Issue:
Customer wants to know if the ATV61 has backspin protection embedded?
Product Line:
Altivar 61 ATV61
Environment:
All models
Cause:
The load forces the motor to backspin.
Resolution:
The drive can be prevented from commanding the motor to run in reverse, but there is no way to stop the motor from spinning backwards if that's what the load is forcing on it.
Incorporate a mechanical system to prevent backspin. An anti-reverse ratchet is the most common device type.
