7.10.2 Read and Write State Parameters
The state parameters include the monitoring parameters in group U (U0 to UF), the drive fault information and the drive running
state.
ƕ The highest 8 bits in the communication of parameters in U0 to UF is 70 to 7F, while lowest eight bits indicate the hexadecimal
number converted from the SN in the function code group. For example, the communication address of U0-11 is 700BH.
ƕ The communication address of the drive fault information is 8000H. You can obtain the current fault codes by using the host
computer to read the address.

Here takes the CANopen protocol as an example to describe the communication process of the host computer to read the drive
running state.

range: 1 to 63), and the drive running state is 1: forward run.
The format of the message sent by the master is as follows:
Message ID (Hex) RTR Data (Hex)
0x605 0 40 30 00 00 00 00 00 00
0x605 = 0x600 + 0x05 (Node-ID DIP setting)
The format of the response message returned by the slave is as follows:
Message ID (Hex) RTR Data (Hex)
0x585 0 40 30 00 00 00 00 00 00
0x585 = 0x580 + 0x05 (Node-ID DIP setting)
The sending message and the response message are described as follows:

Note
To read the monitoring parameters, the drive fault information and other drive running state via the CANopen protocol,
refer to the sending message format and response message format in the following tables to organize the message.
