How to fix speed deviation on YASKAWA PG-X3 Controller with PG control mode?
- G
  Gregory BurkeAug 18, 2025
  If you're experiencing speed deviation with your YASKAWA Controller in PG control mode, here are some potential causes and solutions: * The load might be too heavy: Try reducing the load. * Acceleration and deceleration times might be too short: Increase the acceleration and deceleration times using parameters C1-01 through C1-08. * The load might be locked up: Check the machine. * Parameters might be set inappropriately: Verify the settings of parameters F1-10 and F1-11. * The motor brake might be engaged: Ensure the motor brake releases properly.

What to do if YASKAWA PG-X3 Controller shows 'Overspeed'?
- C
  Catherine BennettAug 21, 2025
  If your YASKAWA Controller is showing an overspeed error, it could be due to overshoot. Try the following: * Increase the settings for C5-01 (Speed Control Proportional Gain 1) and reduce C5-02 (Speed Control Integral Time 1). * Enable Feed Forward Control and perform Inertia Auto-Tuning in CLV.

What causes PG disconnected error on YASKAWA PG-X3 and how to fix it?
- A
  Amy MorganAug 23, 2025
  A 'PG Disconnected' error on your YASKAWA Controller can be caused by several issues: * The PG cable is disconnected: Reconnect the cable. * The PG cable wiring is incorrect: Correct the wiring. * The PG encoder doesn't have enough power: Ensure the correct power supply is properly connected to the PG encoder. * The brake is holding the PG: Ensure the brake releases properly.

What does 'Z Channel Pulse Fault Detection' mean on YASKAWA PG-X3?
- R
  Robert JohnsonAug 28, 2025
  The 'Z Channel Pulse Fault Detection' error on your YASKAWA Controller indicates that the PG encoder is disconnected, not wired properly, or the PG option or PG are damaged. To resolve this: * Rewire the PG encoder, ensuring all wiring, including shielded wiring, is properly connected. * If the problem persists after cycling power, replace the PG option or the PG encoder.

What causes 'Inversion Prevention Detection' on YASKAWA Controller?
- T
  Tiffany BeckerAug 30, 2025
  The 'Inversion Prevention Detection' on your YASKAWA Controller can be triggered by: * The Z channel pulse offset not being properly set to E5-11: Set the value for ?? to E5-11 as specified on the motor nameplate. If the problem continues after cycling power, replace the PG option or the PG encoder. Replacing the PG encoder or changing the application so the motor rotates in reverse requires readjustment of the Z channel pulse offset. * Noise interference along the PG cable affecting the A or B pulse: * Make sure the motor is rotating in the proper direction. * Investigate problems on the load-side that may be causing the motor to rotate in the opposite direction.

What causes 'Z Channel Pulse Noise Fault Detection' on YASKAWA PG-X3 Controller?
- R
  Rebecca Zavala MDSep 2, 2025
  The 'Z Channel Pulse Noise Fault Detection' error on your YASKAWA Controller is likely due to PG cable noise interference. Separate the PG cable wiring from the source of the noise, such as drive output wiring, to resolve this issue.

What to do if YASKAWA PG-X3 Controller shows 'Control Method Selection Error'?
- T
  Timothy McneilSep 4, 2025
  If your YASKAWA Controller displays a 'Control Method Selection Error', it means the control mode requires a PG option, but no PG encoder is installed (A1-02 = 1, 3, or 7). You can resolve this by: * Connecting a PG option. * Correcting the value set to A1-02.

What to do if YASKAWA Controller shows 'Non-Compatible Option connected to drive port CN5-A'?
- W
  William RoseSep 7, 2025
  If your YASKAWA Controller shows a 'Non-Compatible Option connected to drive port CN5-A' error, it means you've connected an incompatible option. Use only compatible options. Connect PG-X3 to CN5-B or CN5-C. For other option cards, refer to the Installation Manual for that option card.
