B&R 3NC150-6

Product Type: 3-Axis CNC Motion Controller

Product Description:
The B&R 3NC150-6 is a 3-axis CNC controller from B&R’s NC product line. It provides full numerical control for milling, drilling, cutting, and routing operations with integrated motion control, PLC, and HMI functionality. It runs the B&R NC runtime software and is designed for integration into B&R Power Panel systems or standalone CNC machines.

  • Dimensions (Controller Module): Approximately 150 mm × 100 mm × 50 mm (varies by mounting)
  • Weight: Approximately 0.8 kg (controller module only)

Functional Features:

  • G-code interpreter (ISO 6983 / DIN 66025 compatible)
  • M-code macro programming for custom functions
  • Tool compensation: Tool length offset (G43), Tool radius compensation (G41/G42)
  • Work coordinate systems: G54 to G59 (6 work offsets)
  • Spindle control: S-speed command, M03/M04/M05, orientation (M19)
  • Programming methods: Manual data input (MDI), program editor, DNC (network transfer)
  • B&R NC HMI visualization for machine operation
  • Electronic camming and gearing for synchronized multi-axis motion

Structural Characteristics:

  • Compact DIN rail mountable module (35 mm TS rail)
  • Front panel with status LEDs and MPG/jog connector
  • RJ45 Ethernet, DB9 RS-232, USB-B connectors
  • Terminal blocks for axis encoder feedback, limit switches, spindle control
  • RoHS compliant construction

Material Composition:

  • Housing: Aluminum die-cast with anodized finish
  • PCB: FR-4, multi-layer, conformally coated
  • Connectors: Gold-plated pins, MIL-spec quality

Applicable Industries:

  • Milling machines (3-axis vertical/horizontal)
  • Drilling and tapping centers
  • Routing and engraving machines
  • Laser cutting (3-axis)
  • Waterjet cutting (3-axis)
  • EDM (Electrical Discharge Machining)

Installation Requirements:

  • Mount on DIN rail TS 35 inside Power Panel or separate control cabinet
  • Encoder cables (incremental, 1 Vpp RS-422) must be shielded and grounded at one end
  • Limit switch wiring: normally closed (NC) safety configuration recommended
  • Spindle drive connection: analog 0-10 V or PWM signal
  • Ensure proper earthing of all metallic machine parts

Usage Notes:

  • Perform axis homing (reference return) before first operation — G28 command
  • Do not exceed maximum look-ahead block count — causes path deviation
  • Backup CNC programs to external storage daily — programs are stored in volatile memory by default
  • Servo tuning must be performed by qualified personnel — incorrect gains cause oscillation or following error
