Product Line:
ALTIVAR 212
Environment:
All
Cause:
Ride through functionality in case of communications faults.
Resolution:
Set parameter F851 = 1
In case of a network communication loss, the VFD will not go to a fault status, but rather continue with the last commanded operation. If stopped, it will remain stopped. If running, it will remain running at the last speed reference given.
Consider safety ramifications for this action.
