PMAC full name but process designing much axle control implement (ProgrammableMulti-AxisController) , it is the is based on PC platform open mode that American DeltaTauDataSystems company rolled out 1990 athletic controller. Control of its market movement and PLC are controlled at an organic whole, have the real time such as outstanding interpolation computation, servo and I/O interface to control capacity, most controallable 32 axes (TurboPMAC) . Board the MACRO interface that go up allows to get stuck a lot of PMAC couplet to undertake controlling into annular net. It supports a variety of bus line standards (ISA, PCI, VME and STD) , same control software moves on OK and diverse bus line, offerred much platform to support character thereby. PMAC still supports a variety of electric machinery (if shed servo electric machinery, communication continuously,synchronous electric machinery, communication asynchronous electric machinery, pace enters electric machinery, linear electric machinery) and detect feedback component (increment coder, absolutely coder, rotate sensor of transformer, linear magnetism) . PMAC is CPU with Motorola56000 series DSP, board the memory that go up is used at depositing a system to control interface of software and user program, I/O and servo interface to be used at join exterior input / output signal and servo electric machinery, board the indication interface that go up allows link a 2 × the character LCD of 40. This calorie of itself is system of a NC can be used alone, in also can inserting a PC, form open mode to control a system, following plan institute show its hardware structure, next watches open the main specifications index of type exercise controller for PMAC. TURBO-PMAC of main specifications index dominates the main specifications index that exercise of graph PMAC open type dominates calorie of watch to open type exercise controller number of axle 32 passageways structure (coordinate is fastened) 16 linkage number of axle 32 interpolation (linear, circular arc, corkscrewed yarn) have blame is even justifiable batten interpolation (NURBS) has 3 rank multinomial, 100 block handle ability 1000 paragraphs / cent is forecasted (LookAhead) control of the make a present of before the function has speed and acceleration has S curve to add decelerate control to synchro control function has cutting tool radius and length compensation to compensation of guide screw pitch error has high speed position to collect have electronic gear and electronic cam programming language RS274 and, but all sorts of communication, dc, pace takes drive, 64 PLC are installed inside ability of PLC of linear electric machinery (real time PLC, had compiled the PLC that carries out again, the PLC that the explanation carries out) CNC MillingCNC Machining
