4-8 Programming
Soft Start The following parameters are specifically used to adjust the voltage
ramp supplied to the motor.
➀ If the controller senses that the motor has reached full speed before completing the Soft Start, it
will automatically switch to providing full voltage to the motor.
Current Limit Start To apply a current limit start to the motor, the following parameters
are provided for user adjustment:
➀ If the controller senses that the motor has reached full speed before completing the current limit
start, it will automatically switch to providing full voltage to the motor.
Parameter Option
Starting Mode
This must be programmed for Soft Start.
Soft Start
Ramp Time ➀
This programs the time period that the controller will
ramp the output voltage up to full voltage from the
Initial Torque level programmed.
0…30 s
Initial Torque
The initial reduced output voltage level for the
voltage ramp to the motor is established and
adjusted with this parameter.
0…90% locked rotor torque
Kickstart Time
A boost of current is provided to the motor for the
programmed time period.
0.0…2.0 s
Kickstart Level
Adjusts the amount of current applied to the motor
during the kickstart time.
0…90% locked rotor torque
Parameter Option
Starting Mode
This must be programmed for Current Limit.
Current Limit
Ramp Time ➀
This programs the time period that the controller will
hold the fixed, reduced output voltage before
switching to full voltage.
0…30 s
Current Limit Level
This parameter provides adjustability for the reduced
output voltage level provided to the motor.
50…600% full load current
Kickstart Time
A boost of current is provided to the motor for the
programmed time period.
0.0…2.0 s
Kickstart Level
Adjusts the amount of current applied to the motor
during the kickstart time.
0…90% locked rotor torque
