Hello All;

I’m stumped, and would sure appreciate it if one of you would review the information below and tell me what bonehead thing I have done or neglected to do to get my DIY CNC Router running.

The only problem I am having, is the configuration of the spindle;

M3 and M5 commands in Mach3 do turn the spindle On and Off as they should.
“S” commands in Mach3 do adjust the spindle speed. ( Not Properly ).
The problem;

7200 RPM is as slow as the spindle will run regardless of “S” value commanded. The Chart below shows the actual results that I am seeing from various “S” commands.
From the results, I surmise that the C10 and C6 boards are wired correctly, as well as operating correctly and that Mach3 is configured and working correctly. My thinking is that I have missed something in the parameter settings of the VFD, but four weeks of head scratching and trying different things has not helped me solve the problem.

Software:
Windows XP Professional
Mach 3 Ver. 2

Hardware:
CNC4PC C10 Breakout Board
CNC4PC C6 Spindle Speed Control Board
Huanyang VFD [ Model: HY02D223B ]
2.2Kw Water Cooled Spindle


Electrical Connections:

C10 Breakout Board to C6 Spindle Speed Control Board

C10 Board Pin 1 to C6 Board EN CCW Relay 1
C10 Board GND to C6 GND at inputs
C10 Board Pin 14 to C6 Step at inputs
C10 Board Pin 16 to C6 DIR CW Relay 2

C6 Spindle Speed Control Board to VFD

C6 Board Output 0-10 v to VI on VFD
C6 Board Output GND to ACM on VFD
C6 Board EN / CCW1 / NO to FOR on VFD
C6 Board DRV / CCW1 / NO to REV on VFD
C6 Board V_IN1 to DCM on VFD
C6 Board V_IN2 to DCM on VFD
