Detailed description of the invention
One, type selecting purchase Siemens analog input module SM334, job number is 6ES7-0CE01-0AA0 mono-piece (if equipment rack has Analog input mModule, just not needing to have installed again), precision current transformer DL-CT08CL5 mono-.
Two, according to Fig. 3, a power line of the output of the relay K M8 of the control chip cleaner in Digit Control Machine Tool power distribution cabinet overlaps precision current transformer DL-CT08CL5.
Three, the passage three (12 pin and 13 pin) of two feedback lines to Analog input mModule SM334 of precision current transformer DL-CT08CL5 is connected, communication module IM361 is connected to by the communication interface of Analog input mModule SM334, communication module IM361 is connected with 840D digital control system NCU and digital output module SM322 respectively, and digital output module SM322 is connected with chip cleaner relay.
Four, set in CNC Machine Tools work main program OB1 and add following program:
The first step, it is that one by one after second, timer T30 is 1, judges the actual current value IW326 of chip cleaner motor and the relation of setting value by compare instruction CMP>I that chip cleaner rotates forward Q48.0.
Second step, if when the actual current value IW326 of chip cleaner motor is greater than setting value, then reset Q48.0, set Q48.1.Chip cleaner reversion Q48.1 is one by one after second, then judges the actual current value IW326 of chip cleaner motor and the relation of setting value.If when the actual current value IW326 of chip cleaner motor is less than setting value, then chip cleaner normally works.
3rd step, if during chip cleaner reversion, when the actual current value IW326 of chip cleaner motor is greater than setting value, then reset Q48.0, Q48.1, set DB2.DBX187.0, makes the display of digital control system show No. 700056 warnings " chip cleaner fault please check whether foreign matter or other faults ".Press the reset key I3.7 on machine tools control panel, can reset No. 700056 and report to the police.
4th step, if during chip cleaner reversion, when the actual current value IW326 of chip cleaner motor is less than setting value, then time delay is after 5 seconds, set Q48.0, reset Q48.1.It is one by one after second that chip cleaner rotates forward Q48.0, then judges the actual current value IW326 of chip cleaner motor and the relation of setting value.
5th step, if when the actual current value IW326 of chip cleaner motor is greater than setting value, then perform the action of the first step, this hour counter T67 counts once, after action repeats 3 times, counter T67 is one, reset Q48.0, Q48.1, set DB2.DBX187.0, makes the display of digital control system show No. 700056 warnings.If when the actual current value IW326 of chip cleaner motor is less than setting value, then chip cleaner normally works.
Five, field adjustable.
The course of work is as follows:
When the chip cleaner work of lathe, the electric current of motor is gathered by precision current transformer DL-CT08CL5, be sent to Analog input mModule SM334, by communication module IM361, data are sent in the NCU of digital control system, when current value is greater than the value of setting, illustrate that the chip cleaner of lathe has foreign matter or solid accumulation to cause the stall of motor, at this moment the NCU control figure amount output module SM322 of digital control system
Output point Q48.0=0, Q48.0=1, the auxiliary reclay KA0 dead electricity that chip cleaner is rotated forward, the auxiliary reclay KA1 of chip cleaner reversion obtains electric, the A.C. contactor KM8 dead electricity that chip cleaner rotates forward, the A.C. contactor KM9 of chip cleaner reversion obtains electric, after 5 seconds, the output point Q48.0=1 of the NCU control figure amount output module SM322 of digital control system, Q48.0=0, the auxiliary reclay KA0 that chip cleaner is rotated forward obtains electric, the auxiliary reclay KA1 dead electricity of chip cleaner reversion, the A.C. contactor KM8 that chip cleaner rotates forward obtains electric, the A.C. contactor KM9 dead electricity of chip cleaner reversion, if the current value detecting motor is less than the value of setting, then chip cleaner normally works, if the current value detecting motor is still greater than the value of setting, then repeat reversion, rotate forward, until chip cleaner is normal, if the chip cleaner current value that still cisco unity malfunction or chip cleaner detect motor when reversing is greater than the value of setting after three times, then " the chip cleaner fault of display alarm in digital control system, foreign matter or other faults please be check whether ", chip cleaner motor stall, prevent motor stall or damage mechanical part.
