protection.

The I2t feature has the ability to set the trip threshold as a function of output frequency. This allows the I2t

to protect motors that have reduced cooling at low speeds because they are not externally cooled. The

diagram below is an example of the I2t trip threshold profile.

D02 I2t

Default value: drive nominal current

Range: 18% to 100% of drive Overload Current listed in MSC-3 Output Current Specifications

table on page 44, entered in amps.

This sets the upper limit of I2t and is entered in amps. This is equivalent to the usual I2t setting. Use the

up and down push buttons to adjust the D02 I2t value and press Enter to accept the value or ESC to

abandon changes.

D03 I2t zero Hz

Default value: drive nominal current

Range: 18% to 100% of drive Overload Current listed in MSC-3 Output Current Specifications

press Enter to accept the value or ESC to abandon changes.

D04 I2t cnr Hz

Default value: 10Hz

Range: 2 to 200Hz

The D04 I2t cnr Hz value sets the frequency above which the profile uses the trip threshold as set by

D02 I2t. Below this frequency the I2t value is set by the slope on the I2t profile. Use the up and down

push buttons to adjust the D04 I2t value and press Enter to accept the value or ESC to abandon

changes.

D05 Reverse

Available Choices: H00 ENABLE

H01 DISABLE (default)

The MSC-3 is shipped with its reverse direction disabled to prevent damage to mechanical devices or

hazardous equipment operation caused by the motor running backwards. Press Enter to view the setting.

Use the up or down push button to enable or disable Reverse. Press Enter to accept the new setting or

ESC to abandon.

D08 DC INPUT

Available Choices: H00 ENABLE

H01 DISABLE (default)

least 1.414 times higher than the motor voltage. Press Enter to view the setting. Use the up or down

push button to enable or disable DC Input. Press Enter to accept the new setting or ESC to abandon.

E00 STOP/START

This section sets the motor stopping and starting modes.

E01 STOPPING

Available Choices: E02 RAMP TO STOP (default)

E03 COAST

This controls the operation of the MSC-3 when any stop signal is given.

RAMP TO STOP means that the MSC-3 will continue to control the motor in order to bring it to a stop in

the time set by the DECEL TIME and S TIME.

COAST means that the MSC-3 will stop controlling the motor and allow it to coast to a stop, just as if the

power supply had been disconnected.

E06 DYNAMIC BRK

Available Choices: H00 ENABLE

H01 DISABLE (default)

Dynamic Braking provides the means for dissipating the motor regenerative energy into an external

resistor. This may be required when the MSC-3 experiences regenerative currents from an overhauling

load or a high inertia load that is required to decelerate rapidly. Dynamic Braking requires the dynamic

braking option to be connected to the MSC-3. Please see the dynamic braking instruction manual for

resistor sizing and dynamic braking application information.

Use the up or down buttons to select either Enable or Disable. Press Enter to accept the selection or

ESC to abort.

MSC-3 User’s Manual

Page 26 IM00092A

E07 AUTO RESTART

Auto Restart allows the MSC-3 to automatically attempt to restart after a trip occurs. If the MSC-3 trips it

will wait 10 seconds then attempt to clear the fault. If it is unsuccessful it will keep trying every ten

seconds. It will do this the number of times specified in A/Rs ALLOWED. If the fault is cleared and the

drive runs without tripping for the A/R CLR TIME the number of auto restarts attempted will start counting

from 1 again. If the trip is cleared by any other means the fault count will start from 1 again.

Note: Alteration to any of the Auto Restart parameters is not permitted while the MSC-3 is operating in

ESO mode.

E08 A/Rs ALLOWED

Default value: 0

Range: 0 to 15 restarts

This number indicates how many times the MSC-3 will attempt to restart after a trip. For the motor to run

after the trip is cleared, the drive must be given a valid run command. Select 0 restarts in order to de-

activate Auto Restart.

Use the up or down buttons to adjust A/Rs ALLOWED. Press Enter to accept the adjustment or ESC to

abort.

E09 A/R CLR TIME

Default value: 20 min

Range: 0.1 to 20 min

If the MSC-3 operates for the A/R CLR TIME without any trips occurring the number of restarts is reset to

the value of A/Rs ALLOWED. Set the A/R CLR TIME to 0.1min for infinite auto restarts.

Use the up or down buttons to adjust A/R CLR TIME. Press Enter to accept the adjustment or ESC to

abort.

E10 Reset by PF

Available Choices: H00 ENABLE

H01 DISABLE (default)

Enabling this facility allows the MSC-3 to reset all trips when a momentary power failure occurs. This

feature is useful in power-up start applications because trips may be cleared without any extra switch

logic by turning the power off and straight back on again without waiting for the drive to completely power

down.

Use the up or down buttons to select either Enable or Disable. Press Enter to accept the selection or

ESC to abort.

Speed References

R00 AN1

When the Analog Input is selected as a speed reference for any of the different operating modes, two

parameters need to be checked. The MSC-3 will let you do this every time the analog input is selected

as a reference. They are R01 REF AT 0% and R02 REF AT 100%. Use the up or down buttons to

change the values (if required). Press enter to accept the value or ESC to abort.

MSC3 Analog Input Scaling

To calculate the values for REF AT 0% and REF AT 100% you need to know the following:

• Two analog input values and the speed required at each value

• The maximum speed.

• The input range, 5V, 10V or 20mA

Now use the following formulae to calculate the values for REF AT 0% and REF AT 100%

Examples:

Standard 4-20mA

At 4mA input we want 0Hz and at 20mA

input we want 50Hz, maximum speed

50Hz using the 0-20mA input range.

Bipolar Input

At 1V input we want 40Hz in reverse and

R01 REF AT 0%

Default value: 0%

Range: - 1000% to 1000%

This value specifies what the reference will be when 0% of the input signal is present at the analog input

terminals. For a 4 to 20mA input signal, R01 REF AT 0% must be set to –25%.

R02 REF AT 100%

Default value: 100%

Range: -1000 to 1000% of input span

This value specifies what the reference will be when 100% of the input signal present at the analog input

terminals.

R03 PRESET

Default value: 60%

Range: -100% to 100% of CO2 MAX Hz

If PRESET is chosen as the speed source you must enter the preset speed value. Use the up or down

buttons to adjust the preset speed. The preset speed is entered in % of CO2 MAX Hz. Press Enter to

accept the speed value or press ESC to abort.

R04 MOTORIZD POT

Motorised Pot operation requires two input terminals, Up and Down. If the Up terminal is energised the

drive speed will increase. If the Down terminal is energised the speed will decrease. If neither is

energised the drive maintains a constant speed. If MOTORIZD POT is selected as the speed source you

must select the mode of operation.

Available choices: R05 PersistENT

R06 RESET (default)

Use the up or down buttons to select either R05 PERSISTENT or R06 RESET. Press Enter to accept the

selection or ESC to abort.

In PERSISTENT mode the Motorized Pot speed will be remembered when power is removed. The

Motorized Pot reference will return to this value the next time the MSC-3 is run.

In RESET mode the Motorized Pot speed will not be remembered when power is removed. The

Motorized Pot reference will always start from zero after power is applied.

R07 CONSOLE REF

When this is selected, the reference is set from the console using the up and down arrows when the

MSC-3 is in the run mode.

MSC-3 User’s Manual

G00 INPUT/OUTPUT

There are two ways to assign terminal strip functions in the MSC-3.

The user can choose a standard terminal configuration from the standard list.

The user can create a custom terminal configuration.

The simplest way to set a terminal configuration is to choose from one of the standard terminal

configurations tabulated below. From the console menu press enter. Use the up arrow and down arrow

buttons to move through the list of standard terminal configurations CONFIG 1 - CONFIG 8. When you

have chosen a configuration press the enter button. Selecting one of these loads the terminals with the

listed functions. The MSC-3 does not remember which configuration was selected but remembers

the individual terminal functions. It does this so that you can then modify any of the terminals to suit

your specific application. This also means that every time you go to the G01 Terminal CFG menu, the

first option displayed is G02 CONFIG 1. To see the terminal configuration you must look at each terminal

individually.

Note: The MSC-3 must be disabled to select another terminal configuration.

Remember if you make a mistake press the escape button twice. This will take you out of the menu

mode and move you into the run mode.

Display Messages

The MSC-3 displays a variety of messages on the second line of its display to indicate the drive status.

These messages may be divided into two types, trip messages and run messages.

The MSC-3 will protect itself under a variety of fault conditions. When one of these conditions is

experienced the MSC-3 will trip, shut down the motor output and display one of the following messages.

The message will be displayed until the fault is cleared and a reset signal is applied.

Trip Message Meaning

OPT SC An output short circuit has been detected. This is caused by either

an Over Current or a Ground Fault on the motor terminals.

OV The DC Bus voltage has exceeded its maximum value.

OC The output current has exceeded the MSC-3’s continuous output

current rating.

DC LOW The DC Bus voltage has fallen below its minimum threshold.

PWR FAIL All input phases on the input power supply are either low or

missing.
