Note 1: By
f300
setting and ambient temperature, current reduction may be required.
Refer to the table on the following page.
Note 2: PWM carrier frequency is increased automatically at high output frequency range (100 Hz or more) for
stable operation, even if
f300
is set to low PWM carrier frequency.
Note 3: When
f300
is set to 8kHz or less, the random mode is exercised in the low output frequency range
where an annoying magnetic noise of the motor is generated.
Select the proper tone from the three kinds of
f312
=
1
,
2
,
3
for the machinery.
Note 4: When
f316
is set to “Carrier frequency without reduction”,
oh
(overheat) or
ol3
(main module
overload) trip can occur easily.
Reduce
f601
or
f185
(stall prevention level) properly to avoid the trip.
Note 5: When reducing the voltage surge to the motor, set
f316
to
2
or
3
.
Use by setting
f300
to 4kHz or less, to avoid the output voltage drop.
Note 6: When reducing the voltage surge to the motor, set
f316
to
4
or
5
.
However, when the machinery (load) is resonated and the cable length between the inverter and the
motor is long (30m or more), use by setting
f300
to 4kHz or less.
