9 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.
