Create Cam Data

Memory operation of cam data

Cam data is arranged in the following 2 areas.
Area Storage item
Cam storage area Cam storage data
(Standard ROM/ (Cam file)
SD memory card)
Cam open area Cam open data
Previously written cam data can be used after turning the Multiple CPU system power supply OFF by writing data in the cam
file. Cam data should be written in the cam file for normal use.
It is possible to write the cam data to the cam open area via the device specified by Motion SFC program when fine adjusting
cam data during cam control etc.
The cam file must also be updated as appropriate because the contents of the cam file are transmitted to the cam open area
when turning the Multiple CPU system power supply ON again.
When the cam file is updated, the contents of the cam open area can be updated using "File transmission request (SD820)".

*1 The operations from MT Developer2 are for the cam file.
*2 Cam data is written to the cam open area at Multiple CPU system power supply ON, or by "File transmission request(SD820)".
*3 The contents of the cam open area are cleared by turning the Multiple CPU system power supply OFF and ON again, or by reset.
The cam files in the cam storage area can also be sent to the cam open area by *2.
Details
Data is written by the following operations.
• Write with MT Developer2
• When specifying a cam file for writing data and executing
the CAMWR/CAMMK instruction of Motion SFC program.
• Cam data is transmitted from the cam file, when turning the
Multiple CPU system power supply ON.
• Writing to the cam open area is also possible using the
CAMWR/CAMMK instruction or "File transmission request
(SD820)".

Remark
Data is preserved even when turning the Multiple
CPU system power supply OFF.
• Data is lost when turning OFF or resetting the
Multiple CPU system power supply.
• The cam data that is used in cam control is
stored.
