Issue:ATV212 flashing StOP when changing from utility to generator power
Product Line:
ATV21, ATV212
Environment:
All models and serial numbers.
Cause:
Momentary power loss removes output power to motor.
Resolution:
When F302, supply loss behavior, is activated, then a brief loss of input power will cause the drive to remove power from the motor and display the flashing StOP alarm. To restart operation, remove and reapply a new run command signal. To deactivate this function and attempt to ride through the momentary loss of power, set F302 back to the factory default of 0.
