What to do if my Oriental motor BMU Engine does not operate?
- K
  Katherine SparksAug 19, 2025
  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 BMU rotating in the wrong direction?
- M
  Madeline GallowayAug 21, 2025
  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.

What to do if the Oriental motor BMU operation is unstable or vibrating too much?
- J
  Joe GrantAug 25, 2025
  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.

Why is the set rotation speed not saved on my Oriental motor BMU?
- S
  Sarah McneilAug 27, 2025
  If the set rotation speed is not being saved on your Oriental motor Engine, ensure that you are confirming the speed by pressing the setting dial after you set it.

Why is the rotation speed not displayed on my Oriental motor Engine?
- T
  Thomas GonzalezAug 30, 2025
  If the rotation speed is not displayed on your Oriental motor Engine, the "panel initial view" parameter might not be set to show the rotation speed. Set the "panel initial view" parameter to the rotation speed.

Why is my Oriental motor BMU not reversing with the rotation direction switch?
- B
  Benjamin MillerAug 31, 2025
  If your Oriental motor Engine is not reversed by the rotation direction switch, check the setting of the "external operation signal input" parameter. It may be set to "RE."

Why is my Oriental motor Engine rotating in the opposite direction?
- P
  Patrick CarlsonSep 2, 2025
  If your Oriental motor Engine rotates in the opposite direction, several factors could be the cause. First, check the connection of the FWD input and REV input to ensure they are correctly connected. Also, verify the gear ratio, ensuring the gearhead output shaft rotates in the same direction as the motor. Check the rotation direction switch to ensure it is properly set. Lastly, if the rotation direction switch is set to REV, verify the setting of the "external operation signal input" parameter.

How to fix unstable operation and excessive vibration in my Oriental motor BMU?
- C
  Christopher SkinnerSep 4, 2025
  Unstable operation and excessive vibration in your Oriental motor Engine can stem from a few issues. Check the coupling condition of the motor, gearhead output shaft, and the load shaft to ensure proper alignment. Also, check for electrical noise by testing the motor with only essential equipment. If noise is present, consider moving the unit away from noise sources, reviewing the wiring, changing signal cables to shielded types, or installing ferrite cores.
