2.2 Multi-Project Function

2.2.2 Range of Usable Project

The range of usable project differs depending on the models as follows.
M800V Series 1 to 6 projects (3 projects and more will be additional specifications.)
M80V Type A, M80VW 1 to 3 projects
M80V Type B 1 to 2 projects

2.2.3 Multi-Project Function Usage Steps

To enable the multi-project function, follow the steps below and set the multi-project parameter and the device number
parameter.
 Multi-project function change steps
When the sequence program is already stored in CNC, follow the steps below and carry out the setting.
Development procedure
(1) Back up the sequence program
(2) Format the temporary storage area (RAM in CNC)
(3) Clear the data in built-in ROM (ROM in CNC)
(Clear the data by writing the empty temporary storage area into
the built-in ROM.)
(4) Set the multi-project parameter and the device No. parameter
(5) Change the device points set in the PC parameter of the backed
up sequence program
(6) Write back the backed up sequence program to the CNC
 New setting steps of multi-project function
When the sequence program has not yet stored in CNC, follow the steps below and carry out the new setting.
Development procedure
(1) Set multi-project parameter
(2) Set device No. parameter
(3) Restart the CNC
