Actual signals and parameters 243
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.
See also parameter 2607 SWITCH FREQ CTRL and
section Switching frequency derating, I2N on page 376.
4kHz
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 2606 SWITCHING
FREQ is 4 kHz.
ON
(LOAD)
ON Drive maximum current is automatically derated according
to the selected switching frequency (see parameter 2607
SWITCH FREQ CTRL and section Switching frequency
derating, I2N on page 376) and adapted according to the
drive temperature.
It is recommended to use this selection when a specific
switching frequency is required with maximum performance.
