April 2007Counters, Panel Meters, Tachometers and TimersSpecial Function ControlsPosition Control75Product DescriptionThe 58868400 closed-loop positioncontrol provides digital output signals(run, direction and fast/slow) to a driveto cause a motor-driven tool to bepositioned along a single axis. Thesesignals can also be used to control valuesin a hydraulic positioning system.Typically, a quadrature encoder, coupledto the drive mechanism, providesthe feedback signal to the positioncontrol. Up to five destinations can beautomatically sequenced through in amove-and-dwell process, or the operatorcan select a single destination formove-and-stop positioning.Features■ 6-digit, LED display, 14 mm (0.56")high characters■ 4 move registers plus home■ 2 Form C relays and 5 NPNtransistor outputs■ 28 kHz count speed■ 5 dwell time settings■ 15V DC @ 100 mA power output■ Manual or automatic operation■ Programmable offset, prewarn andkerf values■ Backlash compensation■ Programmable high/low limits■ 20 mA current loop communications■ NEMA 4X front panelStandards and Certifications■ UL ListedCat.
