Bridgeport Heidenhain TNC155 - spindle motor not working.

[BigRalph]

Hello.
After relocation these machine, spindle motor not working.
Motor driver type is: FAC-1R KTK.
After command start - relays snapping and notting happens with motor.
Motor is OK, tacho voltage backing to drive and are OK, every fuses and overcurrent protection OK.
I'm not have schematic diagram of spindle motor driver.
If somebody has schematic diagram pls send me to : lombardchelmek@wp.pl

This is old machine, but is it in good condition - like brand new. I want to repair my machine.

Any solution?

THX
Best regards.
Ralph

Is the potentiometer for spindle ok? And not set for 0?
Is the spindle controlled by driver, or just on/off controll?
Is there any speed controll on spindle motor?

Hi,
Potentiometer is OK.
I check voltage from plc to drive. Voltage is in range 0 ~ 10 volt depend to speed spindle Sxxxx parameter and potentiometer position.
