Title: No 10v output from pin 8 g540
Post by: timber715 on December 29, 2016, 11:41:30 PM
Good day guys, I have been trying to get my spindle speed controlled under mach3.
First my machine:
Mach3
Gecko G540
ESS from warp9
Platform CNC (From Brian Ottoge)

The Spindle/VFD
FC300 vfd
2.2kw water cooled spindle

I am able to start and turn off the spindle from mach3 (relay wired) but I couldn't get to control the speed from mach3.
From the VFD there is 10v going into the g540 pin 9 (9.6v) but from pin 8 to the vfd there is zero.
Help me please, I am electrically retarded to a point.
