Can I Start and Stop the motor using the speed reference?

Issue:
Is it standard practice to use the speed reference to start and stop the drive while keeping the run command activated?

Product Line:
Altivar drives

Environment:
All models and serial numbers

Cause:
N/A

Resolution:
No, it is not recommended to start and stop using the speed reference. When the run command is activated, the output transistors are biased ON. This can increase the opportunity for voltage transients to cause damage. It is recommended to use a switch or relay to deactivate the run command (Digital Input) when the drive is not called to run the motor.
