if M is 116%, protection will be applied when
motor overloads for 1h; if M is 200%, protection
will be applied when motor overloads for 60s; if M
is no less than 400%, protection will be applied
immediately.

communication
address
Setting range: 1–247
When the master is writing frames, and the slave
communication address is set to 0, it is the
broadcast communication address, and all the
slaves on the Modbus bus will accept this frame,
but the slave never responds.
Local communication address is unique in the
communication network, which is the basis for
point-to-point communication between the upper
computer and the inverter.
Note: The slave address cannot be set to 0.
