Manufacturing Lot
Number
A310 and
A311
The manufacturing lot number is stored in 5 digits hexadecimal. X,
Y, and Z in the lot number are converted to 10, 11, and 12,
respectively.
Examples:
Lot number 23805
A310 = 0823, A311 = 0005
Lot number 15X05
A310 =1015, A311 = 0005

Error Flag
A751.12
ON when the DM Initial Values Transfer Password (A752) is
incorrect or when the DM Initial values area was not specified
when starting to transfer DM initial values from the DM Area to
the DM initial value area in flash memory.

Save Start Bit
A751.15
Turn ON this bit to start transferring DM initial values. This bit is
valid only when a correct password is stored in A752 and the DM
Area Initial Value Area is specified (i.e., when A753.00 is ON).
The system will turn this bit OFF automatically when the transfer
has been completed.

DM Initial Values
Transfer Password
A752
Set the passwords here to transfer DM initial values between the
DM area and the DM initial value area in flash memory. The
transfer will not be started unless the correct password is set.
The transfer is started when A751.15 is turned ON.
The password will be cleared by the system when the transfer
has been completed.
