GE IC693DSM314-BE Digital Servo Module

Overview

The GE IC693DSM314-BE is a high-performance digital servo module for Series 90-30 PLCs. It provides precise, closed-loop motion control for up to two independent axes. The module integrates directly with PLC logic for real-time motion coordination. It supports GE Fanuc digital servos and compatible third-party drives. The module handles point-to-point, velocity, and electronic gearing motion types. Two strobe inputs per axis capture positions with ±2 counts accuracy. Onboard diagnostics monitor drive faults, following errors, and limit switch status. Firmware updates are possible via the front-panel COMM port.
