Soft Start Configuration Application Notes
1. Voltage Ramp Start Configuration
Default values may be used for start time and initial torque.
Kick Start Torque = 0% (fans and pumps), 75% (high breakaway loads)
Kick Start Time = 0 sec (fans and pumps), 1 sec (high breakaway loads)
Start the motor and determine the worst case starting conditions. Adjust initial torque for
smooth start without hesitation. Motor rotation should begin within two seconds.
If stall faults occur at the end of the ramp time, increase Initial Torque, Kick Start Torque and
Time and/or Soft Start Time to get into bypass before the Soft Start Time elapses. Also, verify
that the motor is not overloaded.
2. Current Limit Start Configuration
Initial settings:
Initial Torque = 50%
Soft Start Time = 60 sec
Kick Start Torque = 0%
Kick Start Time = 0 sec (disabled)
3. Start the motor and determine the worst case starting conditions. Adjust Initial Torque for
smooth start without hesitation. Rotation should begin within two seconds and the motor
should smoothly accelerate to full speed.
4. If stall faults occur, increase Initial Torque and/or Soft Start Time to get into bypass before the
Soft Start Time elapses. Also, verify that the motor is not overloaded. Verify that the motor is
not in a stall condition. A stall condition will be noted when the motor does not continue to
accelerate during the start ramp.
5. After suitable performance has been achieved, determine the starting time to bypass and set
Soft Start Time at 1.25 times this time. For example, if it takes 10 seconds to accelerate the
motor and go into bypass, set the Soft Start Time for 12.5 seconds. Adjust the Soft Stop Time
for the desired stopping time.
