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.
