PM-25MV speed control

[mcham]

Does anyone have a solution to controlling the spindle of a Precision Matthews PM25mv? It has a BLDC system controlled by a pot. I don't think it is safe to just hook it up without electrical isolation. It would also need to involve some relays to enable and control forward/reverse.

Thanks guys!

Those type of drives are not designed for CNC interface and you are right they also need isolation for control. On/off can be done via a relay but RPM control will need some more electronics such as optical isolators.

Can Masso control spindle speed with PWM or only 0-10V?

Please goto the F1-Setup screen and in the spindle settings you can set spindle control to PWM, you can also set your PWM frequency.
