Chapter 6 Parameter Description
113
PC.04 master-slave mode:
0: SCIA is slave mode and SCIB is slave mode;
1: SCIA is master mode and SCIB is slave mode;
2: SCIA is slave mode and SCIB is master mode.
PC.05 master to slave operation address (set by master), position for writing slave function code to
master setting frequency:
0: P0.05 1: P8.00 2: P8.01
The inverter provides two communication ports. SCIA is a port connecting with operation panel, and
SCIB is used terminal for 485+ and 485-.
In common applications, the inverter operates under slave mode (PC.04=0) and responses to external
instructions.
Master mode: To active sent data to outside, which is often applied when multi-machines operate
synchronously. When selecting master mode, one unit in a group of units often is set as a master to
transfer operating frequency instructions to other units. When the slave receives frequency instructions
from the master, it will store these instructions at the position of function code specified by PC.05. For
example, if open loop digital frequency is given, adopt P0.05 as frequency reference and set PC.05=0.
If inverter master mode is set for SCIA/SCIB and operation panel has been inserted, the operation panel
will take priority of controlling, and the function of inverter as master mode will lose effect automatically.
Pull out the operation panel, after 10 seconds the inverter will return back to master mode.
PC.06 slave setting frequency proportional coefficient (set by the slave):
The parameter is only valid for the slave and is used to set the slave to receive correction coefficient
specified by the master.
Slave setting=PC.06 × master reference.
6.14 Vector Control 2 Parameters (Group Pd)
This group of functions is only valid for vector control 2. They are invalid for Vector control 1.
Note: The series of V5-H is only support speed model upon vector control, if torque control model
upon vector control is needed, please select the product series of V6-H.
