Table 5-13:ROM operation/high-speed RAM operation function image
DRAM is used as execution memory during ROM operation/high-speed RAM operation; it can perform lan-
guage processing at a maximum speed of about 1.2 times faster than that of SRAM memory used for nor-
mal RAM operation. (The speed varies depending on the contents of each program.)
Note that the operations of the robot, such as program execution and step operation, can be performed sim-
ilar to RAM operations (when starting in the RAM mode); however, there are restrictions on some opera-
tions. Please refer to the following precautions.
