Hello everyone. I have been lurking here for a while but cant seems to find anything fully related to my problem.
Setup:
Space Cell
2 R-spec Motors
2 VESC (Updated to 2.15)
I have tweaked all the settings to the VESC per data from this forum. Currently running in CANBUS. PPM mode, current no reverse with brake
Problem:
When I go from full throttle to full hard brake, the motors will cut out and only the (slave) VESC will have a blinking red light. If I wait a few seconds for everything to settle, I can throttle again with no issue. Slow braking does not cause an issue.
I am having this issue with dual carvon’s/ space cell 4… Settings are as follows:
motor max: 30a
Motor min: -30
bat max: 20a
batt min: -8a
abs max: 65a
I have one board with these settings and 97mm wheels that works fine, this board has 90mm wheels. Anyone think the wheel size could make a difference? Anyone have any suggestions?
I am using FOC… Does anyone really use BLDC??? Can’t really check for faults because the vesc’s only cut out for a second, they are fine by the time I get home…
I’d say most people use BLDC, myself included. I’ll never use FOC until the VESC 6 as I’m not comfortable risking a $170 speed controller and potentially my life since I live in a place with a lot of hills.
Why can’t you check for faults? When they cut out they might be generating a fault. Just go home, plug it in, check for faults in BLDC tool. Just make sure you don’t turn it off in the time between.
