    AI Overview
    Siemens SINAMICS S120/G130/G150 drives support parallel connection of up to 4 or 8 power units for high-power applications, often requiring specific Control Unit (CU320-2) CIM versions for optimal performance. Parallel configurations must use identical power units, requiring precise wiring for synchronization and configuration via SINAMICS Engineering Manuals to manage power sharing and load balance. 
    Siemens Inverter Parallel Connection Guidelines 
    • Capacity: SINAMICS S120 systems allow parallel operation of up to 4 Motor Modules to increase capacity, or up to 8 for specific power units.
    • Requirement: All parallel-connected power units must have the same voltage, power rating, and current rating to ensure proper load sharing.
    • Hardware and Firmware: Use the same CIM/IPD configurations for all parallel units. Obsolete components like older CIB&PSB boards may require upgrading to modern alternatives.
    • Commissioning: Parallel modules must be commissioned, often via Siemens Support, to configure the proper operation of the modules. 
    CIM Version and Configuration (SINAMICS G130/S120) 
    • CIM Module: The Control Interface Module (CIM) manages the interface between the control unit and the power section. For older G130 units, the obsolete CIB+PSB configuration is often replaced by newer CIM configurations in modern replacements.
    • CU320-2: The SINAMICS S120 uses the CU320-2 Control Unit (PN or DP), which supports multi-axis and parallel configurations. 
    Key Considerations for Parallel Operation 
    • Balancing: Proper cabling (length and impedance) is crucial to avoid uneven current distribution.
    • Line Components: For paralleling line modules, matching line reactors are necessary for proper operation.
    • Replacement: When replacing a power module in a parallel system, it is recommended to follow Siemens Support procedures to ensure the new module is configured correctly. 
    For detailed configuration information, the Siemens Industry Mall provides tools for selecting and configuring systems with parallel components.

    What is the difference between Siemens G120 and G120X?
    The G120X is purpose-built for water, air, and infrastructure systems, offering robust, application-specific features at a lower cost. However, if your system demands high-performance motion control, advanced safety, or energy regeneration, the more versatile G120 is the way to go.Jul 31, 2025
