Vesc faults when there is load

Hello, i builded a custom vesc 6 board. I'm trying to setup my 1000W Hub motor for ebike. It seems all ok but when i try to get on the bike, if i turn the throttle too fast ( in reality if i turn it in a normal way) my motor do a jerk and stops to push.

My fault code is the following:

Fault            : FAULT_CODE_BOOTING_FROM_WATCHDOG_RESET
Motor            : 1
Current          : -0.0
Current filtered : -0.0
Voltage          : 48.45
Duty             : 0.000
RPM              : -0.0
Tacho            : -1
Cycles running   : 0
TIM duty         : 0
TIM val samp     : 3360
TIM current samp : 3360
TIM top          : 6720
Comm step        : 0
Temperature      : 40.89

And when it spins without loads, over 15000 ERPM it returns the fault

Fault            : FAULT_CODE_UNBALANCED_CURRENTS
Motor            : 1
Current          : -1.5
Current filtered : -1.0
Voltage          : 48.01
Duty             : 0.893
RPM              : 14918.8
Tacho            : 42436
Cycles running   : 439888
TIM duty         : 6000
TIM val samp     : 3360
TIM current samp : 3360
TIM top          : 6720
Comm step        : 0
Temperature      : 39.18

Maybe the last is reasonable because it spins at the limit. But what about the first fault?

Unbalanced currents means just that. Likely something wrong with your current sensor circuits.

You provide zero details about your hardware, so don't expect getting any advice beyond wild guesses.
