How do I troubleshoot an Inovance Controller if the LED display is off or doesn't show "rdy"?
- K
  Katie YoungSep 12, 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.

  If the motor speed of your Inovance Controller is not steady, perform automatic gain tuning, as the gain might be set unreasonably.

Why does the motor shaft of my Inovance Controller vibrate left and right?
- A
  April FisherSep 15, 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.
