2 Assembly and installation 2.11.8 DC-coupling (X2 - +B, -DC) In drive engineering, DC-coupling is advisable if motors act as drivers and generators at the same time in the system. Here, the energy from the drive which is acting as a generator can be fed back to the drive which is acting as a motor.
NORDAC SK 500E Manual (4) Ensure that the coupling is disconnected as soon as one of the devices is no longer ready for operation. (5) For a high availability a braking resistor (possibly lower power) must be used. If different sizes of frequency inverters are used, the braking resistor must be connected to the larger of the two frequency inverters.

NORDAC SK 500E Manual 8.2 Process controller The process controller is a PI controller which can be used to limit the controller output. In addition, the output is scaled as a percentage of a master setpoint. This provides the option of controlling any downstream drives with the master setpoint and readjusting using the PI controller.
EN 61000--62 and EN 61000-6-4 for interference immunity and interference emissions. ATTENTION NORDAC SK 500E Frequency inverters are intended exclusively for commercial use. They are therefore not subject to the requirements of the standard EN 61000-3-2 for radiation of harmonics.

NORDAC SK 500E Manual 8.5 Reduced output power The SK 5xxE frequency inverter series is designed for certain overload situations. For example, 1.5x overcurrent can be used for 60 sec. For approx. 3.5 sec a 2x overcurrent is possible. A reduction of the overload capacity or its time must be taken into account in the following circumstances: Output frequencies <...
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.
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.
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.
This is important in order to keep repair times as short and efficient as possible. On request you can also obtain a suitable return good voucher from Getriebebau NORD. Internet information You can find the comprehensive manuals in German and in English on our Internet site.
