The feedback amount of the process PID is also a relative value, and the setting range is 0.0 % - 100.0 %.

0: positive effect
When the feedback signal of PID is less than a given amount, the output frequency of the frequency inverter
increases. Such as tension control occasions for winding.
1: reaction.
When the feedback signal of PID is less than a given amount, the output frequency of the frequency inverter will
be decreased Such as tension control occasions for unwinding.
This function is affected by the reversal of the direction of action of the multi-function terminal PID (function 35),
which requires attention in use.

PID given feedback range is dimensionless unit, used for PID given display U0 - 15 and PID feedback display u0
- 16.
The relative value of the given feedback of PID is 100.0 %, corresponding to the given feedback range FA - 04.
For example, if FA - 04 is set to 2000, when the PID is given 100.0 %, the PID given display u0 - 15 is 2000.

Proportional gain Kp1:
Determining the adjusting intensity of the whole PID regulator, the greater kp1, the greater the adjusting intensity.
The parameter is 100. 0 indicates when PID is inverted when the deviation between the feed quantity and the given
quantity is 100.0 %, the regulating amplitude of the PID regulator to the output frequency command is the maximum
frequency.
Integration time Ti1:
Determines the strength of integral adjustment of PID regulator. The shorter the integration time, the greater the
adjustment intensity the integration time refers to when the deviation between the PID feedback quantity and the
given quantity is 100.0 %, the integral regulator continuously adjusts after this time, and the adjustment quantity
reaches the maximum frequency.
Differential time Td1:
Determines the strength of the PID regulator to adjust the deviation rate of change. The longer the differentiation
time, the greater the adjustment intensity Differential time it means that when the feedback amount changes by
100.0 % within this time, the adjustment amount of the differential regulator is the maximum frequency.

00 ~ maximum frequency [0.00 Hz]
In some cases, only when the output frequency of the PID is negative ( i.e. the frequency inverter inverts ), can
the PID control the given amount and the feedback amount to the same state, but too high an inversion frequency is
not allowed in some cases, and FA - 08 is used to determine the upper limit of the inversion frequency.
FA - 09 PID deviation limit 0. 0%
～
100.0% [0.0%]
When the deviation between the given PID quantity and the feedback quantity is less than FA - 09, the PID stops
the adjusting action, and the output frequency is stable when the deviation between the given quantity and the
feedback is small.
