To reduce motor noise at
low speeds, set L8-17 to “0”
and L8-19 to “1”.

When high torque is
required at low speeds, set
L8-17 to “1” and L8-19 to
“0”.
Note: Do not set both L8-17 and
L8-19 to “0”. Doing so
may damage the inverter.
Use a larger inverter if
high torque is required

high torque is required
and you want to set a
higher carrier frequency.
Note: If flux vector control is be-
ing used and a large load
is being applied continu-
ously at low speed, either
use a larger inverter or
set the carrier frequency
to 2 kHz in C6-01.
