Positioning system

PSS 31_-8

Positioning system with protection class IP 65


Positioning system with protection class IP 65 for damp area applications

  • Positioning system with absolute measuring system, without battery
  • Hygienic design
  • Galvanic separation of motor and control unit prevents the control unit from being affected by any EM interference in the motor 
  • Easy mounting with hollow shaft possible (also available with solid circular shaft)
  • Absolute encoder eliminates the need for reference runs during system setup and installation of replacements
  • Easy address assignment directly on the device using integrated address switches (nicht für IO-Link)
  • Regulation of the current torque prevents overloading and unnecessary run aborts
  • Strong breakaway torque enables safe start-up even after an extended standstill
  • Intelligent running behaviour. Recognises the difference between obstacles and dirt
  • Spindle offset run: Excludes inconsistencies due to lash in the spindle.
  • Condition monitoring of supply voltage, drag error (permits optimum adjustment of current position), power consumption and torque
