Problem: After setting up my board I went to test it and found that under load (standing on the board) the motor jitters and has trouble starting. When not under load it spins just fine.
Steps I’ve taken:
- Upgraded the VESC firmware.
- Ran through the motor setup wizard successfully.
- Ran through the input wizard successfully.
Parameters in VESC tool BLDC Mode Motor Current Max: 80A Motor Current Max Brake: -60A Absolute Max Current: 100A Battery Current Max: 50A Battery Current Max Regen: -10A Max ERPM: 100,000 Max ERPM Reverse: -100,000 ERPM Limit Start: 80%
D 0.20 I 3.00A w 5000 RPM P 0.00 degrees IB 3.00 A HB 3.00 A
I’ve read other threads on here and tried some of the suggestions. Nothing thus far has helped. This morning I did change one parameter that seemed to help quite a bit, but wasn’t sure it’s the RIGHT thing to change.
On the General Menu, Advanced Tab I changed Minimum Duty Cycle from 0.5% to 2.0% which seems to have made a difference (at least with bench testing, haven’t ridden yet).
Thanks in advance for any help/suggestions.
