Hello we purchased a used Hurco
After some time the spindle started throwing errors
This machine has the yaskawa drives
The spindle drive is CIMR-VMW20110-Mxxx with the 2 windings selection
and the fault is F100 (overcurrent). And it seems that it does the overcurrent because at the monitoring of the current at c1-06 parameter of the drive it exceeds the normal current (over 200amps)
We checked the motor and cables with an insulation tester and seems to be alright
We also sent to a local electronics repair shop the drive and they did not find something obvious
Also the encoder feedback seems to be steady when it works and working even when you rotate the spindle by hand

Has anyone experienced something similar or have some suggestion to check something?
Or to suggest a repair shop which repairs or checks cnc drives in europe?
We are based in Greece

Thank you in advance
