Integrated Automotive Control
for MP1 and H1P single pumps
The Automotive Control (AC) is an electric NFPE
control with an integrated micro-controller, installed
on the pump. The integrated micro-controller
enhances control performance with a flexible,
configurable control scheme for an entire single path
propel transmission. It can be used in combination
with fixed and variable displacement hydraulic
motors. The propel system can be used with
mechanical controlled or CAN controlled engines.
With the pre-installed application software and easily
changeable control parameters, it is possible to tailor
the vehicle‘s driving behavior to the individual
requirements of the customer. Target applications
with a load dependent driving behavior:
•
Wheel loader, telehandler, dumper (torque
controlled)
•
Sweeper, snow blower, forestry machines (speed
controlled)
Features
Basic functions
•
Four system modes, selectable by the
driver for different drive behaviour
•
