HD1-E CANopen instruction manual
- 15 -
Parameter address of HD1 series inverters: The high byte is the number in front of decimal point of the function code while the low byte
is the number behind decimal point; the address should be converted into hexadecimal. Take P10.01 for example, 0x0A for the high bit
of parameter address due to 10 in front of decimal, 0x01 for the low bit of parameter address due to 01 behind decimal point, so the
address of the function code is 0x0A01.

Parameter address of CHV series inverters: The value that the serial number of each function code corresponds to in the appendix of list
of function parameters is the parameter address. It has to be converted into hexadecimal. For example, the serial number of function
code Pd.14 is 1314, the address is 0x522 (1314 for decimal).
The request data made up of two bytes with low Byte4 and high Byte5 indicates modified data. For read command, the request data will
be meaningless.
Note: Data area of PDO1 Rx must have six bytes; otherwise, the communication card will send EMCY.

Instruction
Byte6 and Byte7 are reserved to be 0x00.
The response code has two bytes, Byte0 for low byte, Byte1 for high byte, and its functions are shown in Table20.

Read and write error, refer to Table21 for error code
Response data have four bytes, Byte4 for low byte, Byte7 for high byte. For write command response, the response data will be modified
data while for read command response, the response data will be read data.
The error code has two bytes, Byte2 for low byte, Byte3 for high byte, and it is valid only when the response code equals to 3. Refer to
Table21 for reasons that error code cannot respond PDO1 Rx.

Meaning
00H
No error
01H
Illegal command
The request code does not allow the operation. It is possible that the function
code is only available for a new device but unavailable for this device, or the
slave station deals with the request in error condition.
02H
Illegal data address
The device of slave station does not allow the parameter address on the
request of master station; specially, the combination between register address
and transmitted bytes is invalid.
03H
Illegal value
Received data field includes illegal value indicating the error on remaining
structure of combination request. Note: The value does not mean that there is
a value out of application expectation for the storing data items in register.
04H
Operation failed
Write operation is invalid to parameter setting. For example, the function input
terminal cannot be set repeatedly.
05H
Password error
The password for password check address is different from the password set
by users.
06H
Data frame error
In the information sent by the upper computer, the length of data frame is
incorrect, or the calculations of CRC check in RTU format and lower computer
verification are asynchronous.
07H
Read-only parameters
The parameters modified in write operation for master station are read-only.
08H
Unmodifiable parameters in
running
The parameters modified in write operation for master station are unmodifiable
in running.
09H
Password protection
During master station read or write, if setting user password but not unlocking
according to password, it will report the system is locked.
