CHV180 series frequency inverter special for elevator Detailed function description
.74.
to be 0 (that is the broadcast communication address), all slaves on the MODBUS bus
will receive the frame, but the slaves will not make any response. Note that the slave
address should not be set to be 0.
The local communication address is a unique address in the communication network.
This is the basis for point-to-point communications between the upper computer and
the inverter.

This parameter is used to set the data transmission rate between the upper computer
and the inverter.
Note: The baud rate setting of the upper computer should be the same as that of
the inverter. Otherwise, communications cannot be implemented. The higher the
baud rate, the faster the communication speed is.
