(same specifications as Pr. 71)
Second motor is invalid
PWM carrier frequency can be
changed. The setting displayed is
in [kHz]. Note that 0 indicates
0.7kHz, 15 indicates 14.5kHz and
25 indicates 2.5kHz. (25 is exclu-
sively for a sine wave filter.) The
following settings are for real sen-
sorless vector control and vector
control:
0 to 5: 2kHz, 6 to 9: 6kHz,
10 to 13: 10kHz, 14 to 15: 14kHz
* The setting depends on the
inverter capacity:
(01800 or less/02160 or more)
Soft-PWM invalid
When Pr. 72 = "0 to 5" ("0 to 4" for
the 02160 or more), Soft-PWM is
valid.
PWM carrier frequency is constant
independently of load.
When the carrier frequency is set
to 3kHz or more (Pr. 72 ≥ 3), per-
form continuous operation at less
than 85% of the rated inverter cur-
rent.
Decreases PWM carrier frequency
automatically when load
increases.
