by ROM
(b) Operation mode overview
• " . " remains flashing in the first digit of 7-segment LED.
• It operates based on the user programs and parameters stored in the SRAM
built-in Motion CPU module.
• The user programs and parameters for the ROM operation can be written to
the FLASH ROM built-in Motion CPU module.
• " . " remains flashing in the first digit and steady " . " display in the second
digit of 7-segment LED.
• Operation starts after the user programs and parameters stored in the FLASH
ROM built-in Motion CPU module are read to the SRAM built-in Motion CPU
module at power supply on or reset of the Multiple CPU system.
If the ROM writing is not executed, even if the user programs and parameters
are changed using the MT Developer2 during mode operated by ROM,
operation starts with the contents of the FLASH ROM built-in Motion CPU
module at next power supply on or reset.
Also, If the ROM writing is not executed, even if the auto tuning data are
reflected on the servo parameter of Motion CPU by operation in the auto-
tuning setting, operation starts with the contents of the FLASH ROM built-in
Motion CPU module at next power supply on or reset.
POINT
(1) Be sure to turn OFF the Multiple system's power supply before the rotary
switch setting change.
(2) It is recommended to shift to the mode operated by ROM after the programs
and parameters are fixed. The erasing of the programs and parameters can be
avoided even if the battery decrease. (The ROM writing cannot be executed
for the current position of the servo motor in the absolute position system,
home position and latch device. Back up them beforehand using
MT Developer2.)
