I looked at the manual online and all the inputs to board corresponded to my pcb. But unlike manual schematic there are no fuses placed next to board. Still it looks like the same controller.
> If the motor checks out okay, the speed controller may be the problem. I ran the motor from a variable voltage lab bench ps I have. It only puts out 20v dc at max, but that turned the motor ok but slowly and the speed varied with voltage. Also at this speed motor was drawing a very small current. So I am now assuming that the fault is not with the motor. Having said that I am still leaning towards the 3phase option. I quite like the idea of the control box not being on the mill head and would prefer to place controller on the wall near to the mill and then control it from a remote pendant. Thanks also for the info on vfd's. I have a cheap one controlling a machine I made. I need to buy a more expensive one to handle the serial / modbus connection. Having read the manual, I know that on the vfd I have I would have to keep manually changing input mode on the vfd to switch between pendant and serial input. I was hoping that I could do this via an external switch or something similar on a different model.
