0013-001FH Reserved
Note 1: write "0" in the reserved BIT.
Note 2: when the communication frequency command is > the largest frequency, the abnormality code 21H
"Beyond the Upper & Lower Limit" will be reported and the operation frequency will be reserved unchanged.
Note 3: addresses of 000DH~0011H and 0013H~001FH are reserved in the general frequency inverter.
Note 4: when the above reserved register addresses are read, address error will be fed back.

00FFH Input Command
Notes:
For the data writing command 06 and 10, only the data are written into RAM for operation and are effective for
this operation. After the inverter is powered off and restarted, the data written last time will become ineffective.
If the data written by communication has to be effective after the inverter is powered off and restarted, the data
should be written and saved in EEPROM. Function 10 can be used to write the parameters of MODBUS address
to be saved into 0x00F.
By writing the MODBUS address corresponding to the parameters to be saved into 0x00FFH, the parameter data
in RAM will be written and saved in EEPROM. As the maximum writing times of EEPROM is 100,000, the
input command had better not be used frequently. The command is similar to ENTER in the keypad, by pressing
which the set parameters will be written into EEPROM. The record code 00FFH is special for writing. When the
record is read, record code errors may happen (abnormality code 02H).
