8.4.3 CAM Operation
CAM axis control synchronizing with the position of main motor.
(1) Characteristics of Control
(a) Replace existing mechanical work of CAM with software CAM operation
Servo
motor
CAM data
(b) You may write max. 9 CAM data blocks and apply it to each axis.
(c) Each block consists of 2048 CAM data.
(d) Auxiliary data of CAM command
Auxiliary data used in CAM command is as follows.
Item Setting value Description
Main Axis
1(Axis1) ~ 4(Axis4),
9(Encoder)
Set the main axis of CAM operation
CAM block 1(no.1) ~ 8(no.8) Set CAM block no.
Main axis
offset
-2147483648 ~
2147483647
Set the position of main-axis position as offset value if main-axis
reaches this position, the sub-axis starts CAM operation.
Encoder can not be used as main axis.
You may set different CAM block no. for each axis. In addition, it is possible to execute CAM operation with the same CAM
block. In order to use user CAM operation, you have to set up CAM block number as 8.
(e) You can make sub-axis start the CAM operation at the specified position of main-axis by setting the “Main axis offset”.
Main axis offset setting is available at “Offset specified CAM start command (XCAMO, XPM_CAMO).
(f) Create CAM data by setting CAM parameter on XG-PM to use CAM.
(g) After main axis is operated, input the calculated value per CAM block setting and point unit based on the current value per
rotation of main axis. For the detail description, refer to “(3) Principle of CAM operation”.
(h) If CAM operation is executed on sub axis, it become ‘operating status’ and keep executing CAM operation with CAM data
according to the position of main axis until stop command.
