ASDA-A2 Chapter 7 Motion Control
7-32 Revision February, 2017
Gear＃1, the description is as follows:
Function
Set the relativity of master axis and E-cam axis.
E.g. The master axis operates one cycle; the E-cam axis is no
need to operate one cycle.
Description
E-cam axis is a virtual axis.
The E-cam axis operates one cycle (360 degrees) means the
cam operates one cycle and the slave axis operates one
cycle.
The pulse number is the unit of moving distance of the master
axis. Its resolution is determined by the source.
Setting Method
P5-83: M
P5-84: P
If the pulse number of master axis is P, the E-cam axis
operates M cycle.
Then, the setting of gear ratio is P5-83＝M, P5-84＝P
Cam, the description is as follows:
Function
Set the relation between E-cam axis and slave axis and define it in
the E-cam table.
E-cam axis operates one cycle and the slave axis operates one
cycle.
Data Storage
Address of E-
Cam table
Data array, the start address is set by P5-81
Data Format
32-bit (It has positive and negative, user unit: PUU)
E-Cam Curve
Scaling
P5-19
0 ~ +/- 32.700
It is used to magnify (minify) the E-cam shape.
It equals to the value of data multiplies P5-19.
Switch the symbol, ＋／－ will change the operation direction of
slave axis.
If P5-19 is set to０, the E-cam command will not be outputted. (The
setting will be 0 for good).
Data Size
It is divided into N parts via P5-82 (> = 5) and does not exceed the
limit of data array. It means 360 degrees a cycle of E-cam are
divided into N areas. Each area is (360/N) degrees.
Data Content
The position data of slave axis is saved in E-cam table. (User unit:
PUU).
If E-cam is divided into N areas, the position of each area must be
included in the table. It must set N＋1 points in total. It is because
the position of the first point (0 degree) and the final point (360
degree) might not be the same.
