CSMIO/IP-M and PM752 Drivers

[JAZZCNC]

. In fact I'd say the machine seems smoother than before, but that could just be placebo..

No It's not placebo affect.! . . That's the difference between a quality controller and a cheaper controller, esp if combined with decent Digital drives. Don't be surprised if able tune motors higher.

.Now to get the VFD/Spindle wired, which I think is shown on Dean's diagram on the other thread (ACM and VI to the analog 10V output) and then work out the VFD settings to change to go from RS485 to external control.

If it's a Huanyang VFD then the parameters for External control are.!

PD 01 = 1 (External Frequency) - - - - - IP/M Analog connections Pin1 = VI Pin2 = ACM
PD 02 = 1 (External Start/Stop) - - - - - -IP/M Relay OUTPUTS Pin 12 = FOR Pin 25 = DCM ( In Mach3 Set OUTPUT #1 = port 10 Pin 4 not sure if same in Mach4 don't use it.)

There are other parameters to set for things like diplaying correct RPM etc but can't remember them off top my head but have them wrote down at work so if get stuck just shout.
