6. Description of Parameters
6.10.2 Read and Write State Parameters
State parameters include monitoring parameters in group U (U0 to UF), drive fault information
and drive running status.

Here takes CANopen protocol as an example to describe communication process of host
computer to read drive running status.
First set F0-28 = 1 to select CANopen protocol. Suppose that DIP setting of Node-ID of the AC
drive is 0x05 (modifiable, range: 1 to 63), and drive running status is 1: forward run.
The format of message sent by the master is as follows:
0x605 = 0x600 + 0x05 (Node-ID DIP setting)
Format of response message returned by the slave is as follows:
6
0x585 = 0x580 + 0x05 (Node-ID DIP setting)
Sending message and response message are described as follows:
- 204 -
The highest 8 bits in communication of parameters in U0 to UF is 70 to 7F, while lowest
eight bits indicate the hexadecimal number converted from SN in function code group. For
example, communication address of U0-11 is 700BH.
Communication address of the drive fault information is 8000H. You can obtain current fault
codes by using host computer to read the address.
Communication address of drive running status is 3000H. Word in the read information is
defined as 1: forward run, 2: reverse run, 3: stop.
