These
two
parameters
are
respectively
used
to
set
the
detection
value
of
output
frequency
and
hysteresis
value
upon
cancellation
of
the
output
.
The
value
of
P8

is
a
percentage
of
the
hysteresis
frequency
to
the
frequency
detection
value
(

If the AC drive running frequency is within the certain range of the set frequency
,
the
corresponding
DO
terminal
becomes
ON
.
This parameter is used to set the range within which the output frequency is detected
to reach the set frequency
.
The value of this parameter is a percentage relative to the
maximum frequency
.
The
