2606 SWITCHING
FREQ
Defines the switching frequency of the drive. Higher
switching frequency results in lower acoustic noise.
In multimotor systems, do not change the switching
frequency from the default value.

section
Switching frequency derating, I2N
4 kHz
4 kHz
Sets the switching frequency to 4 kHz.
1 = 1 kHz
8 kHz
Sets the switching frequency to 8 kHz.
12 kHz
Sets the switching frequency to 12 kHz.
16 kHz
Sets the switching frequency to 16 kHz.
2607 SWITCH FREQ
CTRL
Selects the control method for the switching frequency.
Selection has no effect if parameter
is 4 kHz.
ON
Drive maximum current is automatically derated according
to the selected switching frequency (see parameter
and section
on page
) and adapted according to the
drive temperature.
It is recommended to use this selection when a specific
switching frequency is required with maximum performance.
