Mitsubishi FR-SGJ Spindle Drive
I have a faulty Mitsubishi FR-SGJ-2-1.5K Spindle Drive, from a Traub TNL16, that’s giving an alarm 24 (main circuit fault).
I've fitted a replacement drive & the machine is OK so I know the problem is on the original drive.
I've visually checked the drive over & there's nothing obviously blown.
Does anyone have a Troubleshooting Manual for this drive they could e-mail me or a link to one?
Thanks
Mike
Mitsubishi FR-SGJ Spindle Drive - Alarm 24
Finally got back to this last week.
I'd swapped the front card, SGJ-CB, with another drive & the fault followed.
Took the card off & just went through the components with a meter doing simple resistance checks, found resistor R61 open circuit (680Kohm 3W).
Got resistors in on Monday, soldered one in & ran the machine on MDI at various speeds for 24hrs & all OK.
It's been back in production since yesterday afternoon & OK so far.
