Group U0: Fault logging parameters
The inverter provides 3 groups of fault record parameters, all of which are read-only parame-
ters, which are convenient for users to view and troubleshoot inverter fault-related informatio-
n. For details, please refer to Appendix B Function Code Parameter Table or Chapter VII
<<Fault Diagnosis Level Countermeasures>>.
Group U1: Application Monitoring Parameters
The U1 parameter group is used to monitor the relevant variable information when the inver-
ter is running. The customer can view it through the panel to facilitate on-site debugging, or
read the parameter group value through communication for monitoring by the host computer.
The communication address is 0x71xx.
Among them, U1-00 ～ U1-31 are the running and stop monitoring parameters defined in P7-
29 and P7-30.

Displays the current DI terminal input status value. After conversion into binary data, each bit
corresponds to a DI input signal, 1 indicates that the input is a high-level signal, and 0 indica-
tes that the input is a low-level signal. The corresponding relationship between each bit and
the input terminal is as follows:
