    Tips: What should be checked before powering on the stepper motor?

    1. Check whether the power is proper (in case of overvoltage, the drive module may be damaged); the positive and negative polarity of DC input should not be wrong. Whether the motor type or current setting on the drive controller is proper (not too large at the very beginning).
    2. Control signal line is connected firmly and it’s better to give considerations into the problem about shielding (like using twisted-pair) at the industrial field.
    3. At the very beginning, do not directly connect all necessary lines but the most basic system, and then connect one by one after the motor rotates in good state.
    4. Be clear about earthing methods, or don’t connect it.
    5. Closely observe the state of motor within 30min after the motor rotates, like whether it rotates normally, as well as sound and temperature rise. If discovering the problem, please stop it and make adjustment.
