6.5 Motor Thermal Rollback via Baserunner
To use the controller's built
in motor temperature
rollback, it is necessary to
create a voltage /
temperature map of this
signal by putting appropriate
values in address 93-98
from the “edit parameters”
menu, and also ensure that
the “Motor Temperature
Source” is set to [2]BMS.
Full support of the motor
thermal rollback settings will
be provided in later software
releases.
6.6 Regenerative Braking
The Ebrake signal on the 9 pin Main cable is an analog input that provides
proportional braking control if desired. This is pulled to 5V internally, while the
throttle signal is pulled low. If the throttle and ebrake signal are shorted together,
then the signal level will sit at 1.0V, allowing a single wire bidirectional torque
control with 0-0.9V mapped to regenerative braking, and 1.1-4.0V mapped to
forwards torque.
If these signals are not shorted together then a simple ebrake switch to ground
will activate maximum regen. Alternatively a secondary throttle can be wired to
this input to achieve proportional braking without a Cycle Analyst, in which case
the regenerative brake mapping should be reconfigured to have similar start and
end voltages as the throttle signal.
