Increasing the output frequency

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

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.

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
