REVERSE SPEED
(set at 40%)
CREEP SPEED [default access: OEM]
Creep speed helps to prevent vehicle rollback on inclines when the brake is
released but low throttle is applied. It is activated when the throttle is rotated out
of the throttle deadband (typically 8% of the full throttle range). The throttle
response is rescaled so that the controller’s output is adjustable over the full
throttle range, but starting at the programmed creep speed value. Creep speed is
programmable from 0% to 25% of the PWM duty cycle.
EMR REV SPEED [default access: OEM] (123X models only)
The emergency reverse speed parameter sets the speed at which the vehicle
moves away from the operator when the belly button input (Pin 10) is active. The
vehicle will move at this speed any time the belly button input is active, regardless
of throttle position. The emergency reverse speed is adjustable from 0% to 100%
of the PWM duty cycle. NOTE: If the controller is not factory-configured for the
emergency reverse option, this parameter will not be displayed in the Program
Menu.
