Yes the green board.
It's not unusual for some speed controlers to use 0-5V and the Pmdx 107 has this feature if required. However It's more common to use 0-10V.
The Lenze controller can obviously use either.
Agnd on pmdx 107 goes to 0v and Aout to 10V. By default the 107 outputs 0-10v so If you want to use 5V the set the Dip switches on the 107 board to output 5v.
If you want to test this with crude setup then put a 1.5Vdc battery between 0v and 10v. (Or 0-5v spindle will just spin faster thats all)
Then find the enable pins and put a NO switch on them to toggle ON/OFF.
(Warning don't do any of this wiring live has the speed controller could be at mains potential)Last edited by JAZZCNC; 21-10-2015 at 08:37 AM.
