LSIS sv-ip5a - Dual PID Block Diagrams

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; ①controlling other system independently like an external PID
controller ②using both PID controller in APP-02 and External PID controller ③using ExtPID output as an
Inverter target frequency.

This illustrates controlling other system independently. Set I/O-70 or 72 [S0/S1 mode] to “Ext PID Out” 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.
