It

to
change the input specification
(terminal

according to the frequency reference
vdiage
“1.
If
voltage
d
0

should
be
input, change
the

to
equal
the
input specification.

1.
To change the maximum output frequency corresponding
to
the input of the max-
imum frequency command vottage (current), value
should
be
changed for Pr.903
(frequency setting voltage gain) or Pr.905 (frequency setting current gain).
It
is not
necessary
to
input a command voltage (current).
The
acceleration/deceleration
time is not influenced by a change in Pr.73 setting
since
it
defines the gradient
up
to
the
acceleration/deceleratbn
reference frequen-
cy.
2.
Set
“0”
for Pr.72 when the inverter
is
operated with a frequency reference poten-
tiometer connected.
*The inverter can
be
operated by the frequency
setting current signal
(4
to
20mA
DC).
If the cur-
rent input signal function is set for the
RWAU
ter-
minal,
it
is possible by closing the circuit across
terminals
AU
and
SD
to use this function.
The external
run
terminal function can be set for
the starting command and rotation command.

is possible
to
select
the
reset function for terminal

It is also possible for the parameter
unit disconnection alarm function
to
be selected
if
the parameter unit is
disconnected.

if
the inverter is operated without selecting the parameter unit disconnection detection function,
inverter operation will
be
continued even after the parameter
unit
is disconnected from the in-
verter, which will create hazardous situation.
*Therefore.
to
ensure safe operation, it
is
racommended
that the parameter unit disconnection
detection
function
be
sewed.
*The
stop
key
on
the parameter unit can
be
activated
to
work in al operation modes.
