Increase scale allow me to found some point with 0v output for 0RPM resulting other value also affected (i think this is possible to tune the controller for make correct speed in both direction)
with PWM_PERIOD = 20000000 PWM_OUTPUT_SCALE = 121 isolator Zero to minimum at full reverse (-55 on "motion.spindle-speed-out-rps") the "offset.pwmgen.out" pin is at 0, and your PWM is at ~0%, or~1.1v output -10.2v at 0 speed (0 on "motion.spindle-speed-out-rps") the "offset.pwmgen.out" pin is at 55, and your PWM is at ~50% or~12.9v output 0/-0.01v at full forward(55 on "motion.spindle-speed-out-rps") the "offset.pwmgen.out" pin is at 110, and your PWM is at ~100% or~22.8 output 8.6v Thanks for the suggestion about testing other output pin !! -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
