1) Inverter No. (1 byte)			: Specify an inverter number between 0 and 247 (00H to F7H).
			Command processing will be executed only broadcast communication “0” and with
			those inverters that match set inverter numbers.					Data will not be returned if “0”

(broadcast communication) and inverter numbers do not match.

2)

Command (1 byte)

: Set the write command (06H fixed).

3)

Communication No. (2 bytes) : Set in the order of high to low numbers.

4)

Write data (2 bytes)

: Set in the order of high to low write data.

5)

CRC (2 bytes)

: Set generation results of CRC in the order of low to high numbers.

For the method to

generate CRC, see “5.2 CRC Generation.” Note that the setting sequence is rever-

sal to that of others.

Note

▼The EEPROM life is 10,000 operations.

Do not write in the same parameter that has an EEPROM more than 10,000 times.
