Video: How can I increase the starting torque on the ATS22?

Issue:
Is there a way to adjust the torque to get the motor moving from a start position?

Product line:
Altistart 22, ATS22

Environment:
All models, all serial numbers

Cause:
The default settings in the ATS22 cannot produce enough torque to ramp up the Soft Starter, which could lead to overcurrent, overload or excessive starting time faults.

Resolution:
Increasing the parameters below can aid in providing more breakaway torque to get the motor moving and up to speed.

SET Menu:
Parameter T90 - Initial Voltage.  This value is adjustable from 10% to 50% of the full voltage, in increments of 5%.  Factory setting is 30%.
Parameter ILt - Current limit.  This is the maximum current allowed during the startup.  It is adjustable up to 700% of the Motor Rated Current (In parameter).  The maximum value is 350% of the Soft Starter rated current (IcL parameter).  Factory setting is 350%.



ADJ Menu: (To access the ADJ menu, LAC parameter under the SET menu must be set to "on")
Parameter bSt - Boost Time.  This provides an 80% pulse of the Line voltage (UIn parameter) for 0.0 to 1.0 seconds.  Factory setting is 0.0.
