Two-Axis Motion Control for SIMATIC S5

The Siemens 6ES5246-4UB21 serves as a positioning module for the SIMATIC S5 programmable controller family. This module controls up to two axes with analog output signals for servo drives . It generates a ±10 V voltage signal for precise speed and torque commands . Consequently, this unit suits traversing, indexing, and continuous positioning tasks.

Signal Interface and Drive Connectivity

The 6ES5246-4UB21 provides two analog outputs for velocity command signals to servo amplifiers . It also supplies one incremental encoder input per channel for position feedback . The module operates on a 24 V DC supply with 150 mA current consumption . Additionally, it supports digital input for reference point and limit switch signals .

Position Data and Memory Configuration

This module stores up to 255 position blocks in its internal memory for sequence programming . Each position block contains target position, feed rate, and acceleration parameters . The Siemens 6ES5246-4UB21 uses nonvolatile RAM to retain configuration data during power cycles . It also provides 16 digital output signals for external status indication or process interlock .

Physical Specifications and Installation

The unit weighs 1.5 kilograms and measures standard S5 single-width module dimensions . It mounts directly into a SIMATIC S5 rack using the built-in backplane connector . The 6ES5246-4UB21 carries an IP20 rating for protection against solid objects . Its front panel includes LED indicators for power, run, and fault status .

Environmental and Operating Conditions

This positioning module functions reliably within a 0 to 60 °C ambient temperature range . It stores between -40 and 70 °C during transport or storage . The device withstands standard industrial vibration and shock levels . Its mean time between failures (MTBF) exceeds 50,000 hours under normal conditions .
