PSW 31_-8 Positioning System

Positioning system with protection class IP 68 for wet area applications

Special features

    • 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 (not for 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
