Chapter 6 - Parameter Description [APP]
6-74
APP-02 , APP-80 (to use Dual PID operation)
ExtPID can be used in the following three cases; ā controlling other system independently like an external PID
controller ā”using both PID controller in APP-02 and External PID controller ā¢using ExtPID output as an
Inverter target frequency.

(Other System)
This illustrates controlling other system independently. Set I/O-70 or 72 [S0/S1 mode] to āExt PID Outā and
connect external system to S0 or S1 terminal. When Ext.PID Run signal is ON at the defined terminal in I/O-
20~27, it starts output.
