12. Frequently Asked Questions
In the event that your drive doesn’t operate properly, the first step is to identify whether the problem is electrical or mechanical in nature.
The next step is to isolate the system component that is causing the problem. As part of this process you may have to disconnect the
individual components that make up your system and verify that they operate independently. It is important to document each step in the
troubleshooting process. You may need this documentation to refer back to at a later date, and these details will greatly assist our
Technical Support staff in determining the problem should you need assistance.
Many of the problems that affect motion control systems can be traced to electrical noise, controller software errors, or mistake in
wiring.
