Positioning system

PSE 30_-8


Positioning system with 

protection class IP 54


Positioning system with 25 W power output

Special features

  • Space-saving, compact design
  • Galvanically separated supply voltages for control and performance electronics
  • Durable EC-motor
  • Extremely accurate positioning due to measurement of the position at the output side
  • Easy and low-cost mounting via hollow shaft
  • Bus interfaces simplify start-up and wiring complexity
  • Address may be set using the bus or an address switch (not for IO-Link)
  • Baud rate set via switch
  • Status messages retrievable via bus

The PSE 30_-8 positioning systems are intelligent, compact solutions for the automatic adjustment of auxiliary and positioning axes comprising an EC-motor, gear, controller, measuring system and CANopen, PROFIBUS DP or Ethernet-bus interface. The integrated electronic control feature frees up the machine´s central control unit. No external motors, proximity or limit switches are required.
The absolute measuring system at 250 rotations eliminates the need for time-consuming reference runs and increases the efficiency of the machine. Direct measurement of the position at the output shaft ensures highly accurate positioning. The galvanically separated supply voltages for the control and performance electronics permit the implementation of an emergency shut-off function without interrupting communication with the control module.
Address and baud rate switches simplify start-up, even without the knowledge of the control software. The instruments can be mounted on a spindle using the hollow shaft without the need for an additional coupling. Two bus connections are available for looping the bus signal (not for IO-Link). Set-up mode or manual positioning permits the connection of jog keys (optional, not for IO-Link).
