Description
range
interval
between the
timed interrupt
tasks.
It is the
magnified
proportional
value of the
Range of
error between
positive
the SV and the
single-
PV. If the
precision
magnified
floating-
proportional
point
value of the
numbers
error is less
than 0, the K
will be count as
0.
Range of
It is the integral
positive
gain (K ). If the
i
single-
integral gain is
precision
less than 0, the
floating-
K will be count
i
point
as 0.
numbers
Range of
It is the
positive
derivative gain
single-
(K ). If the
d
precision derivative gain
floating- is less than 0,
the K will be
point
d
count as 0.
numbers
True: Reverse action
(E=SV-PV)
False: Forward action
(E=PV-SV)
The error value
(E) is the
difference
between the
SV and the PV.
Range of
When the
single-
setting value is
precision 0, the function
floating- is not enabled.
For example,
point
the E within the
numbers
range between
-5 and 5 will be
count as 0 if
the setting
value is 5 or -5.
