What to do if the LED display is not on for Inovance Controller?
- G
  Gary WrightAug 19, 2025
  If the LED display of your Inovance Controller is not on or doesn't show "rdy", it could be due to several reasons. First, the control power voltage might be abnormal, so measure the AC voltage between L1C and L2C. Second, the main power voltage might be abnormal; for a single-phase 220 V model, measure the AC voltage between L1 and L2. If the DC bus voltage amplitude (voltage between P and -) is lower than 200 V, "nrd" will be displayed. Third, the program burning terminal might be shorted, so check it. Finally, the servo drive itself might be faulty.

Why is the shaft of my Inovance Controller's servo motor in free running status?
- R
  Roberta MartinezAug 21, 2025
  If the shaft of your servo motor is in a free running status, ensure the S-ON signal is valid by setting the operation panel to servo status display and checking if it displays "rdy" instead of "run". Also, verify that the control mode selection is correct by checking if H02-00 is set to 1.

Why doesn't the servo motor rotate in my Inovance Controller?
- R
  Rebekah GrahamAug 25, 2025
  If your Inovance Controller's servo motor does not rotate, it could be due to an internal torque reference (H0B-02) being 0. Check whether the polarity of the input signal is reversed.

Why is my Inovance Controller's servo motor rotating in the reverse direction?
- T
  Tyler WoodAug 26, 2025
  If the servo motor of your Inovance Controller rotates in the reverse direction, and you're using AI to input torque reference, check whether the polarity of the external voltage input signal is reversed, as the internal torque reference (H0B-02) might be negative.

What causes the servo motor of Inovance Controller to not rotate or have abnormal speed?
- L
  Lauren Myers MDAug 28, 2025
  If the servo motor does not rotate or the motor speed is abnormal, it might be caused by incorrect AI wiring. Verify that the analog input channel is selected correctly and that the selected AI terminal is wired correctly.

How to fix unsteady motor speed on Inovance Controller?
- E
  Ethan WebsterAug 30, 2025
  If the motor speed of your Inovance Controller is not steady, perform automatic gain tuning, as the gain might be set improperly.

What causes the motor shaft to vibrate left and right on Inovance Controller?
- A
  Anthony GarnerSep 2, 2025
  If the motor shaft vibrates left and right, it might be because the load inertia ratio (H08-15) is too large. Perform inertia auto-tuning and automatic gain tuning on your Inovance Controller.

What to do if the servo motor of Inovance Controller does not rotate?
- C
  Charles WallsSep 4, 2025
  If your Inovance Controller's servo motor does not rotate, it could be due to the input reference pulse counter (H0B-13) being 0. Check whether the high/low-speed pulse input terminal is wired correctly. Alternatively, it could be that the position reference is not input. Check whether FunIN.13: INHIBIT (pulse input forbidden) or FunIN.37: PulseInhibit (pulse forbidden) is used.

Why does my Inovance Controller's servo motor jitter at low speed?
- B
  Brian KnightSep 6, 2025
  If your Inovance Controller's servo motor jitters at low speed, it might be because the motor speed is not steady. The gain may be set improperly.
