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.
