For approx. 3.5 s a 2x overcurrent is possible. A reduction of the overload capacity or its time must be taken into account in the following circumstances: •...

  • Page 206: Reduced Overcurrent Due To Time

    NORDAC PRO (SK 500P) – Users Manual for Frequency Inverters 8.4.2 Reduced overcurrent due to time The possible overload capacity changes depending on the duration of an overload. Several values are cited in this table. If one of these limiting values is reached, the frequency inverter must have sufficient time (with low utilisation or without load) in order to regenerate itself.

  • Page 207: Reduced Overcurrent Due To Output Frequency

    8 Additional information 8.4.3 Reduced overcurrent due to output frequency To protect the power unit at low output frequencies (<4.5Hz) a monitoring system is provided, with which the temperature of the IGBTs (insulated-gate bipolar transistor) due to high current is determined.
