Hello in this video.
1

2
00:00:23,130 --> 00:00:26,430
We are going to learn high speed counters and pulse types introduction
2

3
00:00:26,520 --> 00:00:30,180
This is an introduction briefly.
3

4
00:00:30,480 --> 00:00:37,700
So in here we have a picture incremental rotary encoder example ES5 for Delta.
4

5
00:00:37,950 --> 00:00:47,660
So for this rotary encoder phase A is black cable phase B is white cable phase Z the orange cable.
5

6
00:00:48,120 --> 00:00:57,260
+ power supply is brown and ground is blue in here clockwise sequence and counterclockwise sequence
6

7
00:00:57,360 --> 00:00:58,800
for these encoder.
7

8
00:00:59,250 --> 00:01:10,620
So what happens if the encoders turns clockwise direction so phase A is always goes 90 degree forward
8

9
00:01:10,710 --> 00:01:22,210
or 90 degree phase ahead from phase b and this is clockwise direction if you turn counterclockwise direction
9

10
00:01:22,420 --> 00:01:30,770
opposite direction that moment phase B goes 90 degrees apart or ahead from phase A.
10

11
00:01:31,030 --> 00:01:41,020
This is the phase a and phase B diagram so we can say that each time for the encoders 90 degree is between
11

12
00:01:41,360 --> 00:01:50,500
if we go clockwise direction, phase a is a little bit forward I mean a little bit 90 degree
12

13
00:01:50,590 --> 00:02:00,280
forward if we go to counterclockwise phase B is forward then phase a and pulse types you can see
13

14
00:02:00,520 --> 00:02:03,590
if you are using pulse + direction.
14

15
00:02:03,640 --> 00:02:10,910
So in here you can see steps and the pulses and the direction is one side for example.
15

16
00:02:10,900 --> 00:02:21,250
Now it is going to clockwise and another side is counterclockwise and steps means pulses will be always
16

17
00:02:21,460 --> 00:02:26,020
similar not goes to another direction.
17

18
00:02:26,020 --> 00:02:33,730
This is all , and clockwise and the counterclockwise mode  you will see clockwise pulses in here
18

19
00:02:33,910 --> 00:02:42,640
but counterclockwise will be zero because just one side we can turn and clockwise is finished and we
19

20
00:02:42,640 --> 00:02:47,120
can start to another direction pulses like this.
20

21
00:02:47,260 --> 00:02:57,390
And in here quadrate outputs a phase and b phase, a phase is if we are turning clockwise direction will
21

22
00:02:57,390 --> 00:03:03,400
be 90 degree forward and if we are turning counterclockwise.
22

23
00:03:03,470 --> 00:03:12,590
And that moment for example B will be forward then a how many degree 90 degrees.
23

24
00:03:12,600 --> 00:03:19,710
It is similar and the pulse output mode settings D1220 and 21 and 29
24

25
00:03:19,710 --> 00:03:26,700
and 30 in D1224 phase  of the first group pulse output for Channel0
25

26
00:03:26,700 --> 00:03:33,480
Y0  and Y1, phase of the second group also good for Channel1.
26

27
00:03:33,490 --> 00:03:34,910
Y2, Y3
27

28
00:03:35,250 --> 00:03:45,260
So if we want to use third group pulse output for Channel 2 Y4 - Y5 is available just in eh2/sv/eh3/sv2
28

29
00:03:45,270 --> 00:03:53,940
delta plc models and the first and the fourth group pulse out also for Channel3
29

30
00:03:53,940 --> 00:04:03,420
Y6-Y7 available in eh2/sv/eh3/sv2 Delta plc  models,  this is the pulse types
30

31
00:04:03,780 --> 00:04:07,380
and this is the just a scheme to show you.
31

32
00:04:07,380 --> 00:04:16,110
Show us to learn how pulse and  direction and how A phase and  B phase  works or how counter clockwise
32

33
00:04:16,110 --> 00:04:24,660
or clockwise directions are works this is just the grubs This is just a theoretically information and
33

34
00:04:24,900 --> 00:04:27,300
for this video your I am finished here.
34

35
00:04:27,300 --> 00:04:28,530
See you in the next video.
