I tried all 48 patterns twice. Obtained result - nothing... I tested by setting pattern value in HAL file, saving file, starting EMC and pressing F1 and F2. I understand that at this moment motor should turn. Is that correct? Here is the contents of HAL file that relates to that particular instance of encoder, bldc module and 3pwmgen. loadrt bldc cfg=qh,qh,qh addf bldc.2 servo-thread newsig emcmot.02.enable bit sets emcmot.02.enable FALSE net emcmot.02.enable => hm2_[HOSTMOT2](BOARD).0.3pwmgen.02.enable net emcmot.02.enable <= axis.2.amp-enable-out # encoder feedback setp hm2_[HOSTMOT2](BOARD).0.encoder.02.counter-mode 0 setp hm2_[HOSTMOT2](BOARD).0.encoder.02.filter 1 setp hm2_[HOSTMOT2](BOARD).0.encoder.02.index-invert 0 setp hm2_[HOSTMOT2](BOARD).0.encoder.02.index-mask 0 setp hm2_[HOSTMOT2](BOARD).0.encoder.02.index-mask-invert 0 setp hm2_[HOSTMOT2](BOARD).0.encoder.02.scale [AXIS_2]INPUT_SCALE setp bldc.2.scale [AXIS_2]INPUT_SCALE setp bldc.2.poles 8 setp bldc.2.pattern 47 net motor.2.hall-1 hm2_[HOSTMOT2](BOARD).0.gpio.027.in => bldc.2.hall1 net motor.2.hall-2 hm2_[HOSTMOT2](BOARD).0.gpio.028.in => bldc.2.hall2 net motor.2.hall-3 hm2_[HOSTMOT2](BOARD).0.gpio.029.in => bldc.2.hall3 net enc.2.raw hm2_[HOSTMOT2](BOARD).0.encoder.02.rawcounts => bldc.2.rawcounts setp hm2_[HOSTMOT2](BOARD).0.3pwmgen.02.scale 166.667 setp bldc.2.value 10 net pwm.02-a bldc.2.A-value => hm2_[HOSTMOT2](BOARD).0.3pwmgen.02.A-value net pwm.02-b bldc.2.B-value => hm2_[HOSTMOT2](BOARD).0.3pwmgen.02.B-value net pwm.02-c bldc.2.C-value => hm2_[HOSTMOT2](BOARD).0.3pwmgen.02.C-value 7i39 does receive power. It has 28.2VDC on motor power input terminals. Encoder is working - when I turn motor by hand, joint's position changes and bldc.2.rawcounts also changes. Hall sensor feedback also is recieved - when I watch bldc.2.hall1, bldc.2.hall2 and bldc.2.hall3 pins in HAL Config, all 3 LEDs change colors as I turn motor by hand.
