MOOG Servo Electronics Products

​Product Overview

Moog servo electronic equipment is a modular product system designed for the needs of electro-hydraulic servo control. Its core advantages lie in modular combination, multi voltage compatibility, and wide temperature adaptability. It can be customized to build open-loop/closed-loop control systems through Eurocard, Snap Trac, DIN Rail modules and supporting sensors and testers, covering the full scenario requirements from single axis simple control to multi axis complex collaboration. It is widely used in industrial automation, hydraulic systems, valve control and other fields.

Core control mode and configuration scheme

(1) Five major control modes

table

Key configuration steps for applicable scenarios of control mode core components

Open loop position control servo amplifier, actuator, command potentiometer simple positioning, manual monitoring feedback zero bias → set gain → hydraulic testing

Closed loop position control (2-stage valve) servo amplifier, position sensor, actuator precise positioning, no need for manual intervention zeroing → gain setting → stability testing

Closed loop position control (3-level valve) servo amplifier+oscillation demodulator, LVDT sensor precise positioning for high flow requirements, independent adjustment of inner/outer loop gain → zero bias calibration

Force control servo amplifier, signal conditioner, pressure sensor/load cell constant force output scene pressure signal calibration → force voltage conversion → gain adjustment

Speed control (with acceleration limit) servo amplifier, tachometer, I-V converter constant speed control (such as conveyor, mixer) integral control setting → speed range calibration → stability testing

(2) Typical Configuration Example

Dual axis PLC servo system (Snap Trac): N123-139 (I-V conversion)+N123-137 (ramp generation)+N121-132A (servo controller)+position sensor+DC level detector, realizing PLC instructions to dual axis cooperative control;

Complex multi axis system (Eurocard): E128-210 (power supply)+G122-202A1 (servo amplifier x multiple blocks)+NF123-204A1 (oscillation demodulator)+NE123-212-1 (DC level detection), supporting cooperation of more than 3 axes.

Key Performance and Installation Requirements

Environment and Protection: Operating Temperature -20 ° C to 50 ° C; Outdoor Installation Requires NEMA 4 Sealed Cabinet; The Eurocard/Snap Trac needs to be installed in an electrical cabinet with sufficient cooling;

Electrical specifications: AC power supply module compatible with 50-60Hz; DIN Rail module requires stable 24VDC power supply; The signal cable needs to be shielded, and the grounding terminal is only grounded on the amplifier side;

Safety reminder: Before starting the closed-loop system, it is necessary to cut off power and release pressure; First power on, gradually adjust the gain to avoid oscillation/overload; Hydraulic pipelines must comply with pressure specifications to prevent component damage.
