How to fix polarity detection failure A.C50 on YASKAWA SGDV-OFB03A Servo Drives?
- K
  Kevin VelezAug 10, 2025
  If you encounter a 'Polarity Detection Failure A.C50' with your YASKAWA Servo Drives, it could be due to several reasons. First, verify that the resolution and motor phase selection (Pn080.1) settings are correct, referring to the encoder specifications and feedback signal conditions. Also, noise in the scale signal can cause this issue; ensure proper grounding and check the encoder cable. If the motor is experiencing external torque, try to reduce it, or increase the speed loop gain (Pn481). Finally, if the resolution is too rough, consider using the recommended resolution or increasing the command speed (Pn493), noting that this will increase the movement range.

What to do if overtravel is detected during polarity detection A.C51 on YASKAWA Servo Drives?
- B
  brendaweberAug 17, 2025
  If you are experiencing an 'Overtravel Detected during Polarity Detection A.C51' alarm with your YASKAWA Servo Drives, this indicates that the OT signal was detected during the polarity detection function. To resolve this, ensure that the motor is positioned where the OT signal is not detected before initiating the function.

Why polarity detection failure 2 A.C54 occurs on YASKAWA SGDV-OFB03A?
- P
  Patricia BauerAug 25, 2025
  If you are facing a 'Polarity Detection Failure 2 A.C54' with your YASKAWA Servo Drives, it might be due to external torque being applied to the motor. To address this, try increasing the confirmation torque command (Pn495) and the allowable error range (Pn498). Keep in mind that increasing the error range may also increase the motor temperature.

What to do if YASKAWA Servo Drives show out of range of motion for polarity detection A.C53?
- A
  Anna WallaceAug 31, 2025
  If you encounter an 'Out of Range of Motion for Polarity Detection A.C53' error with your YASKAWA Servo Drives, it means the movement range during detection has been exceeded. If the range (Pn494) is at its default value, investigate why the motor might have moved unexpectedly and take appropriate corrective actions.
