What is SSC in an ATS22 softstart?

Issue:
Meaning of SSC in ATS22.

Product Line:
ATS22, Altistart 22

Environment:
All

Cause:
n/a

Resolution:
SSC turned ON means that Acceleration ACC and deceleration DEC ramping are controlled by estimating motor torque.
SSC turned OFF means that the softstart will ramp the output voltage based on the set times for ACC and DEC.

It is recommended to set SSC = OFF if the ATS22 is oversized for the load or the ramping experiences oscillations..
