Siemens 6SL3040-1MA00-0AA0 SINAMICS S120 CU320-2 DP Control Unit
Multi-axis SINAMICS Control Unit with PROFIBUS DP, four DRIVE-CLiQ interfaces and configurable machine I/O.
01Overview
Siemens 6SL3040-1MA00-0AA0 is the SINAMICS CU320-2 DP Control Unit for coordinated drive systems using PROFIBUS DP. It provides four DRIVE-CLiQ interfaces, extensive onboard digital I/O, an Ethernet service interface and an option-module slot. The unit is delivered without a CompactFlash card, so firmware, licensing and the complete S120 topology must be matched to the installed machine before commissioning or replacement.

04Applications
- Multi-axis machines that retain PROFIBUS DP as the higher-level fieldbus.
- SINAMICS S120 booksize or chassis systems coordinated by one CU320-2 DP.
- Retrofit or maintenance work requiring the exact PROFIBUS Control Unit variant.
- Drive cabinets using DRIVE-CLiQ motor, line and sensor modules.
- Industrial machinery requiring coordinated motion, diagnostics and parameter management.
05Lifecycle
- Siemens lists the CU320-2 DP article as an active product.
- Order and verify the compatible CompactFlash card because it is not included.
- Archive the complete drive project, topology, firmware, licenses and PROFIBUS settings before removal.
- Match all option boards, terminal functions, Safety Integrated settings and DRIVE-CLiQ components.
- Commission each axis and validate PROFIBUS communication, feedback, limits and coordinated machine sequences.
06FAQ
Which network differentiates 6SL3040-1MA00-0AA0 from the PN version?
This article is the CU320-2 DP variant with a PROFIBUS DP interface.
How many DRIVE-CLiQ interfaces does the CU320-2 DP provide?
The official technical data lists four DRIVE-CLiQ connections.
What onboard digital channels are available?
It provides twelve digital inputs and eight bidirectional channels that can be parameterized as inputs or outputs.
Does the CU320-2 DP contain the operating firmware card?
No. The Control Unit is supplied without the CompactFlash card required for firmware and licensing.
What auxiliary supply is required by the controller?
It uses 24 V DC within the documented 20.4 to 28.8 V range, with maximum current consumption of 1.0 A.
Which records should be retained when replacing a DP controller?
Retain the drive archive, CompactFlash data, PROFIBUS address and telegram settings, topology, options, safety configuration and all axis parameters.
