Reaction: When the PID feedback signal is less than a given amount, the inverter output
frequency drops. Such as the tension of the tension control occasions. This function is
affected by the direction of the multi-function terminal PID action (function 35), the need
to pay attention.

PID given feedback range is dimensionless units for PID reference display d0-15 and PID
feedback display d0-16.
The relative value of the given feedback of the PID is 100.0%, corresponding to the given
feedback range PA-04. For example, if the PA-40 is set to 2000, the PID reference display
d0-15 is 2000 when the PID is set to 100.0%

Proportional gain KP1
：
Determine the adjustment strength of the entire PID regulator, KP1 the greater the greater
the intensity of regulation. The parameter 100.0 indicates that when the PID feedback
amount and the deviation of the given quantity are 100.0%, the PID regulator adjusts the
output frequency command to the maximum frequency
Integration time Ti1
：
Determine the strength of the PID regulator integral adjustment. The shorter the
integration time, the greater the adjustment intensity. The integral time is when the PID
feedback and the given amount of deviation of 100.0%, the integral regulator through the
time continuous adjustment, adjust the amount to reach the maximum frequency.
Derivative time Td1
：
Determine the strength of the PID regulator to adjust the rate of change. The longer the
differentiation time, the greater the intensity of regulation. The derivative time means that
when the amount of feedback changes by 100.0% over that time, the adjustment of the
differential regulator is the maximum frequency.

In some cases, it is possible for the PID to control the same amount of feedback to
the same state only when the PID output frequency is negative (ie, the inverter is reversed),
but the excessive inversion frequency is not allowed for some occasions , PA-08 is used
to determine the reverse frequency upper limit.
