Cause:
The VFD is not responding to the stop command.
Resolution:
1). Verify how the drive is receiving the stop command.
2). Verify if the drive is programmed to get the stop command from that source.
3). Verify the drive is not in local control.
4). Check if the run signal is jumpered/bypassed
5). Check to see if the motor is backfeeding voltage back into the drive.
