7.2 Continuous thermal output
If the pulse frequency (P504) of the power end stage is increased, deviating from the standard settings, this will lead to a
reduction in continuous output power. The corresponding trend can be seen in the following diagram. The power loss is approx.
5% of the inverter nominal power (kW).
Diagram is valid
for 1.5...160kW devices
