PC.04 master−slave mode:
0: SCIA is slave mode and SCIB is slave mode
T: SCIA is master mode and SCIB is slave mode
T: SCIA is slave mode and SCIB is master mode
PC.05 master to slave operation address (set by master), the slave can save the data sent from master
into the P0.05, P8.00 or P8.0T, that is determine by master parameter PC.05:
0: P0.05
T: P8.00
T: P8.0T
The inverter provides two communication ports. SCIA is a port connecting with operation panel, and
SCIB is the terminals of 485+ and 485−.
Slave mode: In common applications, the inverter operates in slave mode (PC.04=0) and responses to
external instructions.
In the master mode, the inverter actively sending running frequency to other devices, this function is
often applied in multi-machines operate synchronously applications.
When master mode is selected, this inverter is set as a master to send running frequency to other
inverters. When the slave receives frequency sent from the master, it will store the frequency to the
parameter determine by master parameter PC.05. For example, if the master sending running frequency
to salve parameter P0.05, set master parameter PC.05 to 0.
If inverter master mode is set for SCIATSCIB and operation panel has been inserted, the operation panel
will get priority, and the function of inverter as master mode will lose effect automatically. If the operation
panel is removed, after T0 seconds the inverter will return to master mode.
PC.06 slave setting frequency proportional coefficient (set by the slave):
The parameter is only enabled for the slave, it is used to set the slave data coefficient receive from the
master.
