Circuitry Of Hs5E - Bosch REXROTH A4 Series Instruction Manual

5.7.1 Circuitry of HS5E

The two illustrations below show the circuitry for master/slave operation with analog
signals. As an alternative to this, you can also set up master/slave operation by
means of a fieldbus system and the machine control. For more information on this
system, refer to the functional description of the firmware.

notes:
– For the configuration of analog command value specification, see the
HydraulicDrive functional description (see data sheet 30338).
– The port for the pump's position transducer is not drawn in.
– As an option, you can install the coupling element (relay, analog switch) to
regulate both pumps independently from one another. With the slave pump, this
means that it is possible in the suggestion shown here to carry out both swivel
angle and pressure control.
