Abstract
A kind of method using program analog inverter control trolley travelling disclosed by the invention, it is characterized in that, when trolley is when start bit starts, as soon as the PLC program triggering counter of control motor operation starts pulse timing and compares, the every frequency by changing PLC for 0.2 second to mono- band frequency of PLC of the counter；When trolley touches deceleration position or just starts to accelerate, frequency converter frequency is changed in the 0.2 second time of precision by the comparison of counter number, realizes the high-precision control of motor.The present invention is not wasting PLC preciousness points, and is able to satisfy the uniform acceleration and deceleration requirement of trolley, improves the reliability, stability and safety of trolley travelling.
Description
Technical field
The present invention relates to the trolley travelling control technology fields in high-speed multifunctional bale breaker, in particular to a kind of to utilize journey
The method of sequence analog inverter control trolley travelling.
Background technique
The trolley travelling in high-speed multifunctional bale breaker generally uses traditional frequency conversion device to be controlled at present.And traditional frequency conversion
Device provides the control of multi-speed band frequency and Acceleration and deceleration time control.In high-speed multifunctional bale breaker, when generally trolley being required to start
Quickly to accelerate, such traditional frequency conversion device can be reached by reducing the acceleration time.Such as when trolley arrival stop position, in order to reach
Stop to accurate, the deceleration time of traditional frequency conversion device can be arranged very low even zero, stop even add in the case where shakiness
Included DC injection braking function.But in acceleration and deceleration, in particular up to deceleration position, since acceleration and deceleration setting has been opened to meet
Dynamic and stop position can only just use multi-speed section trolley can be made gradually to slow down.The most 15 section speed of band of general traditional frequency conversion device, and
15 section speed switchings inherently consume PLC output point.Modern electrical machine requires high-precision control, 15 section speed of traditional frequency conversion device
The case where being far from satisfying the requirement of stable acceleration and deceleration, or even having will appear motor vibrating.Therefore some enterprises are with more
Accurate stable servo motor, but price is considerably beyond traditional frequency conversion motor.
Summary of the invention
Technical problem to be solved by the present invention lies in the requirement for being unable to satisfy stable acceleration and deceleration for traditional frequency conversion device
One kind is provided and is not wasting PLC preciousness points, and the utilization program analog inverter control for being able to satisfy the uniform acceleration and deceleration of trolley is small
The method of vehicle operation, can increase the reliability, stability and safety of trolley travelling.
The technical problems to be solved by the invention can be achieved through the following technical solutions:
A method of trolley travelling is controlled using program analog inverter, characterized in that when trolley starts in start bit
When, PLC program one counter of triggering for controlling motor operation starts pulse timing and compares, and the counter is every to be passed through 0.2 second
Just change the frequency of PLC to mono- band frequency of PLC；When trolley touches deceleration position or just starts to accelerate, pass through counter
The comparison of number changes frequency converter frequency in the 0.2 second time of precision, realizes the high-precision control of motor.
Due to using technical solution as above, the present invention is not wasting PLC preciousness points, and is able to satisfy trolley and uniformly adds
Deceleration demand improves the reliability, stability and safety of trolley travelling.
Detailed description of the invention
Fig. 1 is operation of the trolley between starting bit, deceleration position, stop position and limit position in high-speed multifunctional bale breaker
Schematic diagram.
Specific embodiment
The present invention is further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, trolley 100 in high-speed multifunctional bale breaker shown in figure in starting bit 200, deceleration position 300, stop
Operation between stop bit 400 and limit position 500.
Quickly accelerate frequency converter deceleration time can not influenced motor overload shake feelings first of all for trolley 100 is met
What be can be set under condition is very low, and in order to meet trolley, in zero-speed, quickly deceleration time can not influenced motor overload by parking
What be can be set under jitter conditions is very low, stops adding included DC injection braking function in the case where shakiness.
After above-mentioned basic setup, PLC can be used in frequency converter program from tape pulse.Usually major PLC is minimum
Can be with 0.1 second interval, using 0.1 second pulse-triggered PLC from tape counter, such counter can start from scratch every 0.2
Second plus 1, the precision of counter are 0.2 second.Think any time when trolley 100 touches deceleration position 300 or just starts acceleration etc.
When changing frequency converter frequency, frequency converter frequency can be changed in the 0.2 second time of precision by the comparison of counter number, from
And reach high-precision control.
For example when trolley 100 is when starting bit 200 starts, program flip-flop number starts pulse timing and compares, and works as meter
It when number device is 1, that is, have passed through 0.2 second, give a band frequency, one band frequency of frequency converter can be given every 0.2 second backward,
Highly uniform deceleration can be accomplished in the process by accelerating to deceleration position 300, similarly be slowed down in deceleration position 300, stop position 400 stops
Frequency conversion precision can be improved.
