PSD 43

Integrated direct drive with Nema 23, vertical construction

Special features

  • Space-saving, compact design
  • Maximum flexibility due to alignment as vertical or horizontal design (PSD 42) 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 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 43 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 977 .. 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.

The PSD can be easily addressed by rotary switches (not for IO-Link). The instruments can be mounted on a spindle using the hollow shaft without the need for an additional coupling. The direct drive is also available in horizontal design (PSD 42). The optional rotatable attachment housing allows you to attach the direct drives to the machine in any position, no angle plugs are required.
