Number of automatic fault reset: when the inverter selects automatic fault reset, it is
used to set the number of times of automatic fault reset. When the times of the inverter
continuous reset exceed this value, the inverter fault standby, the manual intervention is
required.
Automatic fault reset interval setting: choose interval between fault occurrence and
automatic reset.

This parameter is used to set the data transfer rate between the host computer and the
inverter. Note: the baud rate must be set to the same for the host computer and the
inverter, otherwise communication can not be achieved. The larger baud rate, the faster
communication speed.
