Note The
V/f pattern is a straight line if there is no dif
ference between n015 and n017 in set value, in
which case the set value of n016 will be ignored.
H Interruption Mode and Protective Function Selection (n003, n004,
n008, n032, and n033)
S Set the input voltage of the Inverter to determine the voltage protective level of the Inverter.
n003 Input Voltage Selection
Setting range 150.0 to 255.0
(510.0)
Unit V Default setting 200.0 (400.0)
S Set the stop mode of the Inverter with n004.
n004 Interruption Mode Selection
Setting range 0 to 3 Unit --- Default setting 0
Set Values
Set value Description
0 Deceleration stop (See notes 1 and 2.)
1 Free running stop (See note 3.)
2 Free running stop 1 with timer. The run command during acceleration time 1 or 2 will be ignored.
3 Free running stop 2 with timer. The constant run command is valid. The motor will start running
after deceleration time 1 or 2 passes.
Note 1. If multi-function inputs 1 to 5 (n035 to n039) are not set to acceleration/deceleration time
switching
command (set value: 12), the motor will decelerate to a stop according to the setting
of
deceleration time 1 (n020). If any one of the multi-function inputs is set to acceleration/de
-
celeration
time switching command, then the motor will decelerate according
to the decelera
-
tion time selected at the time the stop signal is input.
Note 2. If
a run signal is input while the motor is decelerating, deceleration will stop and the motor will
accelerate at the same rate.
Note 3. During
free running stop, do not input the run signal if the speed at
which the motor is rotating
has
not dropped suf
ficiently
. If
the run signal is input in this state, the motor will be decelerated
to a low frequency very rapidly, and an overvoltage and overcurrent will be detected.
In this case, use free running stop (1 or 2) with timer, and set deceleration times that will
ensure
that the speed of the motor has reduced suf
ficiently
. (In either case, the motor will not
start running before the deceleration time has passed.)
To
start running
during free running stop, turn ON speed search for one of the multi-function
inputs 1 to 5 (n035 to n039). Speed search will detect when the motor has reached an
appropriate speed to start running.
S Set n008 so that the STOP/RESET Key will function properly.
n008 Stop Key Function Selection
Setting range 0, 1 Unit --- Default setting 1
Set Values
Set value Description
0 The STOP/RESET Key will function only when the Inverter is running with the run command
through the Digital Operator.
1 The STOP/RESET Key will be available anytime.
