the
method
for
adjusting
the
frequency
reference
using
pulse
inputs.

example
This
example
results
in
an
output
frequency
of
30
Hz
when
a
2-kHz
pulse
is
input
(maximum
frequency:
60
Hz).

nSetting
precautions
The
pulse
train
inputs
of
the
Inverter
do
not
control
positioning
as
they
do
for
servomotors
and
stepper
motors.
Speed
control
is
thus
absolutely
necessary.
Make
adjustments
with
the
following
procedure.
1. First,
adjust
the
pulse
train
input
bias
setting.
Adjust
the
output
with
respect
to
the
pulse
input
near
the
minimum
output
frequency.
2. Next,
adjust
the
pulse
train
input
gain
setting.
Adjust
the
output
with
respect
to
the
pulse
input
near
the
maximum
output
frequency.
