5.6 Throttle and Regen Voltage Maps
Advanced Setup tab
With most ebike controllers, the throttle signal controls the effective voltage and
hence unloaded rpm of the motor. With a
Frankenrunner , however, the throttle is
directly controlling the motor torque.
If you pick the motor off the ground and give it just a tiny amount of throttle, it will
still spin up to full rpm as there is no load on the motor. People sometimes
mistake this behavior as an all-or-nothing throttle response. If you apply partial
throttle
while riding , you will get a proportional torque from the motor which will
stay constant even as the vehicle speeds up or slows down. This is different from
standard ebike controllers, where the throttle more directly controls motor speed.
By default, the Frankenrunner is configured so that active throttle starts at 1.2V,
and full throttle is reached at 3.5V, which is broadly compatible with Hall Effect
ebike throttles. The same signal for the throttle is also used to control
regenerative braking (see Section 6.1 Signal Mapping).
The regen voltage is mapped by default so that regenerative braking starts at
0.8V and reaches maximum intensity at 0.0V. This way there is no overlap
between the throttle region and the braking region and a single wire can control
both ranges.
