  • Page 6: Du/Dt Filter Range

    • vacon dU/dt filter range 2.dU/dt filter range 2.1 G ENERAL A pulsed PWM output voltage of an AC drive has typically a high rise time speed (6-8 kV/us) with an unloaded IGBT switch. When the motor cable and the motor are connected, the rise time will drop to 2-3 kV/us.
  • Page 7 • Figure 1. Change of the voltage shape in winding Voltage stress Figure 2. Voltage pulse reflection The maximum value of the reflected voltage is 2 x DC link voltage, in practice 1.8-1.9 x Udc. The voltage is fully developed at cables that are > 5 m.
  • Page 8 • vacon dU/dt filter range The filter, the cable and the motor form a complex high frequency circuit, which causes a voltage at the motor with different rise times and peak values depending on the cable length, type etc. Typical voltage peak values as function of cable length are as follows: Figure 3.

  • Page 11 • Between the converter output and the unit input (U1, V1, W1), use screened and/or twisted cables. Between the unit output (U2, V2, W2) and the motor, use shielded cables. If you use unscreened cables, make sure that the installation minimises the possibility of cross-coupling with other cables that are carrying sensitive signals.

    • vacon Safe operating curves 3 Safe operating curves The safe operating curves for dU/dt filters 130B2835 - 37 are shown in figures 12 and 13. It is assumed that the default cable type has a capacitance of 40 nF/100 m. The values should be scaled in accordance with the actual cable capacitance.
  • Page 17 Safe operating curves vacon • The safe operating curves for dU/dt filters 130B2838 - 40 are shown in figures 14 and 15. It is assumed that the default cable types have a capacitance of 45 - 55 nF/100 m. The values should be scaled in accordance with the actual cable capacitance. In case of multiple cables, the capacitance is the sum of the cable capacitances.
  • Page 18 • vacon Safe operating curves The safe operating curves for dU/dt filters 130B2841 - 43 are shown in figures 16 and 17. It is assumed that the default cable types have a capacitance of 55 - 60 nF/100 m. The values should be scaled in accordance with the actual cable capacitance. In case of multiple cables, the capacitance is the sum of the cable capacitances.

It is assumed that the default cable types have a capacitance of 60 - 65 nF/100 m. The values should be scaled in accordance with the actual cable capacitance. In case of multiple cables, the capacitance is the sum of the cable capacitances.
