How to fix Fuji Electric Inverter rollback?
- J
  Jerry PowellAug 13, 2025
  If your Fuji Electric Inverter experiences rollback, it could be due to several reasons. It might be caused by insufficient starting frequency, so try increasing F23 to a maximum of 1.0 Hz. Another cause could be early brake opening, in that case increase L82, setting it to F24 minus the brake reaction time. Insufficient torque can also cause this, so increase P06 to 30-70% of P03. Finally, increasing F09 to a maximum of 5.0% may also help.

What to do if Fuji Electric Inverter 'hits' at starting?
- K
  Keith PattersonAug 17, 2025
  If your Fuji Electric Inverter 'hits' at starting, it could be due to several reasons. A too high starting frequency might be the cause, so reduce F23 to a minimum of 0.1 Hz. Also, late brake opening could be the reason, so reduce L82 to a minimum of 0.20 s. Increasing F24 to a maximum of 1.5 s might also help. If the torque is too high, reduce P06 to 30-70% of P03. Finally, check the brake operation, guides (oil, alignment, etc.), and car fixation (shoes).

Why does my Fuji Electric Inverter undershoot from high speed to creep speed?
- H
  Hailey YoungAug 21, 2025
  If your Fuji Electric Inverter experiences undershoot when transitioning from high speed to creep speed, several factors could be responsible. One potential cause is a slip frequency that's too high; try reducing P12 to a minimum of 0.1 Hz. Another factor could be a deceleration rate that's too fast, so increase the deceleration ramp (i.e., E13) to a maximum of 2.00 s. Also, consider increasing the 2nd S-curve at deceleration (i.e., L25) to a maximum of 50%. Insufficient torque can also contribute, so increase P06 to be within 30-70% of P03. Lastly, increasing F09 to a maximum of 5.0% may also help resolve this issue.

How to solve 'hit' at stopping with Fuji Electric Inverter?
- R
  Rachel JohnsonAug 26, 2025
  If your Fuji Electric Inverter 'hits' at stopping, it could be due to several reasons. Early brake closing might be the cause, so increase L83 to a maximum of F22 minus the brake reaction time. If the DC brake reaction is too strong, reduce F21 to a minimum of 50%. A deceleration ramp that's too fast can also cause this, so increase the deceleration ramp (i.e., E15), keeping in mind that the maximum value depends on the lift magnets. Finally, check the security chain and brake operation.

Why is my Fuji Electric Inverter vibrating at constant speed?
- S
  simslaurenAug 29, 2025
  If your Fuji Electric Inverter is vibrating at a constant speed, the issue might stem from several factors. If the torque is too high, decrease P06, setting it to 30-70% of P03. Additionally, if the HIGH speed is too fast, reduce the HIGH speed (i.e. C11), setting 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.

What causes rollback in Fuji Electric Inverter?
- T
  Tristan BrownSep 1, 2025
  If your Fuji Electric Inverter experiences rollback, late brake closing could be the reason, so reduce L83. Also, if the DC brake reaction is too soft, increase F21 to a maximum of 90% and check if F22 is 0.00s. Insufficient torque can also cause this, so increase P06 to 30~70% of P03. Finally, check the security chain operation (EN signal) and brake operation.

Why is landing accuracy of my Fuji Electric Inverter affected by the load?
- J
  Jamie BlanchardSep 5, 2025
  If the landing accuracy of your Fuji Electric Inverter is affected by the load, it could be due to an incorrect slip frequency; in this case, perform Auto tuning (P04=2). If you have different landing accuracy (braking, driving), and stopping is too early in driving mode, increase P09. If stopping is too late in driving mode, decrease P09. Also, insufficient torque can cause this, so increase P06 to 30~70% of P03.

What should I do if my Fuji Electric Inverter rolls back?
- T
  Tracy GilbertSep 9, 2025
  If your Fuji Electric Inverter rolls back, it could be due to late brake closing, so reduce L83. If the motor current is removed too early, check that the EN signal remains active until the brake is closed. If this does not help, increase H67. If the issue persists, adjust the ASR gain and time at CREEP speed: for PMSM, add 1.0 to the current value of L38 and subtract 0.050 from the current value of L39. For IM, add 10.0 to the current value of L38 and subtract 0.050 from the current value of L39.
