Low-cost positioning module for single axis, providing excellent characteristics with all kind of closed loop position control. Optimized polynomial speed profiles for smooth and precise approach to the target position Operation modes for inching, absolute position and repeating cycles of fixed positions Incremental position feedback according to RS 422 encoder standard Max. feedback frequency 80 kHz at a control cycle time of only 100 ?sec., therefore suited also for very dynamic applications Remote index input provides positioning related to print marks etc. Easy setup and commissioning procedure by PC operator software Full remote control and register access via serial link when using a PC or one of the mks operator terminals. Linking to PROFIBUS possible by use of the PB251 gateway.(see accessories) Power supply 18 30 V, built-in aux. voltage output 5 VDC for encoder supply Analogue output +/- 10 V for speed reference of the positioning drive Closed 19 steel cassette for rack mounting and for mounting to DIN rails
