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 mistakes in wiring.
