PLCs, Power Supplies & Others

This positioning module delivers precise axis control for demanding motion applications. It integrates seamlessly into the Siemens SIMATIC S5 programmable controller platform. The unit controls single-axis positioning tasks with exceptional speed and accuracy. Users can implement point-to-point positioning, referencing, and velocity control efficiently.

Axis Control and Positioning Capabilities

This module supports single-axis positioning with incremental or absolute encoders. It generates pulse train outputs for stepper and servo drive systems. The unit includes integrated homing and referencing functions for repeatable positioning. Users can configure acceleration, deceleration, and target positions through software. This capability suits pick-and-place machines, conveyor indexing, and cutting applications.

Pulse Train Generation and Motion Profiles

The 6FM1726-3BA00 generates pulse train outputs with frequencies up to 200 kHz. This high frequency enables precise velocity control for high-speed axes. Users configure acceleration ramps to minimize mechanical shock and vibration. The module supports multiple motion profiles including trapezoidal and S-curve types. Trapezoidal profiles suit most standard positioning tasks. S-curve profiles reduce mechanical wear in demanding applications.

Encoder Interface and Position Feedback

This module accepts incremental encoder signals with TTL or RS-422 levels. It also supports SSI absolute encoders for position retention without referencing. The unit counts encoder pulses for real-time position monitoring. Users can set software limits to prevent axis overtravel. The module also supports hardware limit switches for additional safety. This combination of feedback options ensures reliable position detection.

Homing and Reference Point Management

The module supports various homing methods for flexible axis referencing. Users can perform homing using reference cams or hardware limit switches. The unit also supports software-defined home positions for simplified setup. After homing, the axis maintains absolute position awareness through encoder feedback. This feature ensures consistent positioning across power cycles. Consequently, operators achieve repeatable production quality without manual recalibration.

Configuration and Diagnostic Functions

Users configure all positioning parameters through the Siemens programming software. The module stores configuration data in non-volatile memory for automatic loading. Diagnostic functions monitor position deviation and following error conditions. The unit reports any positioning faults to the PLC for immediate response. Front-panel LEDs indicate operational status and fault conditions. These indicators simplify troubleshooting without additional tools.

Power Consumption and Environmental Specifications

The module draws 400 mA at 5 V DC from the S5 backplane power supply. Power dissipation remains below 3 W under normal operating conditions. The unit operates reliably between 0 °C and 60 °C ambient temperature. Humidity tolerance spans 5% to 95% without condensation issues. The module carries an IP20 rating for protection against solid objects. This robust design suits packaging, material handling, and simple assembly applications.
