Why is my StepperOnline CL57T Control Unit motor not rotating?
- N
  Nicholas CaseAug 22, 2025
  Your StepperOnline Control Unit motor might not be rotating due to several reasons: * There is no power. Ensure the power supply is correctly connected. * The microstep resolution setting is incorrect. Set an appropriate microstep. * A fault condition exists. Check the wiring and restart the power. * The drive is disabled. Restore the drive to factory settings and keep ENA+, ENA- input signals unconnected.

Why does my StepperOnline CL57T Control Unit motor stall during acceleration?
- D
  David YoderAug 27, 2025
  Your StepperOnline Control Unit motor might stall during acceleration due to: * Current setting is too small. Choose another power supply with larger power or increase the output current of drive. * Motor is undersized for the application. Choose another motor with higher torque. * Acceleration is set too high. Reduce the acceleration. * Power supply voltage too low. Choose another power supply with large voltage output.

- T
  Timothy CrawfordAug 25, 2025
  If your StepperOnline Control Unit motor motion is erratic: * Ensure the current of the control signal is within 7-16mA, because the control signal might be too weak. * Make sure the control signal cable is not tied together with the power cable, because the control signal may be interfered with. * Refer to the user manual of the drive and motor datasheet to check for wrong motor connection. * Check if there is something wrong with motor coil.
