Note
The maximum and minimum possible pulse frequency is also determined by the power unit being used (minimum pulse
frequency: 2 kHz or 4 kHz).
When the pulse frequency is increased, depending on the particular power unit, the maximum output current can be
reduced (derating, refer to r0067).
If a sine-wave filter is parameterized as output filter (p0230 = 3), then the pulse frequency cannot be set below the
minimum value required for the filter.
For operation with output reactors, the pulse frequency is limited to 4 kHz (see p0230).
If p1800 is changed during commissioning (p0010 > 0), then it is possible that the old value will no longer be able to be
set. The reason for this is that the dynamic limits of p1800 have been changed by a parameter that was set when the
drive was commissioned (e.g. p1082).
The pulse frequency cannot be changed when the motor data identification is activated.

Access level: 2
(PM330)
Can be changed: T, U
Unit group: -
Min:
0.500 [kHz]
Description:
Sets the drive converter switching frequency.
This parameter is pre-set to twice the rated converter value when the drive is first commissioned.
Dependency:
Minimum pulse frequency: p1800 >= 12 * p1082 * r0313 / 60
