How to fix speed deviation on YASKAWA pg-b3?
- C
  Christine HuffmanJul 31, 2025
  If the YASKAWA Controller experiences speed deviation in control mode with PG, consider the following: * If the load is too heavy, reduce it. * If acceleration and deceleration times are too short, increase them using parameters C1-01 through C1-08. * If the load is locked, check the machine. * If parameters are set inappropriately, check F1-10 and F1-11 settings. * Ensure the motor brake releases properly.

What to do if YASKAWA pg-b3 Controller shows overspeed?
- F
  Frank ChapmanAug 4, 2025
  If the YASKAWA Controller shows an overspeed error: * If overshoot occurs, increase the setting for C5-01 (Speed Control Proportional Gain 1) and reduce C5-02 (Speed Control Integral Time 1). Adjust the input signal using parameters H6-02 through H6-05. You can also enable Feed Forward Control and perform Inertia Auto-Tuning in CLV. * If the speed feedback scaling is incorrect when terminal RP is used as speed feedback input in V/f control, set H6-02 to the value of the speed feedback signal frequency when the motor runs at the maximum speed. * If parameter settings are inappropriate, check the setting for the overspeed detection level and the overspeed detection time (F1-08 and F1-09).

How to resolve Z Channel Pulse Noise Fault Detection on YASKAWA pg-b3?
- B
  Brian HuberAug 8, 2025
  If the YASKAWA Controller detects Z Channel Pulse Noise Fault: * Separate the PG encoder cable wiring from the source of the electrical interference (e.g., drive output wiring). * Make sure the PG encoder is properly wired or is not disconnected and all shielded lines are properly grounded. * Confirm that the PG encoder is properly connected and all shielded lines are properly grounded. Cycle power. Replace the PG option card or the PG encoder if the problem continues after cycling power.

How do I fix a Control Method Selection Error on my YASKAWA pg-b3?
- M
  Michael WilliamsonAug 17, 2025
  If the YASKAWA Controller gives a 'Control Method Selection Error' message, it means the control method requires a PG option, but none is installed. To resolve this: * Connect a PG option. * Correct the value set to A1-02.
