  If your Oriental motor Engine does not operate, several factors could be the cause. First, check the connections between the driver and the power supply to ensure they are correctly connected. Second, verify that the operation switch is set to the "RUN" side, not "STAND-BY". If operating the motor using the operation switch, ensure the "external operation signal input" parameter is set to "OFF" after setting the operation switch to the STAND-BY side. When using external signals, the "external operation signal input" parameter should be set to "ON" or "RE" after turning the input operation signal OFF. Also, make sure either the FWD or REV input is ON, but not both. Finally, check for any alarms and reset after addressing the cause.

Why is my Oriental motor BMUD120-A2 Engine rotating in the wrong direction?

  If your Oriental motor Engine rotates in the opposite direction to what you specified, there are a few potential causes. First, the FWD and REV inputs might be wrongly or not correctly connected; check these connections. Second, the gear ratio might be causing the gearhead output shaft to rotate in the opposite direction; consult the motor's operating manual for the gearhead output shaft's rotation direction. Also, check the rotation direction switch. Finally, if the rotation direction switch is set to REV, verify the setting of the "external operation signal input" parameter.

  If the operation of your Oriental motor Engine is unstable, or if the motor vibration is too great, there are a couple of things you should check. First, make sure that the motor and gearhead output shaft are correctly aligned with the load shaft. Second, check for electrical noise by testing the operation with only the essential equipment (motor, driver, and any other external equipment required for operation). If noise is present, try moving the unit away from noise sources, reviewing the wiring, changing to shielded signal cables, or installing ferrite cores.
