MultiControllerSteuerung - wie ein Orchester

An orchestra served as a model (see picture), there are many paralleles concerning the cooperation, furthermore, this comparison has helped a lot during the development. Perhaps it is helpful for the beginner and for the service-man to understand the controller, too.

The conception for the future must base on modern modules and make use of their technical possibilities. Let us present you our new Multi-Controller conception:

  • Fast and modern 32bit Master - Many ports and interfaces, flexible on a separate board. Functions for security and administration. Flash-Routines for master and slaves to update the firmware when extended.

  • BusSystem for internal communication - Enough slots for future extensions. Up to 8 slaves can be integrated, the software for multiple-axes-operation is and will be developed accordingly.

  • Independent slaves with performance endstep - Up-to-date 8bit-Controllers as AxisControllers with Intelligence on-site. Output stage for the motor control up to 2,5 A. For bigger currents an external output stage is used.

  • Flexible energy supply - Power supply, transformator and distribution for small and big performances.

A big technical progress
especially in the following points:

  • Microstepping for smooth operation and "soft" movements

  • High feed speeds through modern and helpful software modules

  • Short machining times through "fluid" movements

  • Extended range of applications through a big number of possibles axles

The software is and remains the familiar CAD/CAM-programme with direct machine control nccad, which will be delivered together with the MCS from version 7.5 upward in different types. The manual operation window of this version shows some noteworthy functions:

  • More than 4 axes.

  • Enlargened and extended position display with free colour selection (fore-/ background).

  • Switch of the manual operation mode (continuous, as before or in jumps of 3 different widths).

  • Switch of the setting mode for the WZP with/without correction of the radius.

  • Switch of the manual operation to handwheel or JoyStick via key.

  • Many relays, with fields for free names.

  • Direct input of the analogue control tension with free name.

  • Direct speed- and rotation-direction-control of the machining unit (if you have one of the kind) with direct input of rpm. In this case, it is not necessary to convert control tension into revs.

Flexible combinations

Flexible number of axles

You can choose between 1 to 7 AxisControllers and assign them; for example, for controlling a CNC-lathe you need the AxisControllers X and Z, and perhaps also the AxisController U for the tool changer.One of the AxisControllers can be ordered as SpindleController. When the stepping-motor-driven spindle then rotates around the Z-Axis, it is called C-Axis - thus offering a lot of undreamt-of applications (more details under machining unit/C-Axis).
Integration of electronic handwheels
Each main ais can have an optional handwheel. Its handling is just optimal for a mechanic - he can work as usual, in good old tradition.
Axis control via JoyStick
A very comfortable alternative as option, e.g. for quick TeachIn-Programming.
Way-Measuring system for the main axes
Different methods can be integrated optionally. The AxisControllers get the relating intelligence. You need to consult us for this choice, clear ideas about accuracy and resolution are important
Selection of the communication port
RS232 (COM resp. serial) or USB are available. On customer's request, a CAN-linkage can be realized. Selection of the ports and connections for future extensionsThey can be integrated at once, to prevent costs for sending back and forth. If you e.g. intend to equip your control with handwheels later, you should order cables and sockets for it with your first order. Updating the FirmwareAll used controllers are flashable - also on-site by the means of the PC-Software.

The KOSY-MultiController can be delivered for an incredibly wide range of price. The different components are described on separate pages. Go into details.
