
C0-06 (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 10.00 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.

C0-07 (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. Then the adjustment amplitude reaches the maximum frequency.

C0-08 (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.

In some applications, PID parameters switchover is required when one group of PID parameters cannot satisfy the
requirement of the whole running process.
These parameters are used for switchover between two groups of PID parameters. Regulator parameters C0-09 ~
C0-11 are set in the same way as C0-06 ~ C0-08.
The switchover can be implemented either via a DI terminal or automatically implemented based on the deviation.
If you select switchover via a DI terminal, the DI must be set with function 43 "PID parameter switchover". If the
DI is OFF, group 1 (C0-06 ~ C0-08) is selected. If the DI is ON, group 2 (C0-09 to C0-11) is selected.
If you select automatic switchover, when the absolute value of the deviation between PID feedback and PID
setting is smaller than the value of C0-13, group 1 is selected. When the absolute value of the deviation between
PID feedback and PID setting is higher than the value of C0-14, group 2 is selected. When the deviation is
between C0-13 and C0-14, the PID parameters are the linear interpolated value of the two groups of parameter
values.
