  • Software: Start-up software WPC-300 for fast and simple adjustments of our digital control modules and ZYLINDER.XLS for simple calculation of the control parameter of cylinder drives.
     
  • Command signal modules: Different modules adjustable via the serial interface (notebook or hand held terminal) or via potentiometer. Universal PID controller and speed control modules with integrated power stage are also in this section.
     
  • Positioning controllers: Different controllers beginning with simple stroke depended deceleration and going up to axes controller in NC-mode and with or without Profibus DP interface.
     
  • Control modules and specialized pressure control modules: PID-, pressure and speed control modules for general use and pq-control modules for flow control and closed loop pressure limitation control.
     
  • Synchronization control modules: Begins with synchronization control in bypass to a flow divider and goes up to 18 axes synchronization and positioning control with Profibus DP and CAN-Bus. We offer a complete range of solutions for all different applications.
     
  • Pump control modules: These modules are specialized to control servo pumps in typical applications. The possibilities are: closed loop displacement control (all pump types), open loop displacement control with closed loop pressure and power control (for example: HAWE inline), closed loop displacement, pressure and power control (for all pump types) and also solutions for closed hydraulic circuits.
     
  • Power amplifier: for proportional valves. Key advantages: general use with all proportional types and easy adjustment, analogue and digital versions and an attractive price by simplest handling.
