Description

The 6SL3040-1LA00-0AA0 is a control unit from the Siemens SINAMICS S120 drive system family, designated as the CU310-2 DP. It is a single-axis control module designed for operation connected to a Power Module in blocksize or chassis formats, implementing all open-loop and closed-loop control functions for one motor drive.

The control unit operates from a 24 V DC electronics power supply with a permissible range of 20.4 to 28.8 V DC. Current consumption is 0.8 A without DRIVE-CLiQ and digital outputs. Maximum power loss is less than 20 W. The unit is hot-pluggable and requires firmware version V4.4 or higher, stored on a separately ordered CompactFlash card (6SL3054-0EE00-1BA0).

Eleven isolated digital inputs accept -3 to +30 V DC signals with 50 µs typical delay for low-to-high transitions and 150 µs for high-to-low transitions. Eight bidirectional digital inputs/outputs are non-isolated and configurable per application. Four of these (DI/DO 12–15) are rapid inputs with 5 µs delay, usable as probe inputs or external zero mark inputs. As outputs, they provide 24 V DC at 500 mA maximum per channel with short-circuit, ground fault, and overload protection.

Features:

  • SINAMICS S120 CU310-2 DP control unit
  • PROFIBUS DP communication interface
  • Integrated DRIVE-CLiQ connection
  • 24 VDC power supply
The Siemens 6SL3040-1LA00-0AA0 is a SINAMICS S120 CU310-2 DP Control Unit developed for high-performance single-axis motion control within the SINAMICS S120 modular drive platform. The unit performs drive control, communication management, encoder processing, diagnostics, and parameter handling while coordinating the operation of connected power modules and motors. It is supplied without a CompactFlash memory card, allowing users to install the required memory card separately according to the application.

The control unit features an integrated PROFIBUS DP interface for communication with PLCs and higher-level automation systems. A built-in DRIVE-CLiQ interface enables direct connection to compatible motors, encoder systems, and Siemens drive components, supporting automatic device identification and efficient parameter exchange throughout the drive system.

The 6SL3040-1LA00-0AA0 SIEMENS SINAMICS S120 control unit CU310-2 DP may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.
For machine interfacing, the CU310-2 DP provides 11 digital inputs, 8 configurable digital I/O channels, and one configurable analog input supporting either voltage (±10 V) or current (±20 mA) signals. These integrated interfaces allow direct connection of sensors, switches, command signals, and process feedback devices without requiring additional interface hardware for many standard motion applications.
 
The onboard encoder interface supports TTL, HTL, and SSI encoder technologies with encoder frequencies up to 300 kHz and absolute encoder resolutions up to 30 bits. These capabilities provide accurate position, speed, and motion feedback for servo systems used in demanding industrial automation equipment.

Grounding (PE): Always connect the protective earth (PE) using the M5 screw located at the bottom of the unit. Use a braided shield with a maximum cross-section of 6 mm² (AWG 10) to prevent electromagnetic interference.
Electronics Power Supply: Connect a regulated 24V DC supply (tolerance: 20.4V to 28.8V) to the top 2-pin connector. The maximum conductor cross-section is 2.5 mm² (AWG 14).
Communication & Encoder: Connect your PROFIBUS cable to the designated Sub-D port and your DRIVE-CLiQ cable to the Drive-CLiQ port for communication with the Power Module and encoders

Technical notes

Communication interfaces include one PROFIBUS DP port (X21) for integration into automation networks, one RS232 serial interface (X22) for commissioning and service, one DRIVE-CLiQ interface (X100) for connection to Power Modules and motor modules, and one LAN Ethernet port (X127) with Auto MDI(X) support for web server access and engineering.
