The pace enters electric machinery with its price price of reasonable, sex compares tall, control to go to the lavatory in waiting for an advantage to already waited for Electromechanical unifinication equipment in the machine tool, got applied extensively. The signal such as the pulse that the pace must rely on power source of controller, drive to offer into electric machinery finishs litre of frequency, fall frequency, speed, gearshift, stop, wait for the job reversely, the standard that controls power supply of circuit, drive so is deciding a pace to run function and stability into electric machinery. And how making dominate simpler, convenient, economy is another when the pace uses a field into electric machinery main task. Current, very big equipment of unifinication of a batch of Electromechanical, machine tool equipment and automation production facilities used PLC control, among them one part function needs to use a pace to dominate drive program into electric machinery servo. For example: Need implementation is much fast, the feed control of much journey or auxiliary control (self-correcting of grinding feed, emery wheel) circumstance. PLC itself does not have output of high speed pulse, the add intelligence that wants to increase to control form a complete set into electric machinery with the pace on the foundation of PLC for this controls module. This module increases the drive power supply that brings fractionize, the cost of whole control part is higher, restricted a pace to be used into the promotion of electric machinery driver. To overcome afore-mentioned problems, hill company electric machinery supplied product of drive of a kind of new-style control, it makes full use of odd all sorts of resource of a machine and traversal speed are advanced characteristic, fulfil all sorts of hardware functions and other function with software, command the stage module and drive power source to close into electric machinery 2 for one. Its hardware circuit gets simplifying, cost is reduced greatly, bulk is cabinet at the same time, install and use convenient. Apply to the 2 photographs, Composite pace that is not more than 3A extensively to enter electric machinery (80 series and the following) of each series electric machinery. Control drive is core with the current and popular ATM89C51 that takes 4KFLASHROM oneself, if the graph is shown 1 times, include the module such as enlarge of changeover of input, D/A, power. This the biggest characteristic that controls drive depends on software changing. Finish through software a few more the following main function: Input scanning, litre fall cent of annulus of pulse of frequency, software and synchronization / fractionize switch. Odd a machine receive the n signal that comes from mouth of 4 exterior inputs: One uses at controlling direction: The others is used 3 times at controlling rate, their different combination can choose 7 kinds of commonly used running frequency and suspend restoration status (show) like subordinate list place. Finish automatically litre fall frequency, synchronization / the job such as fractionize switch, output the pulse after annulus is divided. CNC Milling
