Soft Start
The following parameters are specifically used to adjust the voltage
ramp supplied to the motor.
①
If the controller senses that the motor has reached full speed before completing the voltage ramp,
it will automatically switch to providing full voltage to the motor.
Current Limit Start
To apply a fixed reduced output voltage to the motor, the following
parameters are provided for user adjustment:
①
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.

Ramp Time #1
①
This programs the time period that the controller will
ramp the output voltage up to full voltage from the
Initial Torque level programmed.
0 to 30 seconds
Initial Torque #1
The initial reduced output voltage level for the
voltage ramp to the motor is established and
adjusted with this parameter.
0 to 90% locked rotor torque
Kickstart Time
A boost of 550% full load current is provided to the
motor for the programmed time period.

Ramp Time #1
①
This programs the time period that the controller will
hold the fixed, reduced output voltage before
switching to full voltage.
0 to 30 seconds
Current Limit Level
This parameter provides adjustability for the reduced
output voltage level provided to the motor.
50 to 600% full load current
Kickstart Time
A boost of 550% full load current is provided to the
motor for the programmed time period.
