Description
The Siemens 6SN1123-1AA00-0BA1 (and its variants 0DA2, 0HA1, 0HA2, 0AA1, 0AA2, 0BA2, 0CA1) is a SIMODRIVE 611 Single-Axis Power Module, a high-performance servo drive power stage designed for precise speed and position control in industrial automation applications. This power module is part of the modular SIMODRIVE 611 drive system, delivering regulated DC bus power to connected servo motors (1FT5, 1FT6, 1PH series). It features internal cooling, comprehensive protection against overvoltage, overcurrent, and overtemperature, and supports seamless integration with SIMODRIVE 611 control modules for closed-loop motion control. With a rugged metal housing and IP20 protection rating, it is suitable for harsh industrial environments. Various current ratings are available across the suffix variants, ranging from 8A (0HA1) to 135A (0DA2), making this series adaptable to a wide range of motor power requirements.
