Default
P09.06
Differential time
(Td)
Used to determine the strength of the change
ratio adjustment on the deviation of PID feedback
and reference from the PID regulator. If feedback
quantity changes 100% during this time period,
the range within which the differential regulator
(ignoring integral function and differential
function) can regulate is the max. frequency
(P00.03).
Longer differential time indicates stronger
adjustment.

PID control
deviation limit
The feedback value of the PID system is relative
to the max. deviation of the closed loop reference.
The PID regulator stops regulating in the range of
deviation limit. Set the function parameter
properly to adjust the accuracy and stability of the
PID system.
