MeloAuto-Trusted PLC & DCS Parts Supplier
This positioning module controls single-axis motion tasks with high precision. It integrates directly into the SIMATIC S5 programmable logic controller system. Therefore, this component suits packaging, pick-and-place, and CNC applications.
Physical Dimensions and Mounting Details
The Siemens 6FM1723-3CA00 occupies a single wide slot in the S5 rack. Its compact housing measures 233 mm in depth from the front panel. The module weighs approximately 0.8 kg for standard handling. Consequently, technicians can install this unit without extra rack reinforcement.
| Parameter | Specification |
|---|---|
| Product Model | Siemens 6FM1723-3CA00 |
| Slot Width | 1 x standard S5 slot |
| Depth | 233 mm |
| Weight | 0.8 kg |
Interface Configuration and Connectors
The Siemens 6FM1723-3CA00 provides a 15-pin D-sub connector on its front plate. This interface handles incremental encoder signals and digital I/O lines. A separate 5-pin terminal block supplies the drive interface connections. Hence, users can wire this module directly to servo or stepper drivers.
Component Count and Onboard Features
This module contains one main printed circuit board with multilayer construction. The board holds a dedicated 16-bit microprocessor for motion calculations. Additionally, you will find two optocoupler arrays for signal isolation. These components protect the backplane bus from external electrical noise.
| Technical Feature | Description |
|---|---|
| Encoder Interface | Incremental (5V differential) |
| Digital Inputs | 4 x 24V DC, opto-isolated |
| Digital Outputs | 4 x 24V DC, 0.5A each |
| Processor Type | 16-bit dedicated motion controller |
Energy Storage and Power Consumption
The Siemens 6FM1723-3CA00 draws 250 mA from the 5V backplane supply. A small electrolytic capacitor bank maintains position data during brief power dips. This energy storage lasts approximately 20 milliseconds under full load. Therefore, the module retains axis status without external batteries.
Positioning Accuracy and Feedback Handling
The module reads encoder signals at a maximum frequency of 100 kHz. It calculates position values with a resolution of 1 micrometer per encoder count. Users can define up to 255 programmable target positions. This flexibility allows smooth motion profiles for complex production sequences.
