Detailed Feature Overview

This controller uses a PID algorithm for smooth and accurate positioning. You can adjust proportional, integral, and derivative gains independently. The analog input reads ±10 V signals with 14-bit resolution.

A 470 µF capacitor filters the analog output for stable drive signals. Consequently, your servo valve receives noise-free command voltages. The control deviation deadband prevents unnecessary correction movements near the target.

You will find four digital inputs for enable and limit switches. These inputs stop axis motion immediately when triggered. Three digital outputs indicate position reached, error status, and module readiness.

Installation and Compatibility

Siemens 6ES5241-3CA13 fits any S5 rack slot except the CPU position. Connect position feedback sensors using shielded twisted-pair cables. Set the PID parameters via STEP 5 software or manual potentiometers.
