More Information

Overview Manuals Drive Paths Encoder Channel Memory Card Version Boundary

Features:

  • The C240 controller coordinates PROFIBUS, analog, and stepper-drive connections from one SIMOTION unit.
  • Eighteen digital inputs and eight digital outputs bring local discrete signals directly into the controller.
  • The SSI feedback channel monitors both encoder-supply short circuits and signal-wire breaks.
Siemens 6AU1240-1AA00-0AA0 separates local machine states from the drive paths: discrete signals use onboard I/O while motion connections follow their dedicated interfaces.

The SSI channel of 6AU1240-1AA00-0AA0 powers compatible feedback devices and changes its allowable cable reach with the selected transmission rate.

Software and memory-card matching are part of the 6AU1240-1AA00-0AA0 configuration because the supported card boot loader follows the SIMOTION release.

The Siemens 6AU1240-1AA00-0AA0 SIMOTION C240 Motion Controller may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
Siemens 6AU1240-1AA00-0AA0 SIMOTION C240 Motion Controller Manuals,Datasheets,Link 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.

How command paths divide

  • PROFIBUS drives: Cyclic drive communication uses the controller's PROFIBUS connection rather than the local I/O bank.
  • Analog drives: Analog command paths remain distinct from the networked drive route.
  • Stepper drives: Pulse-based stepper control uses the C240 hardware assigned to that drive type.
  • Local signals: The 18 inputs and 8 outputs serve machine states and commands without replacing the drive interfaces.

SSI feedback relationship

  • Feedback format: The synchronous-serial channel accepts single-turn or multi-turn SSI encoders.
  • Channel power: The same interface supplies the documented 24 V encoder feed at up to 0.3 A.
  • Rate and distance: Higher SSI transfer speed shortens the permitted cable run, from 250 m at 187.5 kbit/s to 10 m at 1500 kbit/s.
  • Circuit checks: Short-circuit monitoring covers the sensor supply, while wire-break monitoring covers the feedback path.

Card and kernel matching

  • Project medium: Controller project and boot information are held on a compatible SIMOTION Micro Memory Card.
  • Card choices: The C240 documentation lists 32 MB and 64 MB card order numbers for this hardware family.
  • Boot loader: The card boot-loader level must support the SIMOTION kernel loaded for the controller.
  • Release check: A card suitable for one C240 release should not be assumed to cover every later kernel without verification.

Starting software condition

  • Initial release: The listed operating baseline for this order number is SIMOTION V4.0 HF2.
  • Project alignment: Controller hardware, SIMOTION project version, and memory-card boot files must describe the same supported release.
  • Card compatibility: Later controller kernels require the corresponding tested card and boot-loader assignment.
  • Commissioning record: Recording the installed kernel and card order number prevents version ambiguity during replacement.
Description
Siemens 6AU1240-1AA00-0AA0 is a SIMOTION C240 programmable motion controller in the controller-based SIMOTION C platform. It executes motion and automation functions while connecting PROFIBUS, analog, and stepper drives to one controller.

Eighteen digital inputs and eight digital outputs place local machine signals directly on 6AU1240-1AA00-0AA0. The discrete channels handle status and command points at the controller, while the separate drive interfaces carry the motion-related connections.

Encoder feedback on 6AU1240-1AA00-0AA0 includes an SSI path for 5 V synchronous-serial single-turn or multi-turn encoders. The controller supplies 24 V at 0.3 A to that encoder circuit, accepts four documented transmission rates from 187.5 to 1500 kbit/s, and checks the sensor supply for short circuit and the signal path for wire break.

The operating configuration of 6AU1240-1AA00-0AA0 begins with SIMOTION V4.0 HF2. Project and boot data reside on a compatible SIMOTION Micro Memory Card; the listed 32 MB and 64 MB cards use device- and kernel-specific boot-loader assignments, so the installed software release and card type must be matched together.

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.
How can I distinguish 6AU1240-1AA00-0AA0 from the C240 PN version?
Siemens 6AU1240-1AA00-0AA0 is the C240 for PROFIBUS, analog, and stepper drives; the separate PN order number identifies the PROFINET variant.
What should be checked before moving an existing memory card into 6AU1240-1AA00-0AA0?
Match the SIMOTION release, card order number, and boot-loader version for 6AU1240-1AA00-0AA0 before startup.
Why does the allowed SSI cable length change on 6AU1240-1AA00-0AA0?
The 6AU1240-1AA00-0AA0 limit follows the selected transfer rate: 250 m is listed at 187.5 kbit/s and 10 m at 1500 kbit/s.
Does 6AU1240-1AA00-0AA0 require a separate front connector for onboard I/O?
Yes. The 18 inputs and 8 outputs of 6AU1240-1AA00-0AA0 use the documented 40-pin front-connector options.
Which feedback faults can 6AU1240-1AA00-0AA0 detect on the SSI path?
The 6AU1240-1AA00-0AA0 monitors encoder-supply short circuit and feedback wire break.
What supply should be verified at the 6AU1240-1AA00-0AA0 controller?
Verify the documented 24 V DC controller supply for 6AU1240-1AA00-0AA0 and keep the encoder feed within its separate 0.3 A limit.
