9.2.10
Increasing the output frequency
9.2.10.1
Description
In applications that require higher output frequencies, the pulse frequency of the converter
may have to be increased.
It may also be necessary to change the pulse frequency to prevent resonances from
occurring.
Since increasing the pulse frequency also increases the switching losses, a derating factor
for the output current must be taken into account when the drive is configured.
Once the pulse frequency has been increased, the new output currents are automatically
included in the calculation for power unit protection.
Note
Use of a sine-wave filter (option L15) must be selected using p0230 = 3 when
commissioning. This setting fixes the pulse frequency to 4 kHz or 2.5 kHz and it cannot be
changed.
