Q : How to fix the “ITE” fault on GD350A-037G/045P-4 VFD used for asynchronous motor speed control?
A: VFD Model: GD350A-037G/045P-4
Application: Asynchronous motor ordinary speed regulation
Fault phenomenon: dozens of VFDs in the same workshop report ITE and cannot be reset.
How to solve it?
Reason analysis:
The main circuit of the static measurement VFD is good. The power transmission display screen reports that ITE cannot be reset, indicating that the fault persists. Disassemble and inspect the current detection circuit on the back of the drive board for black dust.
Solution:
Clean the dust in the current detection circuit with alcohol. Improvement effect: ITE fault is eliminated, and the VFD works normally under load.
