What to do if YASKAWA DC Drives show braking transistor overload fault?
- N
  Noah RossAug 2, 2025
  If you are experiencing a braking transistor overload fault with your YASKAWA DC Drives, it could be due to a high duty cycle of the braking transistor. Consider installing a braking unit (CDBR series). It's also possible that you enabled the protective function for the braking transistor when you have a regenerative converter. In this case, set L8-55 = 0 [Internal DB TransistorProtection = Disable]. If the braking transistor in the drive is broken, replace the drive.

What causes current offset fault in YASKAWA GA800 DC Drives?
- V
  Veronica PhamAug 7, 2025
  If you're experiencing a current offset fault with your YASKAWA DC Drives, it might be because the drive starts operation while the induced voltage stays in the motor. Create a sequence that does not restart operation when induced voltage stays in the motor. It could also be due to a drive hardware problem, in which case you should replace the drive.

What to do if YASKAWA DC Drives motor overheat?
- M
  Mia JuarezAug 13, 2025
  If the YASKAWA DC Drives motor overheats, it could be due to defective thermistor wiring. Correct any wiring errors. It may also be caused by a fault on the machine. In this case, examine the machine and remove the cause of the fault. Also, the motor might have overheated because of the load level, acceleration/deceleration time, and motor start/stop frequency (cycle time). Decrease the load.

Why is my YASKAWA GA800 DC Drives motor overloading?
- B
  bbarronAug 17, 2025
  If the YASKAWA DC Drives motor is experiencing an overload, it could be because the load is too heavy. Try decreasing the load. Also, the acceleration/deceleration times or cycle times may be too short. Examine the acceleration/deceleration times and the motor start/stop frequencies (cycle times). Increase the values set in C1-01 to C1-08 [Acceleration/ Deceleration Times].

Why YASKAWA GA800 DC Drives Bluetooth communication fault?
- M
  Molly WilsonAug 23, 2025
  If you're experiencing Bluetooth communication faults with your YASKAWA DC Drives, it may be because the smartphone or tablet with DriveWizard Mobile installed is too far from the keypad. Use the smartphone or tablet 10 m (32.8 ft) or nearer to the keypad. It could also be that radio waves from a different device are causing interference. Make sure that no device around the keypad uses the same radio bandwidth (2400 MHz to 2480 MHz), and prevent radio interference.
