less than the
absolute value of
ERR_DBW, and
check whether the
present error
meets the cross
status condition. If
the present error is
less than the
absolute value of
ERR_DBW, and
meets the cross
status condition,
the present error
will be count as 0,
and the PID
algorithm will be
implemented,
otherwise the
present error will
be brought into the
PID algorithm
according to the
normal processing.
MV_MAX
REAL
Maximum output
value
Range of
single-precision
floating-point
values
Example: After
MV_MAX is set to
1,000, an MV will
be 1,000 if it
exceeds 1,000.
MV_MAX has to
be greater than
MV_MIN,
otherwise the
maximum output
value set and the
minimum output
value set will be
interchanged.
MV_MIN
REAL Minimum output value
Range of
single-precision
floating-point
values
Example: After
MV_MIN is set to -
1,000, an MV will
be - 1,000 if it is
less than than
-1,000. MV_MIN
has to be lessthan
MV_MAX,
otherwise the
maximum output
value set and the
minimum output
value set will be
interchanged.
MOUT
REAL Manual output value
Range of
single-precision
floating-point
values
Mout and
PID_MAN are
used together. If
PID_MAN is set to
