Siemens 6SL3040-1LA01-0AA0 SINAMICS S120 Control Unit CU310-2 PN PROFINET 24V DC

Motion control unit for SINAMICS S120 drive systems, managing a single motor axis via PROFINET IRT for high‑speed, coordinated machine control.

The Siemens 6SL3040-1LA01-0AA0 is a CU310-2 PN control unit for the SINAMICS S120 drive family. It is designed to control a single motor module (e.g., PM340) and communicates with the higher‑level controller via an integrated PROFINET interface with two ports (IRT). The unit is hot‑pluggable, requires firmware V4.4 or higher, and is delivered without a CompactFlash card. A CF card must be ordered separately and inserted before commissioning.

Applications

• Positioning tasks in packaging, printing and converting

• Single‑axis servo control for pick‑and‑place and handling systems

• Speed and torque control for conveyor drives

• Cam and synchronous operation in production lines

• Motion control for machine tools and robotics

Key Features

• PROFINET IRT interface with two‑port switch, 250 µs cycle time

• DRIVE‑CLiQ port for direct connection to Power Modules and motors

• Integrated encoder evaluation (TTL, HTL, SSI)

• 11 digital inputs, 8 bidirectional digital I/O, 1 analog input

• Hot‑pluggable design, firmware upgradeable from V4.4

• Safety Integrated (STO) via terminal – higher safety functions require CU310‑2 F‑module

• Order and install CF card separately (6SL3054‑0xxxxx‑0AA0)
