CL57T(V4.0) Closed-Loop Stepper Drive

Motor stalls during acceleration

Current setting is too small

Choose another power supply with lager
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

Excessive motor & drive heating

Inadequate heat sinking / cooling

Refer to chapter 2.4

Motor peak current setting is too high

Reduce the current value refer to motor
datasheet

Motor vibration when power on

Speed loop Kp is too high

Reduce the speed loop Kp value
