PLC | Motor gear belt, electronic gear ratio of the algorithm

Electronic gear ratio is defined: It is hoped a number of pulses = distance moving parts (Input 1 pulse = pulse number of the motor will go (travel))
Therefore, the belt teeth, pitch not the focus, Do not also counted out. (Circle if the actual number of teeth of course, is the best.)

Key: 1 pulse to go much distance.
1 gear ratio of 1:1 in the case. 2. We must know how much input pulse (# 1), the motor will run a lap. (Motor size) 3 orders to walk around the motor. (Need to confirm whether there is a walk around the motor.) 4 test objects moving distance (# 2)
If you want a pulse to go 1um Electronic gear ratio denominator = # 2 Molecular electronic gear ratio = # 1
If you want a pulse to go 0.5um = (1um / 2) Electronic gear ratio denominator = # 2 Molecular electronic gear ratio = # 1 / 2
Example: Circle = 10000 pulse motor, screw pitch = 5mm
1 set gear ratio = 1:1 2 pulse input 1000 (# 1) 3 Confirm the motor with a turn 4 objects move 5mm (# 2)
Results: To set a pulse = 1um
Electronic gear ratio denominator = 5000um = 5mm Than the molecular electronic wheel wheel = 10000
Test:
When the pulse input 10 000 10000 (input pulse number) x [10000 (molecule) / 5000 (denominator)] == 20000 pulse (motor will actually walk)
Motor will actually get to go 20000 pulse = 2 laps = 2x5mm = 10mm = 10000um # #

PLC|馬達齒輪皮帶、電子齒輪比的算法

電子齒比的定義：
就是希望1脈波=工件移動多少距離
(輸入1脈波=馬達會走多少脈波(距離))

所以皮帶的齒數、齒距都不是重點，
不需要也算的出來。
(如果有實際的齒數圓周當然是最好的。)


重點：1脈波走多少距離。

1.在齒輪比1:1的情形下。
2.我們一定知道輸入多少脈波(#1)，馬達會運轉一圈。(馬達規格)
3下命令讓馬達走一圈。(需要確認馬達是否有走一圈。)
4.測試物件移動的距離(#2)

如果想要一脈波走1um
電子齒輪比的分母= #2
電子齒輪比的分子= #1


如果想要一脈波走0.5um=(1um/2)
電子齒輪比的分母= #2
電子齒輪比的分子= #1/2

例：
馬達一圈=10000脈波，螺桿pitch=5mm

1.設定齒輪比=1:1
2.輸入1000脈波(#1)
3.確認馬達有轉一圈
4.物件移動5mm(#2)

結果：
要設定1脈波=1um

電子齒輪比的分母=5000um=5mm
電子輪輪比的分子=10000

實測：

當輸入10000脈波
10000(輸入脈波數)x[10000(分子)/5000(分母)]==20000脈波(馬達實際會走)

得到馬達實際會走20000脈波=2圈=2x5mm=10mm=10000um ##
