Note:
The inverter fault information read from the fault address is consistent with the fault record code in Table 7-
1 in Chapter 7.
If the operation request fails, the response is the error code and the exception code. The address is
0x8001 the meaning of the exception code is as follows:
Abnormal code Abnormal code meaning Abnormal code Abnormal code meaning
0x0001 wrong password 0x0005 Illegal data, operating data is
not within the upper and lower
limits
0x0002 Read and write command
error
0x0006 Parameter read-only, does not
allow changes
0x0003 CRC check error 0x0007 Read and write failed, factory
parameters are not allowed to
operate
0x0004 Illegal address, operation
address error
0x0008 Parameter does not allow
changes
CRC check
Taking into account the need to improve speed, CRC-16 is usually achieved using the form,
