Halstrup Walcher Smart Positioning drive PSD 41


Space-saving, compact design

  • Maximum flexibility due to alignment as horizontal or vertical design (PSD 40) and the optional rotatable actuator housing
  • Galvanically separated supply voltages for control and performance electronics
  • Precise position feedback thanks to an absolute measurement system without battery
  • Easy and low-cost mounting via optional hollow shaft
  • Optional gearbox for more torque
    • Address may be set using the bus or an address switch (not for IO-Link)
  • Status LEDs visible from the outside

PSD 41 direct drive is a mechatronic system with integrated control, bus interface and absolute measurement system without battery. This drive is ideal for automatic format changeover. The stepper motor with integrated control and bus communication permits higher velocities at lower torques.

The absolute measuring system at 986 ..4026 rotations eliminates the need for time-consuming reference runs and increases the efficiency of the machine. Direct measurement of the position 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.
