I'm controlling spindle VFD with C6 board (with reference voltage 0-10V) from
cnc4pc:
http://www.cnc4pc.com/Store/osc/product_info.php?cPath=25&products_id=58
and here is complete setup for running this, and it runs perfectly for me:
setp stepgen.2.position-scale 1
setp stepgen.2.maxvel 18000
setp stepgen.2.steplen 20000
setp stepgen.2.stepspace 0
setp stepgen.2.dirhold 20000
setp stepgen.2.dirsetup 20000
setp stepgen.2.maxaccel 200
# Enable
net spindle-enable <= motion.spindle-on => stepgen.2.enable
# Connect spindle speed to scaler
net spindle-cmd motion.spindle-speed-out => scale.0.in #
# Connect scaler output to stepgen velocity
net spindle-freq <= scale.0.out => stepgen.2.velocity-cmd #
# Connect output to the pin for the analog voltage of cnc4pc board
net spindle-out <= stepgen.2.step => parport.0.pin-14-out #
# Control of spindle on/off over the relay instead of triac
net spindle-fwd motion.spindle-forward => parport.0.pin-16-out
Now what I want is only to connect this with RPM display in pyvcp.
