Overview Manuals Applications Performance Installation Configuration & Programming

Features:

  • Combines SINUMERIK 840D sl CNC processing with PLC 317-3 PN/DP logic.
  • Provides 2 GB DRAM and manufacturer-defined non-volatile storage.
  • Uses a 24 V DC, twin-fan hardware configuration for machine control.
The complete order code identifies the NCU 730.3B PN spare configuration with integrated PLC and twin cooling fans.

It closes the control loop between CNC interpolation, machine sequencing and connected drives or I/O.

Match software, CompactFlash, licenses, topology and backup sets before selecting or installing another NCU.

This spare-only NCU is supplied after machine configuration and license compatibility are confirmed.
Verified resources for Siemens 6FC5373-0AA30-0AB0:Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Coordinate multi-axis machining and machine auxiliary logic in an 840D sl platform.
  • Exchange real-time control data with SINAMICS drives and PROFINET automation devices.
  • Restore an installed machine controller using validated backups and commissioning records.
  • The NCU executes numerical-control functions and integrated PLC tasks in one unit.
  • Two gigabytes of DRAM provide the documented runtime-memory resource.
  • The 730.3B PN execution is intended for demanding SINUMERIK 840D sl machine configurations.
  • The control unit mounts in the documented 50 x 455 x 272 mm form factor.
  • A twin-fan module provides the cooling arrangement associated with this article.
  • The 24 V supply must satisfy the specified 352 W maximum demand and grounding rules.
  • Machine data and PLC content must be recovered from the validated system backup.
  • CompactFlash data and license assignments belong to the complete machine configuration.
  • Drive and I/O topology must match the restored software before axis enable.
Description
6FC5373-0AA30-0AB0 integrates the SINUMERIK 840D sl numerical-control core and a PLC 317-3 PN/DP in the NCU 730.3B PN execution. The supplied hardware includes the documented twin-fan module and is rated from a 24 V DC source.

Two gigabytes of DRAM support control execution, while 1 MB of non-volatile memory retains the manufacturer-defined persistent functions. The unit coordinates motion, machine logic and networked automation devices within the 840D sl system.

NCU exchange must preserve CompactFlash content, machine data, drive topology, licensing and the integrated PLC project. Mechanical fit alone is insufficient because machine commissioning depends on software versions, option keys and the exact 730.3B PN configuration.

Technical notes
6FC5373-0AA30-0AB0 replacement can immobilize the machine if CompactFlash, license keys or drive topology are mismatched; secure verified backups before power removal.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What control functions are combined inside Siemens 6FC5373-0AA30-0AB0?
The NCU joins SINUMERIK 840D sl CNC processing with an integrated SIMATIC PLC 317-3 PN/DP.
Why is the twin-fan execution relevant when ordering Siemens 6FC5373-0AA30-0AB0?
The exact article includes the documented twin-fan module, so cooling hardware must match the installed NCU configuration.
Which machine data must be secured before Siemens 6FC5373-0AA30-0AB0 service?
Back up the CompactFlash content, machine and drive data, PLC project, topology, firmware records and license information.
How should the 24 V source be assessed for Siemens 6FC5373-0AA30-0AB0?
The supply and cabling must accommodate the documented 352 W maximum active-power demand plus the machine's distribution design.
Can an NCU 710.3B PN replace Siemens 6FC5373-0AA30-0AB0?
No direct equivalence should be assumed because NCU performance, memory, CNC options, software, PLC resources and machine licenses differ.
What identifiers are required for a Siemens 6FC5373-0AA30-0AB0 quotation?
Provide NCU and CompactFlash labels, software version, machine type, option licenses, fan execution, quantity and destination.
