Reaction
Positive action: when the feedback information of PID is less than the given value, the output frequency of
frequency converter shall go up. For example, the winding tension shall control occasions.
Reaction: when the PID feedback information is less than the given value, the output frequency of
frequency converter shall fall. For example, the unwinding tension shall control occasions.
The function shall withstand the negation impact of multifunction terminal PID (Function 35) and we must
notice the impact when we put it into use.

PID given feedback measurement value means dimensionless unit and it is used for PID given display
U0-15 and the PID feedback display U0-16.
The relative value 100.0% of PID given feedback corresponds to the given feedback measurement range
FA-04. For example, if we set the FA-04 for 2000, when the PID gives 100.0%, the PID given display
U0-15 shall be 2000.

Proportional gain Kp1:
It decides the adjusting strength of whole PID regulator, which is intensified along with the growing of Kp1.
when Kp1 is 100.0, it indicates that the adjusting range of PID regulator towards the output frequency
instruction reaches its biggest when the feedback value and set value deviation of PID is 100.0%.
Integral time Ti1:
It decides the integral adusting intensity of PID regulator. The shorter the integral time is, the greater the
intensity. Integral time indicates that when feendback value and given value deviation of PID is 100.0%, the
adjustment amount of the integral regulator reaches its biggest after stepless regulation in the given time.
Derivative time Td1:
It decides the adusting instensity of PID regulator towards the deviating rate. The longer the derivative time
is, the greater the intensity. Derivative time indicates that the adusting amount of derivative regulator
reaches its biggest when the change of the feedback value is 100.0% at that time.
