Page 167: Reduced Overcurrent Due To Time
8 Additional information 8.5.2 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 168: Reduced Overcurrent Due To Output Frequency
NORDAC SK 500E Manual 8.5.3 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 (integrated gate bipolar transistor) due to high current is determined. In order to prevent current being taken off above the limit shown in the diagram, a pulse switch-off (P537) with a variable limit is introduced.
Page 169: Reduced Output Current Due To Mains Voltage
8 Additional information 8.5.4 Reduced output current due to mains voltage The devices are designed with thermal characteristics according to the nominal output currents. Accordingly, for lower mains voltages, higher currents cannot be taken off in order to maintain the stated power constant. For mains voltages above 400v there is a reduction of the permissible continuous output current, which is inversely proportional to the mains voltage, in order to compensate for the increased switching losses.
