Features:

  • Interface Between the Universal AC Power Source and SIMODRIVE 611 Drive System
  • Combines Capability of AC/DC Power Conversion with Single-Axis Motor Control
  • Operates in Conjunction with the SIMODRIVE 611 Control Unit and Associated Motor Modules
The SIEMENS 6SN1123-1AA00-0EA2 functions as the Power Module within the SIMODRIVE 611 drive lineup, delivering regulated DC power conversion and motor control for single-axis applications. It continuously processes incoming power to drive feed axes at 56 A rated current and main spindles at 60 A rated current, distributing controlled power through the drive bus to support steady state operation of connected servo motors.

The 6SN1123-1AA00-0EA2 provides essential power functions for single-axis drive applications and serves as a critical component of the motion control path, directly affecting the proper, normal operation of the overall drive system. One 6SN1123-1AA00-0EA2 power module is required per controlled axis within the SIMODRIVE 611 configuration. The 6SN1123-1AA00-0EA2 occupies a designated slot position in the drive lineup and integrates with the control unit to execute precise speed and torque commands.

For multi-axis applications, the SIMODRIVE 611 system requires additional 6SN1123 series power modules installed in corresponding axis slots. In addition to standard single-axis operation, the modular configuration also performs coordinated motion control. The SIMODRIVE 611 multi-axis arrangement executes synchronization using the internal bus architecture specified in the drive options.

The 6SN1123-1AA00-0EA2 SIEMENS POWER MODULE may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
