Proportional factor of
slave reception
The A90 series inverter supports the master-slave communication function. That is,
one inverter works as the host and others as slaves. The slaves work according to the
command sent by the host, so that these inverters can work synchronously.
The inverter used as the host is set as follows:
F10.05=1: enable the master-slave communication function;
F10.06=1 or 2: select the current inverter as the host (only one inverter can be set
as the host in a network);
F10.07: select the variable to be synchronized, such as the output current (set
F10.07=5).
The inverter is used as the slave is set as follows:
F10.05=1: enable the master-slave communication function;
F10.06=0: select the current inverter as the slave;
Select one setting as the communication setting. If F09.00=6 is set and the process
PID is set separately (F00.05=10, F00.06=1), the slave inverter will be set to the host
output current for PID adjustment.
You can set the receiving proportional coefficient (F10.08) to determine how the slave
inverter receives data. If F10.08=0.80 is set, the final application data is “Recv (received
data) * 0.80 (F10.08)”.

0-10: default operation (for
commissioning)
11: writing not triggered
(available after commissioning)
For the application “PLC controller/HMI + inverter”, you can set F10.56=11 after
debugging. Then all write data of PLC communication will not be stored, which can avoid
damage to the memory.
If you need parameter settings and power-down storage, set F10.56=0 first.
