9.2. Troubleshooting Faults
When the troubleshooting below calls for "power cycle" here is the
procedure: turn off power to the motor, wait 30 seconds, turn power
back on to the motor to restart. Note that the drive automatically retries
after the 30 second wait time. Number of retries is not limited; drive will
retry until the fault condition is cleared and a successful restart is
achieved..
