f. In the Speed Mode » Response menu, adjust the remaining three brake rate
parameters as necessary while reversing the throttle input (i.e., full throttle
forward to low throttle reverse, full throttle forward to full throttle reverse,
full throttle reverse to low throttle forward, etc.).
If a brake input is present in the application (Brake Pedal Enable = On)
continue adjusting these three brake rates by applying dierent amounts of
brake throttle (i.e., full throttle forward, then apply full brake or full throt-
tle forward, then apply low brake, etc.). For AC pump applications these
parameters have no eect on performance since the AC pump will not run
in reverse nor with a brake input.
g. e parameters in the Speed Mode » Response » Fine Tuning menu typically
do not need to be changed as the default values work well in most applica-
tions.
AC pump motor applications, which in step “a” had the Pump Enable parameter
set to On, may also be controlling hydraulic valves (load hold valve, proportional
valve). e Proportional Driver parameters (page 52) and some VCL will typ-
ically be used to set up the control of these valve driver outputs. Consult with
your Curtis distributor or support engineer regarding hydraulic valve control.

a. Set Max Speed to the maximum speed you want to limit the motor to.
b. Kp, Ki, and Kd typically do not need to be changed as the default values
will work well in most applications. ese parameters control how tightly
the controller limits the speed of the motor to the programmed Max Speed.
c. Set Typical Max Speed (page 55) to the expected maximum speed of the motor.
d. Adjust the parameters shown in Figure 9 (page 40) to set up the throttle
mapping:

e. In the Torque Mode » Response menu, adjust the four accel, decel, and release
rate parameters as necessary while moving the throttle to dierent positions
(i.e., neutral to full throttle, half throttle to full throttle, full throttle to half
throttle, full throttle to neutral, neutral to low throttle, etc.).
f. e other parameters in the Torque Mode » Response » Fine Tuning menu
typically may need to be changed for some applications. Read the parameter
descriptions and adjust as necessary.
