How to troubleshoot MECHATROLINK-II communication errors on Omron DC Drives?
- K
  Katrina HarrisSep 5, 2025
  To troubleshoot MECHATROLINK-II communication errors on your Omron DC Drives, if communications with the host controller disconnected while the MECHATROLINK-II connection was established, turn the power supply OFF and then ON again, or send a DISCONNECT command to release communications and set up communications again. Ensure the MECHATROLINK-II wiring is correct and terminators are properly connected. If noise interference is present, take measures against noise and reconsider wirings for MECHATROLINK-II communications cable and FG, also attach a ferrite core to the MECHATROLINK-II communications cable.

Why is my Omron SJDE-ANA-OY DC Drives showing overspeed?
- T
  Taylor ParkerAug 25, 2025
  An overspeed error on your Omron DC Drives can occur due to several reasons. First, check if the order of phases U, V, and W of the servomotor wiring is correct. Also, verify the encoder wiring. Noise interference in the encoder line can also cause this issue, so take appropriate measures against noise. If the input position reference is too large, reduce the reference value. If none of these steps resolve the issue, the SERVOPACK may be faulty.

How to fix overvoltage in Omron SJDE-ANA-OY?
- A
  aimee14Aug 26, 2025
  To address an overvoltage issue in your Omron DC Drives, ensure that the AC power supply voltage is within the specified range and not exceeding 290 V. Also, check for excessive changes in AC power supply voltage during operation and maintain it within the specified limits. If the servomotor speed is high and the load moment of inertia is excessively large, reconsider the load and operation conditions or install a regenerative unit. If the issue persists, the SERVOPACK might be faulty.

What to do if emergency stop signal is not working on Omron SJDE-ANA-OY?
- T
  Todd MeyerAug 27, 2025
  If the emergency stop signal is not working on your Omron DC Drives, ensure that the emergency stop signal is correctly wired. If the emergency stop signal was input, refer to section 4.7.5 in the manual for the correct operation sequence. Also, check the wiring for any malfunctions on the emergency stop signal, and correct it if necessary.

Why Omron SJDE-ANA-OY indicates high load overload?
- L
  Lindsey MartinAug 27, 2025
  An overload error with a high load indication on your Omron DC Drives typically means that the effective torque exceeds the rated torque, or the starting torque largely exceeds the rated torque. To resolve this, reconsider the load and operation conditions. If the problem persists, the SERVOPACK may be faulty.

How to cool down overheated Omron DC Drives board?
- C
  Chris HahnAug 28, 2025
  If the board of your Omron DC Drives is overheated, check the following: ensure that the ambient temperature around the SERVOPACK is kept to 55 °C max by correcting the installation conditions. If the load exceeds the rating, reconsider the load and operation conditions and the servomotor capacity. Also, if the overload alarm was often reset by turning off the power supply, reconsider the load and operation conditions and the servomotor capacity. If the problem still occurs, the SERVOPACK might be faulty.

What causes current detection error in Omron SJDE-ANA-OY DC Drives?
- Z
  zshafferSep 6, 2025
  A current detection error in your Omron DC Drives can be caused by a disconnected servomotor main circuit cable; check and correct the wiring. If the wiring is correct, the SERVOPACK may be faulty.

What to do if Omron DC Drives detects servo overrun?
- D
  David HudsonSep 4, 2025
  If your Omron DC Drives detects a servo overrun, verify that the order of phases U, V, and W in the servomotor wiring is correct. Also, the encoder might be faulty. If the problem persists, the SERVOPACK may be faulty.

Why Omron SJDE-ANA-OY DC Drives displays undervoltage?
- A
  Amy ClarkSep 2, 2025
  An undervoltage error on your Omron DC Drives can occur if the power supply was turned ON again before the SERVOPACK power supply was turned OFF. To fix this, turn ON the power supply again after the REF LED goes out. If a temporary power failure occurred, reset the alarm and then restart the operation. If the issue persists, the SERVOPACK may be faulty.
