Setting example of axis 2
Item Setting
Setting
value
Operation mode selection ([Pr.
PA01])
Select "Point table method". "1006"
Simple cam function setting ([Pr.
PT35])
Enable the simple cam function. "_ 1 _ _"
Device setting Assign CAMC (Cam control command input), CAMS (Output in cam control), and
CI0 to CI3 (Cam No. selection 0 to 3) with I/O setting parameters ([Pr. PD_ _ ]).
Refer to
section
7.2.4.
Command unit ([Pr. PT01]) Set "mm" as the unit of position data. "_ 0 _ _"
Cam axis one cycle length ([Cam
control data No. 30])
Set the travel distance of the axis 1 (horizontal axis). 600.000
Cam stroke amount ([Cam control
data No. 51])
Set the travel distance of the axis 2 (vertical axis). 200.000
Main shaft input axis selection ([Cam
control data No. 30])
Select "Servo input axis". 1
Point table No. 1 Set the same target position as that of the point table No. 1 of the axis 1.
Set the same servo motor speed and acceleration/deceleration time constants for
the point table No. 1 of the axis 1.
600.000
Point table No. 2 Set the same target position as that of the point table No. 2 of the axis 1.
Set the same servo motor speed and acceleration/deceleration time constants for
the point table No. 2 of the axis 1.
0.000
Cam data Create a cam pattern according to the axis 1 position. (Refer to Fig. 6.6.)
(b) Operation
The following table shows an example of the procedure before operation.
Step Setting and operation
1. Data setting Refer to the setting example on the previous page and set the data.
2. Initial position adjustment Adjust the synchronous positions of the axis 1 and 2.
In this example, when the position of the axis 1 (command position) is "0", adjust the
synchronous position so that the position of the axis 2 (feed current value) becomes "0".
3. Point table selection Select the point table No. 1 for both axis 1 and 2.
4. Selecting cam data Select the cam data to be executed with CI0 to CI3 (Cam No. selection 0 to 3) of the axis 2.
The user can use [Cam control data No. 49 - Cam No.] to select the cam data.
5. Servo-on Switch on SON (Servo-on) for both axis 1 and 2.
6. Switching cam control Switch on CAMC (Cam control command) of the axis 2 to switch the control to the cam
control.
7. Starting the simultaneous start
function
Check CAMS (During cam control) of the axis 2 is on and start the operations of the axis 1
and 2 simultaneously. The axis 2 is driven in synchronization with the axis 1.
