■Stroke ratio data format
■Coordinate data format
For coordinate data format, when writing is not completed in one attempt, divide the writing over several
attempts.
• During the execution of the CAMWR instruction, another CAMWR instruction, or CAMMK instruction cannot be processed.
During the execution of the CAMWR instruction, the "Cam data operation flag (SM505)" turns on. Therefore, create an
interlock. When the CAMWR instruction, or CAMMK instruction is executed while the "Cam data operation flag (SM505)" is
on, an error occurs.
The CAMWR instruction can be executed during the synchronous control. Note that the contents of the cam
data in operation are changed depending on the instruction execution timing.
