What causes Ground Fault GF on YASKAWA A1000?
- C
  Carol RuizSep 1, 2025
  If the YASKAWA Controller displays a Ground Fault (GF) error, it indicates that ground leakage current has exceeded 50% of the drive's rated output current, cable or motor insulation is broken, or there's excessive stray capacitance at the drive output. To fix it, check the output wiring and motor for short circuits or broken insulation, replace any damaged parts, and reduce the carrier frequency.

What to do if my YASKAWA Controller shows an Overcurrent oC error?
- D
  Deborah RobertsAug 25, 2025
  If your YASKAWA Controller displays an Overcurrent (oC) error, it usually means there's a short circuit or ground fault on the drive output side, the load is too heavy, acceleration/deceleration times are too short, motor data or V/f pattern settings are incorrect, or a magnetic contactor was switched at the output. First, check the output wiring and motor for short circuits or broken insulation, replacing any faulty components. Next, inspect the machine for mechanical damage and repair as needed. After that, verify the drive parameter settings and check the output contactor sequence.

What does Er-04 mean on my YASKAWA Controller?
- L
  Laurie WrightAug 30, 2025
  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.
L

What does Er-12 error mean on YASKAWA A1000 Controller?
- T
  tcoxSep 14, 2025
  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.
N
Nicole PhillipsSep 9, 2025
What does End5 mean on my YASKAWA A1000?
- S
  Sally RiceSep 9, 2025
  The YASKAWA Controller End5 error indicates a Resistance Tuning Error, meaning the calculated resistance value is outside the allowable range. Double-check the data entered for the Auto-Tuning process and check the motor and motor cable connections for faults.

What causes a DC Undervoltage Uv1 error on my YASKAWA A1000 Controller?
- J
  Jonathan WoodAug 27, 2025
  The YASKAWA Controller DC Undervoltage (Uv1) error appears when the voltage in the DC bus falls below the undervoltage detection level (L2-05). This can occur due to a power supply failure, loss of an input phase, or an inadequate power supply. Check the power supply to ensure it is strong enough.
