Hi all,
maybe someone could help or can be helped in the future...
my problem is an undocumented fault: in gdtools "firmware" fault register
on leds: green and blue on still and red blinking, braking on.
this fault is raised at every power up or reset, just after motor pole alignement, and also more or less often while running (from each ten seconds to ten minutes).
fault cannot be cleared by external switch (only got 1 switch on opto_in_2 setup as disable in, clearfault and user_bit_status).
when i clear fault in gdtools, all is working for a while ( test motor config, torque step response and even pwm_in).
my config:
torque mode,
pwm input on opto_in_1,
1 switch on opto in 2 setup as disable in, clearfault and user_bit_status,
opto_in1-, opto_in2- and com hardwired together,
no shared pins between spi and com except GND.
logic 12v, tested 3#, from wall adapter to high quality computer PSU.
HV 25v: big n heavy lab PSU 60V 30A +12000µF 63V + 3 parallel 1N4002 +self.
motor
tiny yaskawa SGMGH 30, 4poles pair (8poles) ,0.4R ,12.5mS electrical time constant (so 4.8mH theorically i think) 200V 22.8A continuous 56A peak
encoder absolute 5V TTL single ended, no index
pwm frequency set at 20kHz limited to +- 80% on each side, update rate 1ms
some of my attempts:
12v logic + 25v + spi : firmware fault as on screen capture
12v logic + spi : drive waits for motor initialisation, status flags "follow error recovery" and "enabled" on. green off, blue and red blinking;
when 25V on, init then flags as screen capture, leds green and blue on, red blinking.
when fault cleared in gdtool, all up and running, device status as on screencap, fault register empty.
12v logic + COM from controler : init, then leds green and blue on, red blinking. cannot go further.
12v + 25v, no motor nor encoder, drive says initialisation fault (luckilly).
i tryed to to re-flash drive, but didn't change anything
also tested at HV from 15 to 45v ... not better
init without encoder plugged ... idem
etc...
i don't know what to do more. it's a pitty as drive, when working, is a damn good stuff!
to follow, pictures and logs
