    SK 180E Manual for frequency inverters 9.2 Process controller The process controller is a PI controller which can be used to limit the controller output. In addition, the out- put 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.

    9 Additional Information 9.4 EMC limit value classes Please note that these limit value classes are only reached if the standard pulse frequency (6kHz) is being used and the length of the shielded motor cable does not exceed the permissible limits. In addition, it is essential to use wiring suitable for EMC.

  • Page 164: Reduced Output Power

    SK 180E Manual for frequency inverters 9.5 Reduced output power The frequency inverter 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 <...

  • Page 165: Reduced Overcurrent Due To Time

    9 Additional Information 9.5.2 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.

    SK 180E Manual for frequency inverters 9.5.3 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.
