Programming 4-9
1560D-UM051D-EN-P – February 2005
Soft Start The following parameters are specifically used to adjust the voltage ramp
supplied to the motor.
Parameter Option
Starting Mode
This must be programmed for Soft Start.
Soft Start, Current Limit
Ramp Time #1 X
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.
0.0 to 2.0 seconds
X 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:
Parameter Option
Starting Mode
This must be programmed for Current Limit.
Soft Start, Current Limit
Ramp Time #1 X
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.
0.0 to 2.0 seconds
X 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.
