Hello, I am having issue with YAW axis. All other axes work good, with no issues.
Hardware and config info - SteadyGim6 PLUS, board v3.1, FW 2.60 b4 1. Motors: YAW iPower GMB6028-150T, PITCH/ROLL iPower GBM5208H-200T 1. RX input - all off 2. Encoders - mounted (PWM ones) but all disabled for now 3. Follow frame + follow YAW
How issue looks: 1. I turn on gimbal, motors are off - I look on gauges and monitoring tab - everything looks fine 2. Arm motor - then YAW starts to spin crazy, so I turn motors off (or wait for board to do this automatically after few secs) 3. After this, red dot is spinning crazy on YAW gauge, also in monitoring tab I see YAW_ERR floating form quickly form thousands below zero to thousands above zero. All other readings are fine - ACC, GRYO, ERR_PITCH, ERR_ROLL - show real values 4. This is kept until board restart
What "solution" I've found: 1. When I disable ROLL axis - then YAW + PITCH works fine, no issue with YAW axis, red dot (eg. target) is still, so ERR_YAW is 0 2. When I disable PITCH axis - no, it doesn't help, YAW is crazy then too 3. When I disable ROLL+PITCH - it doesn't help! So YAW works goon only together with PITCH, no other combination
After diagnosing points 1 and 2, I would say it's ROLL axis messing (maybe cables interference), but point 3 buried my idea.
Maybe you guys have any idea what else I should check?
After few more hours playing here and there, I've found cause if issue - wrong YAW motor poles count :/ Kill me please, I had 24 set, but motor has 23 actually - find out by auto detection feature. Now everything works good :) No idea why/how YAW worked good together with PITCH with this wrong setting. Anyway, leaving it here, maybe will be helpful for someone.
Hello, Ok. Usually, we recommend checking number of poles in the specification, because auto detection can detect wrong numbers via many reasons. Have a nice day!
