Tab. 26: Power loss data of the SC6 drive controller in accordance with EN 61800-9-2
General conditions
The specified losses apply to a drive controller. They apply to both axes together in the case of double-axis controllers.
The loss data applies to drive controllers without any accessories.
The power loss calculation is based on a three-phase supply voltage with 400 V
AC
/50 Hz.
The calculated data includes a supplement of 10% in accordance with EN 61800-9-2.
The power loss specifications refer to a clock frequency of 4 kHz.
The absolute losses for a power unit that is switched off refer to the 24 V
DC
power supply of the control electronics.

Absolute losses for a power unit that is switched off
3
Operating points for relative motor stator frequency in % and relative torque current in %
4
IE class in accordance with EN 61800-9-2
5
Comparison of the losses for the reference drive controller relative to IE2 in the nominal point (90, 100)
