Throttle control depends of P3 parameter:
• P3 = 1 → speed control: throttle controls the PWM duty_cycle, motor will run up to the max defined speed and up to motor max defined current.
Changing the assist level seems to have no effect.
• P3 = 0 → imitation torque control: throttle controls the speed and the torque/max current of the motor.
Max assist level means that motor will run up to max defined speed and up to motor max defined current. Choosing different assist levels will make the motor running up to fractions of those values.
NOTE: each throttle position seams refer to always the same speed value, where the max throttle position may be equivalent to 72km/h (max defined speed possible on LCD5).
How max current control works
If I block the wheel with my hand, the motor keeps doing force/torque and I can read the current value on the power supply. The current is low at the begin of throttle and increases as I increase the throttle.
The current control, at least while the motor is blocked, must be done using AN8 (motor total current) because phase B current signal may be 0 at that situation.
With the motor blocked, it tries to rotate (doing force/torque) but after some seconds it stops.
