Hello
A friend of mine is rebuilding a Brother TC-221 CNC from the original system to LinuxCNC, he uses the original spindle converter and also the original drivers for the XYZ motors, there are synchronous servo motors. I would like to find out if by any chance someone does not have access to the schematics for the synchronous drivers, as the driver for the X axis has gone wrong. After enabling the motors, the motor starts up to maximum speed and stops, displays an error. LinuxCNC does not ask for any speed. According to the preliminary diagnosis, we determined that the IGBT transistors must have gone, but if I had a diagram, we could verify it 100%.
I will be grateful if someone has a schematic for those synchronous motor drivers.
