What causes Control Fault (CF) in YASKAWA DC Drives and how to resolve it?
- N
  Nicole JacksonAug 18, 2025
  The Control Fault (CF) error in YASKAWA DC Drives occurs when the torque limit is reached during deceleration for longer than 3 seconds, and the load inertia is too big, the torque limit is too low, or the motor parameters are set incorrectly. To resolve this: * Check the load. * Set the torque limit to the most appropriate setting (L7-01 through L7-04). * Check the motor parameters settings.

How to troubleshoot Heatsink Overheat (oH) error in YASKAWA DC Drives?
- C
  Catherine McdonaldAug 20, 2025
  If your YASKAWA DC Drives are showing 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. You should: * Check the surrounding temperature and install cooling devices if necessary. * Check the drive cooling fan. * Clean the heatsink. * Check the airflow around the heatsink.

What does IGBT Short Circuit (SC) mean on YASKAWA DC Drives and how can I fix it?
- R
  Rhonda JamesAug 23, 2025
  If you're seeing an IGBT Short Circuit (SC) error on your YASKAWA DC Drives, it could be due to motor damage from overheating or insulation failure, a shorted or grounded motor cable, or damage to the drive itself. To troubleshoot: * Check the insulation resistance. * Inspect the motor wiring. Turn the power supply off and then on again to check operation. * Check the drive output side short circuit for broken output transistor. Contact your YASKAWA representative or nearest YASKAWA sales office.

How to troubleshoot Output Phase Loss (LF) error on YASKAWA DC Drives?
- B
  Brandi SilvaAug 26, 2025
  If your YASKAWA DC Drives display an Output Phase Loss (LF) error, it may be due to a disconnected output cable, damaged motor winding, loose drive output wires, or a motor that is too small (less than 5% of drive current). To fix it: * Check the power supply. * Make sure that all cables are properly connected to the correct terminals.
