Integrated direct drive with Nema 23 in horizontal construction

Special features

  • Space-saving, compact design
  • Maximum flexibility due to alignment as horizontal or vertical design (PSD 43) and the optional rotatable actuator housing
  • Galvanically separated supply voltages for control and power electronics
  • Optional gearbox for more torque
  • Precise position feedback thanks to an absolute measurement system without battery
  • Easy and low-cost mounting via optional 8 or 14 mm hollow shaft
  • Address may be set using the bus or an address switch (not for IO-Link)
  • Status LEDs visible from the outside

PSD 42 direct drive is a mechatronic drive 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 direct drive 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 vertical design (PSD 43). The optional rotatable attachment housing allows you to attach the direct drives to the machine in any position, no angle plugs are required.

Options

  • Optional with 8 or 14 mm hollow shaft with torque support
  • Optional with gearbox for up to 8 Nm torque
  • Optional with IP 65 (installed, motor shaft IP 50)
  • Software modules for IO-Link: changeover of parameter set, target speed in process data and modulo function
  • Available in company colour on request
