Siemens 6SL3055-0AA00-5BA3 SINAMICS S120 Sensor Module SMC20 24V DC

Sensor module for SINAMICS S120 drive systems, converting incremental encoder (Sin/Cos 1 Vpp) and absolute encoder (EnDat) signals to DRIVE‑CLiQ for high‑precision speed and position feedback in multi‑axis servo control.

The Siemens 6SL3055-0AA00-5BA3 is an SMC20 Sensor Module for the SINAMICS S120 drive family. It evaluates signals from incremental encoders with Sin/Cos 1 Vpp interfaces and absolute encoders with EnDat 2.1/2.2 interfaces, providing a DRIVE‑CLiQ output to the higher‑level Control Unit (e.g., CU320‑2). This enables accurate rotor position and speed feedback for demanding motion control tasks such as synchronised axes, printing presses, and high‑speed packaging machines. The compact 30 mm width module is DIN rail mountable and designed for installation in S120 booksize drive cabinets.

Applications

• High‑dynamic positioning in packaging, printing, and converting machinery

• Speed and torque feedback for servo drives on conveyors, gantries, and pick‑and‑place systems

• Retrofitting existing S120 systems with additional encoder channels or replacing older SMC modules

• High‑resolution feedback for motion control in CNC machine tools and robotics

Key Features

• Supports incremental encoders with Sin/Cos 1 Vpp signals (e.g., sin/cos encoders, resolver emulation)

• Supports absolute EnDat 2.1/2.2 encoders with transmission of position values and diagnostic data

• DRIVE‑CLiQ interface for automatic component configuration with the Control Unit

• Signal evaluation up to 500 kHz (encoder dependent)

• Shielded encoder cable length up to 100 m

• Diagnostic LEDs for status and error indication

• 30 mm width for space‑saving cabinet mounting

• IP20 protection (rated for cabinet installation)
