More Information

Overview Manuals Keys & Overrides Ethernet Setup User I/O Panel Mounting

Features:

  • Forty-nine mechanical keys with LEDs place machine functions on a physical operator surface.
  • Separate rear connections carry Ethernet, DC supply, customer-key signals and handwheel inputs.
  • The front and rear have different protection ratings, defining the cabinet mounting boundary.
Mode selection, program functions and feed override share the mechanical control face of 6FC5303-0AF23-0AA1.

Inputs from customer switches are not the same as the lamp-driving outputs; those two paths use different rear connectors.

The rear clamps secure the panel in its cutout, leaving the front accessible to the operator and the unprotected rear inside the cabinet.

The Siemens 6FC5303-0AF23-0AA1 SINUMERIK MCP 310C PN Machine Control Panel may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Machine command hardware

  • Short-stroke keys: Each mechanical key has an associated LED for operator feedback.
  • Customer keys: Sixteen of the front keys are available for machine-specific assignments.
  • Feed override: The multi-position rotary switch changes the selected feed or rapid-traverse override command.
  • Key switch: The four-position switch provides a separate keyed operating selection.

Port and device-name behavior

  • X20/X21: Two rear Ethernet ports provide the panel's network connections.
  • S2 mode: The switch positions select IE or PROFINET behavior, with IE set on delivery.
  • PN names: In PROFINET mode, address switches can establish a default device name.
  • DCP mode: When no default name is selected, the device name is assigned by initialization and stored on the panel.

Switches, lamps and handwheels

  • Passive inputs: X51, X52 and X55 accept customer switch contacts.
  • Lamp outputs: X53 and X54 drive customer-button lamps rather than inductive loads.
  • Handwheel sockets: X60 and X61 provide separate D-sub connections for two handwheels.
  • Signal selection: S1 determines whether the handwheel input uses TTL or differential signaling.

Front opening and rear services

  • Cutout: The housing fits the specified panel opening and clamps from the rear.
  • Front protection: The IP54 front remains on the operator side of the installation.
  • Rear protection: The IP00 rear stays inside a suitable enclosure.
  • Temperature split: Siemens specifies different operating limits for the front and rear of the installed panel.
Description
The SINUMERIK MCP 310C PN machine control panel, Siemens 6FC5303-0AF23-0AA1, places mechanical operating keys, program controls and feed override where the operator enters machine commands.

At the front of 6FC5303-0AF23-0AA1, short-stroke keys have assigned LEDs, while the feed override uses a multi-position rotary switch. The key-operated switch and replaceable key covers serve different tasks: switch-position selection and machine-specific key labeling.

The rear of 6FC5303-0AF23-0AA1 separates 24 V DC power at X10 from Ethernet at X20 and X21. S2 selects the panel's IE or PROFINET behavior; in PN mode, its address settings define the default device name unless DCP mode is chosen.

Customer switches connect to the input connectors of 6FC5303-0AF23-0AA1, while dedicated outputs drive lamps in the corresponding buttons. Two separate D-sub connectors accept handwheels, with switch S1 selecting TTL or differential signals for that connection.

Technical notes
Mechanical keys, a 23-position feed-override switch and separate customer I/O make Siemens 6FC5303-0AF23-0AA1 a local command panel; its rear X20/X21 ports carry Ethernet.

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.
Why does 6FC5303-0AF23-0AA1 not appear as a PROFINET panel after connection?
The S2 mode switches on 6FC5303-0AF23-0AA1 must be set for PN operation; the delivered IE setting does not by itself enable the PROFINET device-name behavior.
How is a default PROFINET device name set on 6FC5303-0AF23-0AA1?
With 6FC5303-0AF23-0AA1 in PN mode, S2-1 through S2-8 select a documented default device name; DCP mode instead requires an initialization procedure.
Can a valve be connected to the customer outputs of 6FC5303-0AF23-0AA1?
No. The X53/X54 outputs on 6FC5303-0AF23-0AA1 are intended to drive button lamps; Siemens warns against connecting relays, valves or other inductive loads.
Which rear sockets on 6FC5303-0AF23-0AA1 accept optional switch contacts?
Passive customer switches connect to X51, X52 or X55 on 6FC5303-0AF23-0AA1; the separate X53/X54 connectors serve lamp outputs.
What must be selected before wiring a handwheel to 6FC5303-0AF23-0AA1?
The handwheel signal type on 6FC5303-0AF23-0AA1 is set at S1 to TTL or differential before using rear sockets X60/X61.
Does the front IP54 rating of 6FC5303-0AF23-0AA1 cover rear wiring?
No. Siemens rates the front of 6FC5303-0AF23-0AA1 IP54 but the rear IP00, so the rear connections require the enclosure side of the installation.
