PA-05 (Proportional gain Kp1)
It decides the regulating intensity of the PID regulator. The higher the Kp1 is, the larger the regulating intensity
is. The value 100.0 indicates when the deviation between PID feedback and PID setting is 100.0%, the
adjustment amplitude of the PID regulator on the output frequency reference is the maximum frequency.
• PA-06 (Integral time Ti1)
It decides the integral regulating intensity. The shorter the integral time is, the larger the regulating intensity is.
When the deviation between PID feedback and PID setting is 100.0%, the integral regulator performs
continuous adjustment for the time set in PA-06. Then the adjustment amplitude reaches the maximum
frequency.
• PA-07 (Differential time Td1)
It decides the regulating intensity of the PID regulator on the deviation change. The longer
the differential time is, the larger the regulating intensity is. Differential time is the time within which the
feedback value change reaches 100.0%, and then the adjustment amplitude reaches the maximum
frequency.

Max frequency
In some situations, only when the PID output frequency is a negative value (AC drive reverse rotation), PID
setting and PID feedback can be equal. However, too high reverse rotation frequency is prohibited in some
applications, and FA-08 is used to determine the reverse rotation frequency upper limit.

100.0%
If the deviation between PID feedback and PID setting is smaller than the value of PA-09, PID control stops.
The small deviation between PID feedback and PID setting will make the output frequency stabilize, effective
for some closed-loop control applications.

It is used to set the PID differential output range. In PID control, the differential operation may easily cause
system oscillation. Thus, the PID differential regulation is restricted to a small range.
