Compact Numeric CNC controllers

The compact CNC controllers 905 and 903 are the economical and cost-efficient solution for simpler applications to control up to 8 axes.

Functions

The controller communicates via the CAN bus with the drives and the binary inputs and outputs (I/O). The CNC 902…905 offer:

• Real-time operating system
• CNC system
• Integrated PLC
• Protocols: ACC (CANopen), TCP/IP
• Programming of user interface with PROMA
• Block-by-block reloading for larger programs
• Graphical cyclical programming
• Free DLL for implementing own programs

The following CNC functions can be mapped:

• Linear interpolation in all axes
• Circular interpolation in all axes 2 1/2D and 3D
• Helical interpolation in 2+1 axes
• Spline interpolation
• Polynomial interpolation
• Tangential axis
• Coupling, mirroring and exchanging axes
• Repositioning after cancellation
• Feed, corner, circle and contour dynamics
• Electronic gearbox
• Handwheel
• Polar coordinate system
• Polar transformation
• Axes simulation
• Rotating, mirroring and moving coordinates
• Measuring and processing cycles
• Interpolation levels
• Tool radius path correction
• Automatic selection of linear and circular interpolations
• Zero points / zero offset
• Quick contour definition programming
• Parameter calculation
• Diagnostics functions
