2 Characteristics
This electronic module has been developed for controlling hydraulic positioning drives. Proportional valves
with integrated or external electronics can be controlled with the differential output.
The internal profile generation is optimized for stroke-dependent deceleration or the NC control mode. The
controller and the controller settings are adapted to typical requirements and thus permit rapid and uncritical
optimization of the control behavior. The optimized control function offers a high degree of precision together
with high stability for hydraulic drives. The movement cycle is controlled via the external position and speed
inputs.
The high resolution of the analogue signals ensures good positioning behavior.
Alternatively, the P version is available with an integrated power output stage (see additional information:
POWER OUTPUT STAGE). The advantage of the integrated power output stage is founded in the integrated
control behavior without additional dead times. This allows higher dynamics and higher stability respectively.
The SSI extension is available for use with digital sensors (see additional information: SSI INTERFACE).
Sensors with a resolution of one µm can be used for very high position accuracy.
Setting up this module is simple and easy to handle with our WPC-300 start-up software.
Typical applications: general positioning drives, fast transport drives, handling systems, speed-controlled axes
and also tracer control.
