CAUTION! DAMAGE TO THE DEVICE DUE TO OVERLOAD IN THE DC LINK!
x Carelessness may result in signicant damage.
The maximum overall capacitance of the multi-axis system DC link must not exceed the value
stated.
NOTE:
In the overall axis group, a DC link capacitance of ≥ 100µF/kW (for 3 x 400V)
or ≥ 170µF/kW (for 3 x 230V), referred to the highest rated power that
occurs, must be provided. This capacitance is determined by adding together
the capacitances of the individual devices. The root mean square of the active
power for a load cycle is dened as the active power.
