12. Frequently Asked Questions

In the event that your driver 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.
