Phase Error Protection
Motor power lines wrong & not connected will activate this protection. RED LED will turn on four
times within each periodic time (3 s).
Attention: When above protections are active, the motor shaft will be free or the LED will turn red.
Reset the Drive by repowering it to make it function properly after removing above problems. Since
there is no protection against power leads (﹢,﹣) reversal, it is critical to make sure that power
supply leads correctly connected to Drive. Otherwise, the Drive will be damaged instantly.

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.
