This module specializes in open-loop velocity control, providing a reliable method for managing the speed and positioning of hydraulic or pneumatic actuators. By integrating feedback from a Linear Displacement Transducer (LDT) and processing motion instructions directly from the SLC processor, the 1746-QV enables smooth, profiled motion in systems that do not necessitate complex closed-loop servo synchronization.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSingle-axis motion control capability for SLC 500 systems.\u003c\/li\u003e\n\u003cli\u003eSupports integration with Linear Displacement Transducers (LDT) for precise position feedback.\u003c\/li\u003e\n\u003cli\u003eProgrammable motion profiles allowing for up to seven distinct voltage levels to manage acceleration and deceleration.\u003c\/li\u003e\n\u003cli\u003eAnalog output range of -10V to +10V DC for versatile actuator drive control.\u003c\/li\u003e\n\u003cli\u003eOptimized for reducing mechanical stress and pressure spikes in hydraulic applications.\u003c\/li\u003e\n\u003cli\u003eFast update time of 2 ms for responsive motion execution.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThe 1746-QV is particularly well-suited for industrial machinery requiring controlled, non-CNC motion, including hydraulic presses, industrial welders, and die casting equipment.
