Description
It
determines
the
regulation made on the change rate of
deviation between PID feedback and
reference by PID regulator. If feedback
changes by 100% during this period, the
regulation
of
(ignoring integral and differential actions)
is max. output frequency (P00.03) or max.
voltage (P04.31).
The longer the derivative time, the
stronger the regulation intensity. Setting
range: 0.00–10.00s
It means the sampling cycle of feedback.
The regulator operates once during each
sampling cycle. The larger the sampling
cycle, the slower the response.
Setting range: 0.001–10.000s
It is the max. allowable deviation of PID
system output value relative to closed-loop
reference value. Within this limit, PID
regulator
stops
function code properly to regulate the
precision and stability of PID system.
