Hello In this video we are continue to Delta plc pulse commands as PLSR/DPLSR command 1
that 2
We are going to learn today with this command pulses is or are produced with acceleration and deceleration 3
time. 4
This is the first important thing of this command. 5
The second one this command is used to generate ramp pulses. 6
This is the first important. 7
This is the second important point here. 8
The command usage dplsr 500 D0 3000 y1 five hundred is maximum speed 9
value and it equals five hundred has this zero pulse output number or this is our output name is like 10
Y1 or Y0 an etc. it must be the zero must be minimum of one hundred and ten otherwise it won't 11
work correctly K3000 acceleration and deceleration time. 12
This is three thousand ,three thousand milliseconds and it equals three seconds maximum it could be five 13
thousand milliseconds so it can be five seconds as maximum y1 is it assigned pulse output port in here 14
also you can see structure of the plsr command plsr S1-2-3 and D, This 15
means maximum frequency S1 number of pulses S2 acceleration deceleration time S3 and the 16
pulse output device only Y0 and Y1 can be specified important point in here also when the PLSR 17
instruction is executed after maximum frequency S1 total number of pulses numbers S2 18
an acceleration deceleration time S3 are set up pulses output from device D the output starts 19
at the frequency of increasing. 20
This is really really important point. 21
The output starts at the frequency of increasing ,V we will have a ramp like this we will get here 22
we will get a time. 23
these graphs will be shaped according to a S1 divided by ten at a time the time of every 24
frequency is S3 divided by nine in here also we have an example plsr command is used in 25
here M1029 is pulse output completed auxiliary relay M1000 always on contact and in here. 26
Let's take a look once to our example. 27
When the plc energized it reached the maximum frequency in three thousand milliseconds or three seconds 28
and it will stop after 10000 heartz or ten kilohertz pulse is produced at 500 hertz frequency in three 29
seconds. 30
And in three seconds we will reach this value. 31
And after three seconds we will get this pulse step and this frequency from Y0 32
And that moment our M1029 auxiliary relay bit will be high. 33
So this contact will be off that moment if sensor is activated or X0 is activated by somebody else 34
or something else as physical input M1029 will be resetted in here. 35
And again this flow will be started and our PLSR command is going to be instructed as in 36
three seconds it will produce again 10000 heartz pulse step at 500 heartz frequency. 37
That's all we can produce. 38
Run pulses with the acceleration and deceleration time with the PLSR/DPLSR command. 39
So I am finished in this video. 40
See you in the next video.
