Common problems of Mitsubishi stepper motors are as follows:
1. The motor does not rotate: overload stall, whether the motor is offline, whether the control system has a pulse signal to the stepper motor driver, and whether there is a problem with the wiring.
2. Motor jitter: whether the frequency of the input pulse signal is too high, and whether the frequency reduction design is unreasonable.
3. Under what circumstances is the offline signal FREE of the hybrid stepper motor driver generally used? When the offline signal FREE is low, the current output from the driver to the motor is cut off, and the motor rotor is in a free state (offline state).
In some automation equipment, if the motor shaft is required to be rotated directly (manual mode) when the drive is unpowered, the FREE signal can be set low, so that the motor is offline for manual operation or adjustment. After manual completion, set the FREE signal high to continue automatic control.
