*Procedure 4: Starting
Start the program 1 and program 2 operation by starting from the operation panel.
4.2.7 Program capacity
There are 3 types of areas that handle robot programs; save, edit and execution. Refer to
3Capacity of each program area"
for the capacity of each area.
(1) Program save area
This area is used to save programs. Under normal circumstances, it is possible to save 220 Kbytes of pro-
gram code in total. The capacity of the program save area can be increased to 2 Mbytes, if it is insufficient,
by mounting expansion memory.
(2) Program edit area
This area is used when editing programs and checking the operation in step execution. The program edit
area has a capacity of 179 Kbytes, which is the maximum size of one program. The capacity of the program
edit area cannot be increased by mounting expansion memory.
(3) Program execution area
The program execution area is used when operating a program automatically. The capacity of the program
execution area is 184 Kbytes. The total capacity of programs loaded into the execution area at the same
time via user base programs, for multitasking purposes, or by XRun and CallP instructions, must be 184
Kbytes or less. The capacity of the program execution area cannot be increased by mounting expansion
memory.
Table 4-3:Capacity of each program area
The capacity of each program can be checked with the teaching pendant and the Program Manager window
of the Personal Computer Support Software.
