Issue:
ATS48 with ULF (under load fault).
Product Line:
Altistart 48
Environment:
All serial numbers
Cause:
Drive is detecting an under load fault?
Resolution:
ULF is an under load fault. The fault is caused by parameter settings on the soft starter. In the PRO menu parameter ULL (Activation of motor under load) enables the under load detection. Parameter LUL (Motor underload threshold) set the percentage of torque for the underload detection. Parameter TUL (Motor underload time), set the time delay before ULL faults when the motor torque falls below LUL threshold.
