These functions are used to set PID control operation gains.
P (Proportional) gain,
gain, D (Differential) gain
Set each gain.

FUNC
Initial value
2
This function is used to control the PID functions incorporated in the inverter.
This function is also used to select a feed-back signal input and set a magnification of the integral
gain setting value.
For details of PID control, refer to "Appendix 8 PID Control Functions".
Setting method
2
FUNC
Initial value
Set "0" for the use of a PID optional board.
Do not assign a feed-back signal input and an target frequency command
to the same terminal. If assigned, the PID function will be disabled.
