Servo Control Module
The 1746-HSRV servo control module is a single-axis, closed-loop servo controller
which can be operated with a variety of SLC 500 processors and features block execution
independent of the scan time of the processor. For fast and accurate control, the module
monitors encoder feedback up to 300 kHz.
Ladder logic controls all of the motion. Complicated moves are accomplished using
blended motion profiles stored in the module’s internal memory and can be executed
repeatedly. The profiles are stored as a series of absolute moves, and additional moves or
homing operations can be performed between blended moves. The module can reset the
absolute position when an encoder marker pulse is detected.
Positioning Modules
Open-Loop Velocity
This module provides an ideal control strategy for simple hydraulic applications. It can
accelerate and decelerate the hydraulic ram, using as many as seven extend and seven
retract segments.
Compatible LDTs are:
• Balluff BTL-2-L2 or -M2
• Gemco Quick-Stick II
• Santest GYRP or GYRG
• Temposonics II with DPM or RPM
