F4.1 Local address Setting range
：
0 ~ 30
Set local address when this inverter communication, only valid when this is Master. During
communication process, this machine will only feedback corresponding frame when the data is
matched to this address, and receive order.
RS485 communication address 31 is broadcasting address, and MODBUS communication 0 is
broadcasting address. Regarding broadcasting data, slave performs order, but do not feedback
corresponding data (refer to appendix communication protocol).
F4.2 Local responding delay Setting range
：
0 ~ 1000 ms
It is the waiting time that when local receives right information code from control equip to
sending responding data frame.

F4.4 Communication overtime checkout time Setting range: 0.0 ~ 100.0 S
When it is beyond defined time interval by this parameter, and not receive right data signal, it
judges communication failure. According to [F4.3] set running mode after communication failure,
select stop or continued running.
F4.5 Linkage set proportion Setting range
：
0.1 ~ 10.0
Define master and slave output freq proportion when linkage control.
This parameter unit of master inverter has no action. When RS485 interface achieves linkage
synchronous control, slave running order and master is synchronous. Slave freq order follows
below format:
Slave freq order = Master freq order × Slave [F4.5] set
