Rated data for capacitor modules
The ECS servo system is ideal for use in dynamic multi-axis
applications. As, depending on the specific conditions, operat-
ing modes may be used in these applications which require
significantly increased DC-bus power for longer periods of
time, ECS capacitor modules have been provided. These
modules will optimise the dimensioning of the required DC-
bus capacity for the specific application.

Capacitor module dimensioning
The following values must be calculated to determine
whether a capacitor module is required:
ƒ
C: Total capacity of DC-bus connection in µF
ƒ
P: Temporal average of total active power of all drives in
kW
Use the following formula:
If k
≥
100 (µF/kW), a capacitor module will generally not be
required.
