Mobile Hydraulics Bosch Rexroth AG
Dual Path Control DPC
RE 95 325/03.04
13/16
Important Features
• The travel speed setpoint is defined via a lever.
• The steering setpoint is defined separately via a steering
potentiometer.
• By deflecting the steering potentiometer with the lever in the
neutral position, it is possible to steer on the spot.
• To define the travel behavior, either transport mode or work
mode can be selected.
• Speed regulation for controlled straight line driving is built in.
• Variant B only: The vehicle can be steered automatically via
a steering sensor.
• A brake control is integrated.
• For the travel speed, an analog actual value (0-5 V) can be
detected.
• Automatic calibration of both drives allows compensation of
hydraulic differences.
• Variant C only: Additional tamper and vibration functions can
be actuated via proportional outputs
• Travel behavior is monitored by different safety functions.
• The steering and speed potentiometers are monitored for
cable breaks and short circuit.
• The inputs and outputs of the control unit are monitored
(cable breaks, short circuit). In the event of a fault or if the
emergency stop switch is operated, the drive is stopped im
-
mediately.
• Faults can very easily be indicated by the connected error
lamp.
• Variant C only: All errors can be output via the CAN bus
interface to the DI2/11 display.
• Any faults that occur are logged in the control unit and can
be read later on with BODEM or BB-3 in plain text.
Main Parameters
• Potentiometer for steering (dead band, steering behavior)
• Lever for travel direction (dead band, acceleration behavior,
braking parameters)
• Configuration (speed regulation, speed display, speed
pulses in hydraulic motor, automatic calibration of minimum
currents for controlling the pumps)
• Minimum and maximum magnet current for pumps forwards
and backwards
• Variant B only: Configuration of automatic steering
• Variant C only: Potentiometer for additional functions (time
ramps)
• Variant C only: Minimum and maximum magnet current for
the additional functions
Parameter Setting and Diagnostics
The parameters which have to be set for commissioning the
DPCB/C dual path control system can easily be adjusted with
the BODEM PC software
For diagnosis and troubleshooting, you can display the main
process variables and error messages with BODEM.
Instead of BODEM, you can also use the BB-3 control panel
for defining parameters and diagnostics.
