Load capacity of the units at low output frequencies
The thermal model of MOVITRAC® B implements dynamic limiting of the maximum output current. Consequently, the thermal model only permits less than 100% nominal current at output frequencies less than 2 Hz if the capacity utilization is high.
In such operating states, configure the average output current of the inverter to max. 70% of the rated inverter current.
INFORMATION
The output frequency of the inverter comprises the rotational frequency (= speed) and the slip frequency.
Guaranteed continuous currents depending on the output frequency:
