PC-Posi and Posi conrollers

PC-Posi and Posi conrollers

Our popular and well-known range of CNC control units with WinPC-NC and CNC-Control has be en completed by Posi controllers. Th ese versions are ideally suited for any kind of standard automation tasks and motion controls. Compared with path control systems with look-ahead-function, import filters and graphic display, our Posi controllers offer extremely fast point-to-point movements, a comprehensible clear text programming and a uncomplicated start-up system. CNCPOS and PosiMAX provide a control unit which is ready for operation and equipped with a powerful and efficient industrial PC hardware, an pre-installed operati ng system and the corr esponding PC-Posi software. For the start-up procedure you need nothing but a VGA monitor and a PS/2 keyboard. After finishing the program generation and the start-up procedure all Posi controllers can be handled automatically via external input signals and all tasks are carried out in a steady, stable and reliable mode without involvement of monitor and keyboard. By using our Posi controllers you can realize any kind of handling and robot applications, feed functions, dispensing tasks, format adjustments and any other job without investing significant financial amounts. Due to distinguishing construction forms and equipments the software is most qualified for being used in various application areas. Linking-up serveral control units with mutual synchronisation via digital signals is just as practicable as the integration into larger complete systems and the coupling to PLCs or to additional subordinated controls.

Up to now, the following applications have been realized by us or our customers...

feeding workpieces into erosion machines
three CNCPOS controllers as interconnected system for separating and producing glass pipets with 10 axes to be controlled
dosing and moulding of relay onto a matrix
removing and palletising the produced workpieces from a CNC milling machine
welding frame parts for trucks
automatic solding of control units with base plate for domestic appliances
bending unit with 4 axes for complex wire parts

integrated powerful and efficient soft-PLC with programming comformable to Step5
multiple configurable parts counter
clock times in mill. seconds
programming device, runtime system, test and diagnostic tool and visualization in one unit, no necessity for addtitional programming station or laptop
optionally with serial communication to other components

Easy handling and fast results

The operation of Posi controllers complies with theusual standards and besides drop-down menus, Windows technology and hot keys it also provides an extensive online help which renders assistance whenever required and which supplies useful tips. Programming can easily be understood and simply to be mastered in daily jobs.The included manual is clearly subdivided in categories and gives a detailed and comprehensible description of any kind of programming based on examples.

Creating and starting programs

PC-Posi organizes travelling and sequential programs as well as the corresponding parameters. Each program consists of serveral blocks which are sequentially processed in ,the automatic mode. Creating a program is made by an efficient integrated editor, which has been optimized for fast and confortable service. The program and parameters are saved and they are automatically loaded upon later re-use.

The programming of the integrated Soft-SPS can be compared with Step5 and provides more than 50 commands. Due to 256 inputs of each, outputs, flags and data items it is possible to execute more complex monitoring and controlling tasks which can run parallely to the programmed sequences and movements.

Each record may contain...

absolute or relative distances for each axis
speed in % to max. frequency
repetition counter for record and block repetitions
jump instruction and call for sub program
dwell time at block end
8 outputs which are freely programmable as machine functions
PLC flag for conditional execution or for start synchronisation
additional functions as program stop, counter reset, reset machine and set parts counter

Automatic mode

The automatic processing of the created program is made in stand-alone, continous or in cycle operation mode, i. e. that a start command isresponsible for executing solely one block, a complete program or to carry it out endlessly. Due to complex and time-optimized programming our Posi controllers reach cycle times for a few milliseconds between the program blocks. The reaction time to the start command is also extremely short.

Reference run and manual setting-up

The reference run of the axes is made according to defined order and can be activated by keyboard for a single axis or for all axes. In the jog mode it is possible to move each axis via cursor key in single-step mode or using two speeds which can be setted as required. A comfortable teachin-function allows a new entry or addtional correction of programs.

The user can select various construction types and equipments of our Posi controllers

All controllers include the following components...

efficient industrial PC mainboard with RAM and flash memory for uninterrupted continuous operation
VGA monitor and PS/2 keyboard connection
operating system which is ready for use and installed PC-Posi software licence for 4 axes
16 optocoupled inputs and 8 octocoupled outputs
