Questions and Answers

    What to do if Oriental motor BLHM230K does not rotate?
    • J
      James GarciaAug 15, 2025
      If the Oriental motor Engine does not rotate, several issues could be the cause. First, check the power supply connection to ensure it is correct. Next, verify that the operation input signal is turned ON, using the internal I/O monitor or D-I/O monitor to check the signal input status. Also, confirm that the correct operation data number is selected and that the motor connector is properly connected. If an alarm is present (PWR/ALM LED blinks red), check the alarm content by counting the LED blinks or using the MEXE02. Finally, ensure the operation data is set correctly, using the status monitor to check the setting method and value.

    What to do if Oriental motor BLHM230K Engine motor movement is not stable and motor vibration is too large?
    • H
      hernandezjessicaAug 18, 2025
      If the Oriental motor Engine's movement is unstable or the vibration is too large, check the following: Ensure the motor and gearhead output shaft, and the load shaft are properly aligned. Verify that the motor output power and the driver output power are matched. Also, check for electrical noise affecting the product by testing the operation with only the motor, driver, and minimum external equipment.

    Why Oriental motor BLHM230K Engine does not move according to the set operation data?
    • R
      Ralph GatesAug 21, 2025
      If the Oriental motor Engine does not move according to the set operation data, consider these potential causes: The operation data number may be selected incorrectly, or the motor connector may not be properly connected; check the connection and the ON-OFF status of the signal, using the internal I/O monitor or D-I/O monitor. The setting method or value might be wrong; verify the setting method using the status monitor. A load may be too large; check if the torque is sufficient. An external analog setting device or PWM signal input may be set incorrectly; check the setting value of the "External setting method" parameter.

    Why Oriental motor BLHM230K rotates in the opposite direction?
    • R
      Robert Peck PhDAug 25, 2025
      If the Oriental motor Engine rotates in the opposite direction to what is expected, there are several potential causes: the ON-OFF operation of the FWD/REV input may be used incorrectly, or the FWD/REV input may not be connected correctly, so check the connection and the ON-OFF status of signal, using the internal I/O monitor or D-I/O monitor; the setting of the "Motor rotation direction" parameter may have been changed (the motor rotates forward when the FWD/REV input is ON); a gearhead with a reduction ratio that reverses the rotation direction of the motor output shaft may be in use (reverse the ON-OFF status of the FWD/REV input or invert the logic level setting of the input); or a hollow shaft flat gearhead is used (it rotates opposite to the motor when viewed from the front).

    What to do if Oriental motor BLHM230K stopping time is long?
    • J
      Jessica SchmittAug 27, 2025
      If the stopping time for the Oriental motor Engine is long, it could be due to the stopping method being wrongly selected. Check the stopping method; in 3-wire mode, stopping by turning the RUN/BRAKE input OFF differs from turning the START/STOP input OFF. Also, if the load inertia is too large, increase the frictional load or reduce the load inertia.

    Why Oriental motor BLHM230K rotation speed cannot be increased?
    • D
      Daniel Booth PhDAug 30, 2025
      The rotation speed of your Oriental motor Engine might not be increasing because the set rotation speed is equal to or higher than the value set in the "Speed upper limit" parameter. To resolve this, reconsider the setting value of the "Speed upper limit" parameter or operation data.

    Why Oriental motor Engine torque cannot be limited?
    • T
      Tracy WoodardSep 2, 2025
      The torque of your Oriental motor Engine cannot be limited if the TL input is turned OFF, as this disables the torque limiting function. To resolve this, check the connection and the ON-OFF status of the signal, using the internal I/O monitor or D-I/O monitor.
  • J
    Jessica GreeneSep 5, 2025
    Why Oriental motor Engine rotation speed cannot be decreased?
    • T
      Todd FigueroaSep 5, 2025
      The rotation speed of your Oriental motor Engine might not be decreasing because the set rotation speed is lower than the value set in the "Speed lower limit" parameter. To resolve this, reconsider the setting value of the "Speed lower limit" parameter or operation data.

    What does it mean when the PWR/ALM LED blinks orange on Oriental motor Engine?
    • C
      Christopher KingSep 8, 2025
      If the PWR/ALM LED on your Oriental motor Engine is blinking orange, it indicates that information is present. To address this, check the generated information using the information monitor or internal I/O monitor, and then clear the cause of generation or disable the "INFO action" parameter.

    Why Oriental motor BLHM230K torque limiting value is not increased?
    • T
      Timothy ReyesSep 12, 2025
      The torque limiting value for your Oriental motor Engine might not be increasing because the value set in the "Torque limiting maximum value" parameter is exceeded. To resolve this, reconsider the setting value of the "Torque limiting maximum value" parameter or operation data.
