10. COMMUNICATION FUNCTION (MITSUBISHI ELECTRIC GENERAL-PURPOSE AC SERVO PROTOCOL)
10 - 28
(2) Writing data
CAUTION
If setting values need to be changed with a high frequency (i.e. once or more per
hour), write the setting values to the RAM, not to the EEP-ROM. The EEP-ROM
has a limitation in the number of write times, and exceeding this limitation causes
the servo amplifier to malfunction. Note that the number of write times to the EEP-
ROM is limited to approximately 100,000.
(a) Position data
Writes position data of point tables.
Transmits the command [C] [0] + the data No. [0] [1] to [1] [F] corresponding to the point tables to
write. Refer to section 10.1.1.
Command Data No. Data
[C] [0] [0] [1] to [1] [F] Refer to the following:
Data is transferred
in hexadecimal.
Writing mode
0: Writing to EEP-ROM/RAM
1: Writing to RAM
Decimal point position
0: No decimal point
1: First least significant digit (not used normally)
2: Second least significant digit
3: Third least significant digit
4: Forth least significant digit
5: Fifth least significant digit
6: Sixth least significant digit
Select the same decimal point position
as the set feed length multiplication
(STM) in [Pr. PT03].
If a different decimal point position is
set, slave stations will not receive data.
When changing the position data frequently using communication, set "1" to the write mode to
change only the RAM data in the servo amplifier.
When changing data once or more within an hour, do not write it to the EEP-ROM.
