PSS 31_-8 Positioning System

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 (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
