These parameters dene the percentage of regen current limit or
braking current limit that will be applied at the speeds dened by the
nominal speed and delta speed parameters.
The curve can be shaped to limit the available torque at various
speeds. One possible use is to compensate for the torque-speed
characteristic of the motor.
Figure 16 illustrates two typical usages of these parameters.

Figure 17
Eect of throttle adjustment
parameters. Together these
four generic parameters
determine the controller’s
response to throttle demand
(in forward or reverse) and
to brake demand.
In the examples shown in
this gure,
Deadband = 0.5 V
Max = 4.5 V
Oset = 0.
