Power loss of components in rated operation

12.9.4.1

General information

The tables below provide an overview of the power loss of all components during rated
operation. The characteristic values apply for the following conditions:
● Line supply voltage 400 V
● Pulse frequency of the Motor Modules 4 kHz (clock frequency of the spindle 4 kHz or 8
kHz)
● Operating components at their rated power
The total losses of the relevant components (S120 Combi, Motor Module) are calculated
from the power loss and the corresponding losses from the electronics.
