Application Software

Electronic valve control system

for hydraulic valves, version 10

RE 95 350/03.06 1/12

Features

Hydraulic operating functions are controlled via valves whose

positions are speciﬁ ed by target value generators, such as e.g.

joysticks.

• The electronic valve control system is an easily adjusted

software package for controlling hydraulic valves. It is used to

match the valve behavior to the respective application.

• The valve control system is available in three variants:

- Variant A for 1 axis (VACA)

- Variant B for 2+1 axes (VACB)

- Variant C for 3+1 axes (VACC)

The valve control system is designed for Rexroth hydraulic

valves.

• The valve control system can be easily adapted by the user

to various joystick, valve and control block conﬁ gurations by

means of adjustment parameters.

• The valve control system is suitable for Rexroth CAN joysticks

and CAN valves.

• Diagnostics and parameterization can be carried out using the

BODEM PC software or the BB-3 control panel.

RE 95 350/03.06 Bosch Rexroth AG VAC Valve Control System Method of function The VAC electronic valve control system allows the pressure in pressure reduction valves to be controlled via signals from a joystick in accordance with a parameterizable characteristic curve. In this way, the volume ﬂow in hydraulic cylinders or hydraulic motors is controlled via directional valves. The valves form part of a control block with which the movement speed of machine parts can be controlled.

/12 Bosch Rexroth AG Important features • Various joystick types are available for target value speciﬁcation. • The ramp times can be set for each movement direction and axis. • There are various characteristic types (linear to progressive) which can be set for each movement direction and axis. VAC Valve Control System RE 95 350/03.06 Parameterization and diagnostics The parameters that need to be assigned for commissioning the VAC valve control system can be set easily using the BODEM PC software.
