Hi,
I’m looking for the circuit diagram for the spindle motor drive board. Having intermittent problems with motor whereby occasionally it makes a strange twanging noise with a glitch in high current demand. 
Any help very much appreciated.

Hi Geoff,
Have you tried the motor brushes to see if they are worn or sticking.
Brush problems are quite common in permanent magnet motors.
The unworn brush length is mentioned in the maintenance manual in the files section.
