6.1 Schedule of Function Parameters 6.1 Schedule of Function Parameters
Group F8 Communication Parameters
F8.00 Local address Setting range: 0~31 Default value: 1
This parameter is used to identify the local inverter's address which is unique when
an inverter communicates with other inverters or upper machines through COM port.
If this parameter is set to "0", the local inverter under linking control will act as the
main station, which decides the operation of other inverters connected to it.
If this parameter is not set to "0", the local inverter will act as a secondary receiving
commands and data from the upper machine or the inverter acting as the role of main
station. The inverter receives only commands and data from the upper machine or
the main station in accord with marked address.
F8.01 Communication config. Setting range: -000~ -125 Default value: - 013
This parameter defines the baud rate of COM. The data format adopted in the
protocol shall be in accord, which is the premise for normal communication.
LED units digit: Baud rate setting
0: 1200BPS
1: 2400BPS
2: 4800BPS
3: 9600BPS
4: 19200BPS
5: 38400BPS
LED tens digit: Data format
0: No parity
1: Even parity
2: Odd parity
LED hundreds digit: Communication failure action selection
0: Shutdown
1: Remain the current state
LED thousands digit: Remain
All the data formats select 1-bit as their starting digit, 8-bit as their data digit and 1-
bit as their stop digit.
F8.02 COM over time checkout time Setting range: 0.0~ 100.0s Default value: 10.0s
If correct data signal is not received by the local machine within/exceeding the
interval defined by this parameter, then communication error will be judged by the
local machine. Hence, the inverter will decide whether to stop running or maintain the
current state according to the treatment method of communication failure.
F8.03 Local machine response delay time Setting range: 0~1000ms Default value: 5ms
This parameter defines the delay time that the local machine delivers the response
data frames to the upper machine after the local machine accepts correctly the
information codes from the upper machine.
F8.04 Linking proportion setting Setting range: 0.01~10.00 Default value: 1.00
If local inverter is set to be controlled by master inverter and the setting frequency
of local machine is given by the master inverter, then this parameter is used to set
weight coefficient of frequency instruction received by the local inverter which
acts as a secondary through RS485/232 port. The actual setting frequency of local
inverter is equivalent to the product of local parameter value and the frequency
setting instruction value received through RS485/232 port.
