2）Inverter status: Read the inverter status, see 27 groups of function codes.
Decimal address: 27 × 256 + 10 = 6922.
Example 2: Function code 14.01 (digital setting of torque reference), when
no EEPROM is stored, its
The hexadecimal address is: 0x0E01 (0x0E = 14, 0x01 = 1),
The decimal address is: 14 × 256 + 1 = 3585.
If you want to save the content written in communication to EEPROM after
power off, then
The hexadecimal address is 0x8E01 (0x0E01 plus 0x8000),
The decimal address is 36353 (3585 plus 32768).
Note: The addresses calculated in hexadecimal or decimal are the same,
and users can choose a familiar calculation method.

External fault setting
DO status setting. When the DO function (please refer to P07.01 ~ P07.10)
is set to 0 (no function), its status comes from the setting of the
communication dedicated register, and the corresponding bit of 1 means it
is valid. The bits of this register are defined as follows:
