How to resolve MECHATROLINK-II transmission cycle error on Omron SJDE-ANA-OY?
- F
  Fernando Wilson DDSSep 10, 2025
  To resolve MECHATROLINK-II transmission cycle 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 Omron SJDE-ANA-OY DC Drives showing Dynamic Brake Overload?
- S
  Scott McbrideSep 9, 2025
  A dynamic brake overload on your Omron DC Drives can occur if the servomotor does not stop 3 seconds or more after the servo was turned OFF; reconsider the load and operation conditions. Also, check if the servomotor is rotated by external force.

What to do if Omron SJDE-ANA-OY shows overcurrent?
- N
  norman31Aug 23, 2025
  If your Omron DC Drives unit is showing an overcurrent error, here are a few things you can check: * Ensure the wiring between grounding and U, V, or W is correct. * Repair or replace the servomotor main circuit cable if there's a short circuit or ground fault. * Verify the wiring of the regenerative unit. * Reconsider the load and operation conditions if there's an overload. * Correct the installation conditions to ensure the ambient temperature for the SERVOPACK is 55 °C max. * Reduce the load if the output exceeds the rating. * Check the catalogue and select the correct combination of SERVOPACK and servomotor. If none of these steps resolve the issue, it may indicate a fault with the SERVOPACK, requiring replacement or professional assistance.

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.

What causes the low load overload on Omron SJDE-ANA-OY DC Drives?
- A
  angelaperkinsSep 3, 2025
  A low load overload on your Omron DC Drives can be caused by incorrect or faulty servomotor wiring or encoder wiring; ensure these are correctly connected. If the starting torque exceeds the maximum torque, reconsider the load and operation conditions. 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.

What to do if Omron SJDE-ANA-OY DC Drives has position error pulse overflow?
- A
  Anne HortonSep 1, 2025
  If your Omron DC Drives reports a position error pulse overflow, start by checking the servomotor main circuit cable wiring and the encoder wiring for any errors. If the input position reference is too large, reduce it. Also, reduce the load if it is too large. If the problem persists, the SERVOPACK might be faulty.

What causes overload warning on Omron DC Drives?
- J
  Jerry MillerAug 30, 2025
  An overload warning on your Omron DC Drives can be triggered by several factors. Check if the servomotor wiring or encoder wiring is incorrect or has a faulty connection and correct it. If the starting torque exceeds the maximum torque, reconsider the load and operation conditions. Also, make sure that the servomotor runs with a reference input by correcting the servomotor main circuit cable wiring. If none of these are the cause, the SERVOPACK may be faulty.
