Product description
Applications
2-axis control in presses, forming machines and machine tools.
Plug-in connections
2 x DIN 41612, 32-pole, for low-power signals (command value, enable, etc.).
Screw-plug-in connection to the valve and for supply voltage on handle side (ST 4, 5 and ST 9, 10) included in the scope of delivery.
Test points
IC base on handle side for control measurements and signal inputs.
Displays
For cable break, enable and undervoltage.
Direct voltage controller (DC/DC converter)
For the supply of command value encoders, position transducers and internal supply together for both channels.

Project planning information
The amplifier card may only be unplugged and plugged when de-energized.
The distance to aerial lines, radios, and radar systems has to be at least 1 m.
Do not lay solenoid and signal lines near power cables.
For signal lines and solenoid conductors, we recommend using shielded cables.
The cable shield must be connected to the control cabinet extensively and as short as possible.
The valve solenoid must not be connected to free-wheeling diodes or other protection circuits.
The cable lengths and cross-sections specified in the technical data must be complied with.
Mounting
Wiring information
Power zero and control zero c14/c12 must be bridged.
If the distance to the power supply unit is <1 m, directly onto the DIN connector at c2/c4.
With larger distances, lead the control separately to the ground.
Connect the supply voltage to connectors ST 4 and ST 9.
