(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 conveyor axis and rotary knife axis.
When the position of the conveyor axis (main axis current value) is "0", set the position of
the rotary knife axis (feed current value) to "0".
Since the position at power-on is "0", the home position return of the conveyor axis is not
required.
Perform the home position return on the rotary knife axis at the point where the blade of the
cutter becomes the top.
Adjust the conveyor axis and rotary knife axis so that the 0 position of both axes is located at
the center of the sheet length.
3. Selecting cam data Select the cam data to be executed with CI0 to CI3 (Cam No. selection 0 to 3). The user can
use [Cam control data No. 49 - Cam No.] to select the cam data. (Note 1)
4. Servo-on Switch on SON (Servo-on).
5. Switching cam control Switch on CAMC (Cam control command) to switch the control to the cam control. (Note 2)
6. Starting the conveyor axis Check that CAMS (During cam control) is on and start the conveyor axis. (Note 2)
The rotary knife axis is driven in synchronization with the conveyor axis.
Note 1. Use Cam number setting (2D80h) to select a cam No. via the Modbus RTU communication.
2. Use C_CAMC (Control input (bit 5 of 2D02h)) to input a cam control command via the Modbus RTU communication. The
output status during cam control can be read with S_CAMS (Control output (bit 5 of 2D12h)).
