The Torque Override Feature

The motor power setpoint is calculated from the riders effort, torque on the crank times the cadence, normally. As the torque curve oszilates during one crank revolution (two sinusoidal half waves) the torque signal is filtered to get a smooth, homogenius assistance. But there may be situations, where you want an immediate response of the motor to the torque on the crank. A sudden sprint to cross a road or to overtake another rider for example. This immediate response can be achieved by the torque override function. You can define a threshold for each assist level. If the torque signal is higher than this threshold and the scaled motor current setpoint from the override feature is higher than the setpoint calculated from the normal riders effort, the torque signal directly sets the motor power. But keep in mind, that this leads to a sinusoidal motor power curve over one crank revolution also.
The higher you set the threshold, the less headroom you have, to modulate the motor power with the torque signal. If you don't want to use this feature, just set the threshold to a bigger value than 3300, then it will never kick in.
