CL57T(V4.0) Closed-Loop Stepper Drive
Restart the power supply, if the drive is
still alarm, please contact after-sale
a) Set SW6 to “ON” to make motor run
in open loop mode, If alarm disappears,
it means encoder wiring error;
b) Motor torque is not enough or motor
speed is too high;
Restart the power supply, if the drive is
still alarm, please contact after-sale
When above protections are active, the motor shaft will be free or the red LED blinks. Reset the drive by repowering it
to make it function properly after removing above problems.
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.
