01Overview

Siemens 6SL3040-1NB00-0AA0 is the SINAMICS Numeric Control Extension NX15.3. It extends compatible SINUMERIK ONE, SINUMERIK 840D sl and SINUMERIK 828D drive-control configurations by up to six axes. The module operates from a 24 V DC electronics supply and provides six digital inputs plus four parameterizable digital inputs or outputs. Compatibility depends on the exact NCU or PPU, software version, DRIVE-CLiQ topology and permitted number of NX extensions.

03Features

Key Functions

  • Extends compatible SINUMERIK drive control by as many as six axes.
  • Provides six digital inputs and four parameterizable digital input/output channels.
  • Integrates into the CNC drive topology as an NX15.3 rather than a standalone controller.
  • Uses a 24 V DC PELV electronics supply within the documented tolerance.
  • Employs open-circuit ventilation and an IP20 cabinet-mount design.
  • Supports system expansion only within the NCU or PPU configuration limits documented by Siemens.

Product Identity

  • Manufacturer: Siemens
  • Model: 6SL3040-1NB00-0AA0
  • Product Type: SINAMICS NX15.3 drive-control extension
  • Status: Active product

04Applications

  • Axis expansion for SINUMERIK ONE NCU or PPU systems.
  • Additional drive-control capacity in compatible SINUMERIK 840D sl installations.
  • SINUMERIK 828D machines requiring an approved NX15.3 extension.
  • Multi-axis machine tools where the base CNC reaches its direct drive-control capacity.
  • Maintenance replacement of an installed NX15.3 with unchanged topology and software compatibility.

05Lifecycle

  • Siemens lists the NX15.3 article as an active product.
  • Confirm the CNC platform, software release and maximum permitted number of NX modules before expansion.
  • Document DRIVE-CLiQ topology, axis assignments, I/O and the CNC archive before hardware work.
  • Do not confuse NX15.3 with NX10.3, which has a different maximum axis capacity.
  • After installation, restore the approved configuration and validate every added axis, I/O channel, diagnostic and machine function.

06FAQ

How many axes can 6SL3040-1NB00-0AA0 add?

The NX15.3 supports drive control for up to six additional axes in a compatible SINUMERIK configuration.

Which CNC families officially use the NX15.3?

Siemens identifies SINUMERIK ONE, SINUMERIK 840D sl and SINUMERIK 828D as compatible platform families.

What digital I/O is integrated on the extension?

It provides six digital inputs and four parameterizable digital input/output channels.

What electronics supply range is permitted?

The module uses 24 V DC with a permissible range of 20.4 to 28.8 V.

How does NX15.3 differ from NX10.3 in axis capacity?

NX15.3 supports up to six axes, while Siemens documents NX10.3 for up to three axes.

What compatibility checks are essential before adding an NX module?

Verify the exact NCU or PPU, CNC software release, permitted NX count, DRIVE-CLiQ topology, axis licenses, cooling and project archive.
