Page 9: General
1 General 1 General The NORDAC PRO (SK 500P - SK 550P) series is based on the tried and tested NORD platform. The frequency inverters are characterised by their compact design and optimum control characteristics, and have uniform parametrisation. The frequency inverters have sensorless current vector control with a wide range of settings. In combination with suitable motor models, which always provide an optimised voltage/frequency ratio, all three-phase asynchronous motors that are suitable for inverter operation and permanently excited synchronous motors can be driven.

A reduction of the overload capacity or its duration must be considered for the following circumstances: •...
Page 235: Reduced Overcurrent Due To Time
8 Additional information 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 236: Reduced Overcurrent Due To Output Frequency
NORDAC PRO (SK 500P) – Manual with installation instructions 8.4.3 Reduced overcurrent due to output frequency To protect the power unit at low output frequencies (<4.5 Hz) a monitoring system is provided, with which the temperature of the IGBTs (insulated-gate bipolar transistor) due to high current is determined.
Page 237: Reduced Output Current Due To Low Voltage
8 Additional information 8.4.4 Reduced output current due to low voltage The frequency inverters are thermally designed with regard to the rated output currents. For lower low voltages larger currents cannot be used in order to keep the output power constant. For mains voltages above 400 V the permissible output current is reduced inversely proportional to the mains voltage in order to compensate for switching losses.
