300.0

 

Set the proportional gain for PID control. When P-Gain is set at 100% and I-Gain at 0.0 second, it means the PID controller output is 100% for 100% error value.

This code sets the second P-Gain for PID control. The second P-Gain is can be selected for PID controller by setting a multi-function input (I/O-12 ~ I/O14 or EXT-02 ~ EXT-04) to ‘Open-loop’.

This code sets the scale of P-Gain and P2-Gain. (FU2-52, FU2-59)

PID output value can be set to ‘0’ by setting a multi- function input terminal (P1 ~ P6) to ‘Open loop’ in I/O- 12 ~ I/O-14 or EXT-02 ~ EXT-04.

The accumulated value by I-Gain can be set to ‘0’ by setting a multi-function input terminal (P1 ~ P6) to ‘iTerm Clear’ in I/O-12 ~ I/O-14 or EXT-02 ~ EXT-04.
