14 ROM OPERATION FUNCTION
(4) Operation at the
"Mode operated by ROM"
Operation at the "Mode operated by ROM" is shown below.
Mode operated by ROM start
After that, it cannot be operated because of
stop status.
Retry the operation for "ROM writing"
"Mode operated by ROM" after confirm the
contents for programs and parameters of
internal SRAM.
Read the system setting data, each
parameter for servo control, servo
program, mechanical system program
(SV22 only) and cam data (SV22 only) in
the internal FLASH ROM to the internal
SRAM .
Is the registration
code of internal FLASH
ROM normal ?
YES
NO
Motion CPU WDT error [302] occurs, and
"ERROR LED" turns ON.
Wait the restart of Multiple
CPU system.
Normal operation start
After that, it is same operation at the
RAM operation.
(Programs and parameters
written in the internal FLASH
ROM are normal.)
(Programs and parameters written in the
internal FLASH ROM are abnormal.)
or
(When the additional parameters (for ROM
operation function) are wrote in the internal
FLASH ROM and a version of operating system
software does not correspond to the ROM
operation function.)
POINT
If the ROM operation of a data written in the internal FLASH ROM is executed in
the combination of the Motion CPU module for additional parameter (ROM
operation function) and programming software by the operating system software
not for additional parameter (ROM operation function), a Motion CPU WDT error
(error code: 302) will occur and the ROM operation cannot executed.
In this case, use the operating system software for additional parameter (ROM
operation function). (Refer to Section 1.3.4.)
