Description
The PQP-171-P is a universal pump control module with an integrated power output stage and analogue sensor interface. It is used to control a universal control loop, for example to regulate the swivel angle of a variable-displacement pump. A power output stage for continuous-action valves is integrated, with various adjustment parameters enabling optimum adaptation to the specific valve. The control loop operates with a control cycle time of 1 ms, whilst the integrated power output stage operates with a cycle time of 0.125 ms for magnetic flux control.
Key features and characteristics of the PQP-171-P:
- Universal pump control for proportional directional control valves
- Compact design
- Digitally reproducible setting
- Freely scalable analogue inputs for setpoint and actual value
- Universal PID controller
- Control of proportional valves using one or two solenoids
- Free configuration of ramps, MIN and MAX, dither (frequency, amplitude) and PWM frequency
- Output current can be set up to 2.6 A
- Application-oriented parameterisation
- Can be adapted to all standard proportional valves
- Fault diagnosis and advanced functional testing
- Configuration via USB using the WPC-300 software
Typical applications include swivel angle control. The module can be adapted to all standard proportional valves.
