3 — PROGRAMMABLE PARAMETERS: Speed and Throttle Parameters
e 1253 controller can accept inputs from up to four individual speed select
switches (SS1–SS4) and from an analog throttle. e controller adjusts the pump
motor’s PWM output in response to these inputs, using the algorithm prescribed by
the programmed acceleration rate to reach the appropriate maximum speed.
e programmed Minimum Speed and Acceleration Rate are in eect regardless
of whether the speed request comes from a speed select switch or a throttle.
SS1–SS4 SPEED
e SS Maximum Speed parameter defines the maximum allowed armature
PWM output of the pump motor. It can be set independently for up to four
individual speed select switches (i.e.,
SS1 SPEED, SS2 SPEED, etc.). e maximum
speed parameter is adjustable from 0% to 100% of the full output.
THRTL MAX SPEED
e rottle Maximum Speed parameter defines the maximum allowed armature
PWM output in response to throttle input. e maximum speed parameter is
adjustable from 0% to 100% of the controller’s full output.
MINIMUM SPEED
e Minimum Speed parameter defines the minimum allowed armature PWM
output of the pump motor, and is adjustable from 0 to 50% of the full output.
e minimum speed feature ensures that adequate pressure is maintained for
the power steering system and for pump lubrication.
ACCEL RATE
e Acceleration Rate parameter defines the time it takes for the controller
to accelerate from 0% output to 100% output when a speed select switch is
closed or a full throttle request is made. e acceleration rate is adjustable from
0.2 to 3.0 seconds.
Most applications use a throttle to provide variable speed control of a specic hy-
draulic operation (e.g., lift, reach, tilt, shift, rotate). A throttle gives the operator
more exibility and control over performance than is provided by switch inputs.
THROTTLE TYPE
e 1253 controller accepts a variety of throttle inputs, including 5kΩ–0 and
0–5kΩ two-wire rheostats, 3-wire pots, and 0–5V throttles. e standard throttle
input signal type options—Types “0” through “3” in the Program Menu—are
