2 Device description
2.1 Features
The PSE2xxMod positioning system, an intelligent, compact, complete solution for
positioning auxiliary and positioning axes, consists of an DC motor, gear power
amplifier, control electronics, absolute or partially absolute measuring system and
Modbus interface.
Variants with partially absolute measuring system (“singleturn encoder”) indicate the
position of the output shaft after power up without executing a movement. Additionally
the number of turns is being loaded out of the flash memory, thus after power up the
correct position of the output shaft will be indicated (assumed the shaft has been
turned for less than half a turn while powered down).
Variants with absolute measuring system (“multiturn encoder”) also indicate the
position of the output shaft after power up without executing a movement. To detect
the number of turns, instead of a flash memory a measurement gearbox is used. So
always the true position is indicated, even if the shaft has been moved while powered
down. This eliminates the need for a time-consuming reference run.
Connecting to a bus system simplifies the wiring. A hollow shaft with adjustable collar
or a solid shaft makes assembly quite simple. The positioning system is especially
suitable for automatically setting tools, stops or spindles for wood-processing
equipment, packing lines, printing equipment, filling units and other types of special
machines.
PSE2xxMod positioning systems convert a digital positioning signal into an angle of
rotation.
