Can't get 2.2KW spindle to work
« on: June 04, 2013, 02:11:22 PM »
 ::) Hi All,
New ESS installation. Router axis and homing work, the spindle doesn't. It's connected from BOB to C41 spindle control board and to Sunfar 300 VFD. Speed/direction command goes to C41 (relay comes on) VFD says it's running, but no RPM. Measured for dc volt across the analog out pins, no voltage. I tried every settings  nothing brings the spindle alive. It worked before the retrofit. Desperately need help.

Have you set the ESS config to the correct spindle output method?

I don't know any more Hood. I tried every combination there is, accept probably the right ones. Please see the screenshut and the latest XML file

Just had a quick look at the C41 and it is PWM, your SS config above is not PWM, you have it set Step/Dir.

Now I'm confused. I do have it set for Step/Dir. What about setting the Spindle in Ports and Pins? Do I have to set that also to Step/Dir?
I have the C41 jumper on international mode, because the VFD only has a FWD terminal only, no REV. I would like you to tell me if the C41 and the VFD is wired correctly. I'm attaching a jpg on how I wired it, and a picture of the C41 card.

The C41 manual seems to contradict itself, one minute is saying to set Mach Spindle Setup page to Step/Dir then right below that it shows a screenshot of it set as PWM and it shows a base frequency being set of 200.

What I would try is go to the ESS config, set the Spindle control method to PWM and set a base frequ of 200 in there and see if you get anything.

sorry to interject, and correct me if I'm wrong but it looks like he has it set for analog speed control PWM output is kitty corner on the board

Not really sure what you are meaning, never used any CNC4PC stuff but I would imagine all spindle controllers output 0-10v or similar. The input method can be different. This board uses a PWM signal which it gets from Mach, some boards use a step signal but all I think convert that to an analogue output voltage.
Maybe I am seeing things wrong however :)

I think I see what you are saying now :) By "kitty corner" I presume that is USA parlance for opposite corner :)
The PWM at the opposite corner is the Input signal, ie the signal that it gets from Mach, that signal is then converted to an analogue voltage which is output at the opp... wait a second, the kitty corner :)
