What to do if YASKAWA SGMGH show a dividing ratio setting error?
- J
  Jorge FernandezAug 7, 2025
  If your YASKAWA Servo Drives are showing a dividing ratio setting error, it could be due to an incorrect setting of the dividing ratio (Pn212). This setting might be unacceptable or exceed the value for the connected encoder resolution. To resolve this, correct the setting of Pn212, then turn the control power OFF and then ON again. Alternatively, the error could be caused by a fault in the SERVOPACK EEPROM or the related circuit, in which case, you should replace the SERVOPACK.

  If your YASKAWA Servo Drives display an 'Encoder Model Unmatched' error, it could be because the connected serial encoder is not supported by the SGDM SERVOPACK. The suggested solution is to replace the servomotor with an SGDM SERVOPACK supported model. Another potential cause is a SERVOPACK board fault, which would require replacing the SERVOPACK.

What to do if YASKAWA Servo Drives show Parameter Setting Error?
- G

  If YASKAWA Servo Drives display a Parameter Setting Error, it could be due to an out-of-range parameter being set or loaded. Try resetting all parameters within the range or reload the correct parameter. If the issue persists, the circuit board (1PWB) may be defective, requiring replacement of the servo amplifier.

What causes YASKAWA Servo Drives to display A.02 Parameter Breakdown?
- A
  Anthony HarrisonAug 22, 2025
  The A.02 Parameter Breakdown error in YASKAWA Servo Drives can be caused by a power interruption during parameter writing, leading to an alarm upon the next power cycle. It may also indicate a defective circuit board (1PWB). To resolve this: * Initialize parameters using Fn005, then re-enter the settings. * If the problem continues, replace the servo amplifier.

What to do if YASKAWA Servo Drives show Servomotor and Amplifier Combination Error?
- J
  jimmy79Aug 27, 2025
  If your YASKAWA Servo Drives are showing a Servomotor and Amplifier Combination Error, it could be due to exceeding the acceptable range of servomotor capacities. In this case, replace the servomotor to achieve an acceptable combination. Another potential cause is improperly written encoder parameters, which would also necessitate replacing the servomotor.

Why YASKAWA SGMGH Servo Drives display Main Circuit Detection Error?
- M
  Megan SpencerSep 1, 2025
  YASKAWA Servo Drives may display a Main Circuit Detection Error if the circuit board (1PWB or 2PWB) is defective. The suggested solution is to replace the servo amplifier.
