Siemens 6ES5247-4UA11 Positioning Module

The Siemens 6ES5247-4UA11 positioning module provides closed-loop axis control for SIMATIC S5 systems. This module manages stepper motors and servo drives for precision movement applications. It mounts directly into any S5-115U or S5-135U rack slot. You can use this module as a direct replacement for failed positioning units.

Detailed Technical Specifications

The Siemens 6ES5247-4UA11 positioning module measures 250 mm in length. Its width reaches 160 mm across the main body. The total height goes up to 42 mm with all components installed. This unit weighs approximately 0.55 kilograms for secure mounting.

Key hardware parameters include:

Complete Model: Siemens 6ES5247-4UA11
Component count: 98 individual electronic parts
Connector ports: One 20-pin screw terminal block
Energy storage: Four aluminum capacitors (100 µF each)
Mounting system: Two rear locking levers
PCB layers: Six-layer industrial construction
Control axes: 1 axis with step/direction output
Output frequency: 0 to 25 kHz programmable
Position range: 16-bit counter (±32,768 steps)
Input channels: 3 digital limit switch inputs

Application and Installation

The Siemens 6ES5247-4UA11 positioning module slots into any S5 rack alongside the CPU. It requires an external stepper drive for motor power amplification. This module reads incremental encoders for position verification. Consequently, you can implement precise single-axis positioning for conveyors and indexing tables.

Programming and Reliability

This module accepts position data from the S5 CPU via backplane communication. The Siemens 6ES5247-4UA11 stores motion profiles in onboard RAM with battery backup. You program the module using standard S5 function blocks (FB 170 to FB 179). Therefore, integration with existing S5 programs requires minimal additional coding.

Always power down the rack before inserting or removing this module. Wire the limit switches using shielded cables for noise immunity. The module features LED indicators for power, run, and limit status. Furthermore, its conformal coating protects against dust and light moisture.
