Siemens 6SL3040-1LA01-0AA0 SINAMICS S120 CU310-2 PN Control Unit PROFINET Drive Control Unit

The Siemens 6SL3040-1LA01-0AA0 is a SINAMICS S120 CU310-2 PN control unit with a PROFINET interface, supplied without a CompactFlash card. It offers 11 digital inputs, an analog input/output, and an SSI encoder interface with 30-bit absolute position resolution, running from a 24 V DC supply (20.4-28.8 V) and weighing 0.79 kg.

Technical Specifications

Selection Notes

The 11 digital inputs (versus 5 on the CU305) and 30-bit SSI absolute encoder support put this unit ahead of the CU305 in single-axis and multi-axis line-shaft applications that need more discrete I/O and precise absolute position feedback; machines with lighter I/O demand can use the smaller CU305 instead. It ships without a CompactFlash card, so licensing and firmware need a card ordered separately before commissioning.

Applications

Drive control for SINAMICS S120 single-axis and modular multi-axis systems on PROFINET-based machines that use absolute SSI encoders, such as winders, cross-cutters, and positioning axes.
