Parameter Descriptions

1 Motor Data-1
The parameters in Motor Data-1 configure the soft starter to match the connected motor. These parameters describe
the motor's operating characteristics and allow the soft starter to model the motor's temperature.
1A – Motor FLC
Range: 5 - 1000 A
Description: Matches the starter to the connected motor's full load current. Set to the full load current (FLC)
rating shown on the motor nameplate.
1B – Locked Rotor Time
Range: 0:01 - 2:00 (minutes:seconds)
Description: Sets the maximum length of time the motor can sustain locked rotor current from cold before
reaching its maximum temperature. Set according to the motor datasheet.
1C – Locked Rotor Current
Range: 400% - 800% FLC
Description: Sets the locked rotor current of the connected motor, as a percentage of full load current. Set
according to the motor datasheet.
1D – Motor Service Factor
Range: 100% - 120%
Description: Sets the motor service factor used by the thermal model. If the motor runs at full load current, it
will reach 100%. Set according to the motor datasheet.
2 Start/Stop Modes-1
2A – Start Mode
Options: Constant Current (default)
Description: Selects the soft start mode.
2B – Start Ramp Time
Range: 0:01 - 3.00 (minutes:seconds)
Description: Sets the ramp time for current ramp starting (from the initial current to the current limit).
2C – Initial Current
Range: 50% - 600% FLC
Description: Sets the initial start current level for current ramp starting, as a percentage of motor full load
current. Set so that the motor begins to accelerate immediately after a start is initiated.
If current ramp starting is not required, set the initial current equal to the current limit.
2D – Current Limit
Range: 50% - 600% FLC
Description: Sets the current limit for constant current and current ramp soft starting, as a percentage of motor
full load current.
2E – Reserved
Reserved for future use.
2F – Kickstart Time
Range: 0 – 2000 milliseconds
Description: Sets the kickstart duration. A setting of 0 disables kickstart.
2G – Kickstart Level
Range: 100% - 700% FLC
Description: Sets the level of the kickstart current.
CAUTION
Kickstart subjects the mechanical equipment to increased torque levels. Ensure the motor, load and
couplings can handle the additional torque before using this feature.
