Embedded macro program (macro program)
The macro programs made by MTB are stored. When the embedded macro program
is edited, an operator edits the program on DRAM and the edited program is stored
in FROM by the softkey operation. When the embedded macro program is edited, it
is necessary to store the program in FROM because the program on DRAM is
deleted when the power supply is turned on again.
Tape storage memory program (user program)
The CNC programs made by a user (operator). Even if the power supply is turned on
again, the programs are not deleted.
(1) Edit of embedded macro program
The macro programs on DRAM can be edited on the program screen. And
parameter setting can prohibit the edit of the embedded macro program. The edit
operation is the same as the edit of the normal user program. Program input/output
operation is also the same as that of the normal user program. The embedded
macro programs and the user programs are distinguished according to the program
(2) Programs writing from DRAM to FROM and programs reading from FROM to DRAM
The embedded macro programs on DRAM can be written to FROM by the softkey
operation. At the same time, the program administrative information and the
embedded macro parameters are forwarded from SRAM to DRAM, and written from
DRAM to FROM. When the power supply is turned on, reading from FROM to DRAM
is automatically done. At this time, this function is checked whether the program
administrative information of SRAM is correct and the parameters for embedded
macro are rewritten by FROM data. The program reading from FROM to DRAM is
also done by the softkey operation. By this operation, the current DRAM area is
overwritten by the data in FROM area.
(3) Input to FROM and output from FROM
The embedded macro program file stored in FROM can be input and output by
BOOT SYSTEM with a memory card.
