How to solve Control Method Selection Error in YASKAWA Recording Equipment?
A Control Method Selection Error in YASKAWA Recording Equipment typically occurs because the control mode requires a PG option, but no PG encoder is installed (A1-02 = 1, 3, or 7). To resolve this, connect a PG option or correct the value set to A1-02.
What does End7 error mean on YASKAWA A1000 Controller?
If the YASKAWA Controller displays an End7 error, it indicates a No-Load Current Alarm, meaning the entered no-load current value was outside the allowable range, or Auto-Tuning results were less than 5% of the motor rated current. To resolve this, check and correct faulty motor wiring and double-check the data that was entered for the Auto-Tuning process.
How to resolve Heatsink Overheat oH or oH1 error on YASKAWA A1000?
If the YASKAWA Controller displays a Heatsink Overheat (oH or oH1) error, it means the surrounding temperature is too high, the cooling fan has stopped, the heatsink is dirty, or the airflow to the heatsink is restricted. To resolve this, check the surrounding temperature and install cooling devices if needed, inspect the drive cooling fan, clean the heatsink, and ensure proper airflow around the heatsink.
What does Er-04 mean on my YASKAWA Controller?
The YASKAWA Controller Er-04 error indicates a resistance fault. This could be due to wrong input data, auto-tuning exceeding the given time frame, or calculated values being out of range. Check the input data and wiring, then re-enter the data and repeat the Auto-Tuning.
What does Er-13 mean on my YASKAWA Controller?
The YASKAWA Controller Er-13 error indicates a leakage inductance error, meaning the drive was unable to complete tuning for leakage inductance within 300 seconds. Check all wiring and correct any mistakes. Double-check the motor rated current value entered into T1-04 for Auto-Tuning against the motor nameplate, and enter the correct value.
What does Er-11 mean on my YASKAWA A1000 Controller?
The YASKAWA Controller Er-11 error indicates a motor speed fault, suggesting the torque reference was too high. Increase the acceleration time (C1-01). If possible, disconnect the load.
What does Er-03 mean on my YASKAWA A1000 Controller?
The YASKAWA Controller Er-03 error indicates that the STOP button was pressed and Auto-Tuning was canceled. Repeat the Auto-Tuning.
What does Er-01 mean on my YASKAWA A1000 Controller?
The YASKAWA Controller Er-01 error indicates a motor data fault, meaning the input motor data are not valid (e.g., the base frequency and base speed do not fit). Re-enter the data and repeat Auto-Tuning.
What to do if YASKAWA Recording Equipment shows PG disconnected?
If your YASKAWA Recording Equipment indicates that the PG is disconnected, the issue might stem from a disconnected PG cable. Try reconnecting the cable. It could also be due to incorrect PG cable wiring, which needs to be corrected. Insufficient power to the PG encoder or a brake holding the PG could also be the cause. Make sure the correct power supply is properly connected to the PG encoder and ensure the brake releases properly.
What does Er-12 error mean on YASKAWA A1000 Controller?
If the YASKAWA Controller displays an Er-12 error, it indicates a current detection error which could be due to one or all output phases being lost, current being too low or exceeding the drive's rating, or faulty current sensors. To resolve this, check the wiring, ensure the drive rating fits the motor, check the load (Auto-Tuning should be performed without the load connected), and replace the drive if necessary.
