What causes Omron Servo Drives deviation counter overflow?
- H
  hernandezcherylSep 14, 2025
  A deviation counter overflow in Omron Servo Drives can occur due to: * Servomotor power or encoder line is wired incorrectly. Rewire correctly. * Locked mechanically. Repair if the Servomotor shaft is locked. * Control panel error. Replace the Servo Driver. * Occurs when rotating at high speed. Servomotor power or encoder line is miswired. * Occurs when long command pulses are sent. Gain adjustment is insufficient. * Acceleration and deceleration is too violent. Lengthen acceleration and deceleration time. Use position command filter (Pn207.0, Pn204, and Pn208). * Load is too large. Lighten the load. Reselect the Servomotor.

How to fix Omron Servo Drives multi-turn limit mismatch (ABS)?
- T
  Troy WadeSep 14, 2025
  If you're encountering a multi-turn limit mismatch (ABS) with your Omron Servo Drives, it could be because Pn205 (absolute encoder rotation limit setting) changed. Perform absolute encoder rotation limit setting change (Fn013). Alternatively, if Pn205 (absolute encoder rotation limit setting) changed by mistake, set Pn205 correctly.

How to troubleshoot Omron Servo Drives runaway detected?
- J
  Julie RobertsSep 13, 2025
  If your Omron Servo Drives have detected a runaway condition, it's likely due to the encoder or Servomotor power line being wired incorrectly. Correct the wiring.

What to do if Omron Servo Drives have command input reading error?
- C
  Christina SpencerSep 12, 2025
  If your Omron Servo Drives are showing a command input reading error, it could be due to command input reader misoperation. Reset the alarm, then re-start the operation. If the issue persists, it might be because the command input reader is broken, and you should replace the Servo Driver.

What causes Omron Servo Drives encoder overheating (ABS)?
- H
  Hannah KimSep 10, 2025
  Encoder overheating (ABS) in Omron Servo Drives can be caused by: * Encoder is defective. Replace the Servomotor. * Ambient Servomotor temperature exceeds 40°C. Lower the ambient temperature to 40°C or less. * Servomotor spring mounting clip is too small. Use a spring mounting clip the same dimensions or greater than those of the radiation shield indicated in the Servomotor efficiency specifications. * Operating above rated output. Lighten the load.

Why Omron Servo Drives show overload?
- K
  Katherine LawsonAug 25, 2025
  If your Omron Servo Drives display an overload, it could be due to: * Running at over 245% of rated torque (effective torque). In this case, repair the Servomotor shaft if it is locked. If the Servomotor power line is wired incorrectly, rewire it correctly. Lighten the load. Lengthen the acceleration and deceleration times. Adjust the gain. * Fallen power supply voltage. Check the power supply voltage, and lower to within tolerance range.

Why Omron Servo Drives show absolute error?
- S
  Sara CrosbySep 8, 2025
  An absolute error in Omron Servo Drives can occur due to several reasons: * Absolute encoder sensor check error (internal encoder error). Turn OFF the power supply, then ON again. Take noise countermeasures. Replace the Servomotor (if the cause is encoder error). * Encoder is defective. Replace the Servomotor. * Servo Driver is defective. Replace the Servo Driver.

What to do if Omron Servo Drives show battery error (ABS)?
- J
  James SotoSep 7, 2025
  If your Omron Servo Drives display a battery error (ABS), it means the absolute encoder battery voltage has fallen (to 2.7 V or less). Replace the battery while the control circuit power supply is ON.

How to troubleshoot Omron Servo Drives checksum error (ABS)?
- M
  Michael McneilSep 6, 2025
  If you're experiencing a checksum error (ABS) with your Omron Servo Drives, it indicates an absolute encoder memory check error. Set up the absolute encoder correctly.
