Baserunner V6 User Manual

The controller then rotates this field faster and faster until reaching the “Autostart
Max RPM” value.
As initial values, set the “Autostart Injection Current” to 50-80% of your maximum
phase current, an “Autostart Max RPM” between 5% to 10% of the running motor
rpm, and an “Autostart Spinup Time” from 300 to 1500 milliseconds, depending
on how easily the motor can propel the bike up to speed.
On bikes that you pedal to help get you underway, a short 200 to 300 millisecond
ramp will often work best, while a much longer ramp is required if you need to
start moving without pedaling.
If you feel the motor repeatedly trying to start when applying throttle, the
“Autostart Spinup Time” may be too short, the “Autostart Injection Current” may
be insufficient, or the “Autostart Max RPM” may be too low. You may also
generate faults such as “Instantaneous Phase Overcurrent.” To correct this
particular fault, try increasing the “Current Regulator Bandwidth” and/or adjust
the “PLL Bandwidth”. These parameters are found under “Feedback Bandwidth
Tuning” on the “Basic Setup” tab.
7.4 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 Baserunner V6, 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 Baserunner V6 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 in our default
configurations to control regenerative braking.
