(2) Parameter write
POINT
The number of parameter write times is restricted to 1,000,000 times.
Write the parameter setting.
Write the value within the setting range. Refer to Section 5.1 for the setting range.
Transmit command [8][4], the data No., and the set data.
The data No. is expressed in hexadecimal. The decimal equivalent of the data No. value corresponds to
the parameter number.
When the data to be written is handled as decimal, the decimal point position must be specified. If it
is not specified, data cannot be written. When the data is handled as hexadecimal, specify 0 as the
decimal point position.
Write the data after making sure that it is within the upper/lower limit value range given in Section
5.1.2. Read the parameter data to be written, confirm the decimal point position, and create
transmission data to prevent error occurrence. On completion of write, read the same parameter
data to verify that data has been written correctly.
Command Data No. Set data
[8][4] [0][0] to
[5][4]
See below.
Data is transferred in hexadecimal.
Decimal point position
0: No decimal point
1: Lower first digit
2: Lower second digit
3: Lower third digit
4: Lower forth digit
5: Lower fifth digit
Write mode
0: Write to EEP-ROM
3: Write to RAM
When using communication to change parameter values frequently,
set "3" here and change data on RAM in the servo amplifier.
Frequent change to EEP-ROM data may cause the permissible write
times (1 million times) of EEP-ROM to be exceeded, leading to a failure.
