Repair Steps & Checklist
Click steps to track your progress.
- 1
Verify external wiring for all analog input and output signals connected to the drive, checking for integrity and shielding.
- 2
Measure the actual analog input signal voltage/current directly at the drive's input terminals to confirm it is within specification and free from excessive noise.
- 3
Check drive parameters related to analog input configuration, scaling, offset, and filtering (e.g., A1-xx parameters) for correct settings.
- 4
Inspect the control terminal block and associated connections for any signs of loose terminals, corrosion, or contamination.
- 5
Verify the grounding integrity of the drive, control circuits, and connected analog sensors.
