Error 1: Drive did not start (No Speed at Startup)
Cause:
Main computer board calls for the drive motor to start, but the drive controller responds with 0 for more
than 5 seconds (the drive motor didn’t start).
Service:
The only known cause of Error 1 has been a drop in communications or corrupted communications.
These have not been ‘hard’ or repeatable events.
• If the E-stop connection is open or intermittent, the drive can attempt to start and end up with an Error
1.
• A communication problem can result in Error 1, stemming from issues with the console cable, drive
or MCC. They will likely be accompanied by other comm errors such as 9, 98, 99.
• ESD could cause intermittent issues with communications.
• Older equipment ignores the E-stop key on power-up, so if the key is out, the console is unaware.
Normal use will result in Error 1 until the key is replaced.
• Check the cabling from the console to the motor controller.
