Why does my Fuji Electric Inverter rollback?
- A
  April HensleyAug 5, 2025
  If your Fuji Electric Inverter experiences rollback, several factors could be responsible. It could be due to insufficient starting frequency, in which case you should increase F23 to a maximum of 1.0 Hz. Another cause might be early brake opening; try increasing L82, setting it to F24 minus the brake reaction time. Insufficient torque could also be the culprit, so increase P06 to be between 30% and 70% of P03. Lastly, you can increase F09 to a maximum of 5.0%.

What to do if my Fuji Electric Inverter hits at starting?
- M
  meyersluisAug 10, 2025
  If your Fuji Electric Inverter is hitting at starting, it could be due to several reasons. The starting frequency might be too high, so reduce F23 to a minimum of 0.1 Hz. Also, the brake might be opening late, so reduce L82 to a minimum of 0.20 s. You may also need to increase F24 to a maximum of 1.5 s. If the torque is too high, reduce P06 to be between 30% and 70% of P03. Finally, check the brake operation, guides (oil, alignment, etc.), and car fixation (shoes).

How to fix rollback on a Fuji Electric Inverter?
- C
  Catherine SteeleAug 14, 2025
  If your Fuji Electric Inverter experiences rollback, it might be due to several reasons. The brake closing might be late, so reduce L83. Also, the DC brake reaction might be too soft, so increase F21 to a maximum of 90% and check if F22 is 0.00s. Insufficient torque could also be a factor, so increase P06 to be between 30% and 70% of P03. Finally, increase F09 to a maximum of 5.0 % and check the security chain and brake operation.

What causes undershoot from high speed to creep speed in a Fuji Electric Inverter?
- D
  derrick28Aug 18, 2025
  If your Fuji Electric Inverter experiences undershoot from high speed to creep speed, consider the following: The slip frequency might be too high, so reduce P12 to a minimum of 0.1 Hz. If the deceleration is too fast, increase the deceleration ramp (i.e. E13) to a maximum of 2.00 s. Also, increase the 2nd S-curve at deceleration (i.e. L25) to a maximum of 50 %. Insufficient torque could also be a factor, so increase P06 to be between 30% and 70% of P03. Lastly, increase F09 to a maximum of 5.0%.

Why does my Fuji Electric FRENIC-Lift FRN0015LM2C-4E hit when stopping?
- C
  Christopher WashingtonAug 23, 2025
  If your Fuji Electric Inverter is hitting at stopping, it could be due to the following reasons: The brake might be closing early, so increase L83 to a maximum of F22 minus the brake reaction time. Also, the DC brake reaction might be too strong, so reduce F21 to a minimum of 50%. If the deceleration ramp is too fast, increase the deceleration ramp (i.e. E15). Finally, check the security chain and brake operation.

How to troubleshoot vibration at constant speed in a Fuji Electric FRENIC-Lift FRN0015LM2C-4E Inverter?
- G
  gomezlaurenAug 27, 2025
  If your Fuji Electric Inverter is vibrating at a constant speed, it could be due to several reasons. The torque might be too high, so decrease P06 to be between 30% and 70% of P03. Also, the HIGH speed might be too fast, so reduce the HIGH speed (i.e. C11) and set the motor's rated speed instead of the motor's synchronous speed. Finally, check the guides (oil, alignment, etc.), car fixation (shoes), motor connection, and motor gearbox.

How do I fix landing accuracy issues on my Fuji Electric FRENIC-Lift FRN0015LM2C-4E Inverter?
- B
  Blake KnightAug 31, 2025
  If your Fuji Electric Inverter's landing accuracy is affected by the load, it could be due to an incorrect slip frequency. To resolve this, perform auto-tuning (P04=2).
