Setting example of axis 2
Item
Operation mode selection ([Pr.
PA01])
Simple cam function setting ([Pr.
PT35])
Device setting
Command unit ([Pr. PT01])
Cam axis one cycle length ([Cam
control data No. 30])
Cam stroke amount ([Cam control
data No. 51])
Main shaft input axis selection ([Cam
control data No. 30])
Point table No. 1
Point table No. 2
Cam data
(b) Operation
The following table shows an example of the procedure before operation.
Step
1. Data setting
2. Initial position adjustment
3. Point table selection
4. Selecting cam data
5. Servo-on
6. Switching cam control
7. Starting the simultaneous start
function
Select "Point table method".
Enable the simple cam function.
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_ _ ]).
Set "mm" as the unit of position data.
Set the travel distance of the axis 1 (horizontal axis).
Set the travel distance of the axis 2 (vertical axis).
Select "Servo input axis".
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.
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.
Create a cam pattern according to the axis 1 position. (Refer to Fig. 6.6.)
Refer to the setting example on the previous page and set the data.
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".
Select the point table No. 1 for both axis 1 and 2.
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.
Switch on SON (Servo-on) for both axis 1 and 2.
Switch on CAMC (Cam control command) of the axis 2 to switch the control to the cam
control.
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.
