• The service life of the frequency converter/ servo drive with intermediate voltage circuit
depends on the current load of the electrolytic capacitors in the intermediate circuit. The
use of mains chokes can increase the service life of the condensators to a considerable
extent, especially when connecting to „hard" power systems or when under permanent
drive load (continuous duty).
For continuous duty (S1) drives with a medium duty of >60%, KEB recommends the use
of mains chokes with a terminal voltage (Uk) of 4%.
The term "hard" mains can be defined as follows:
The rated power of the inverter (Sn) is very low compared to the nodal point power
(Smains). Example:
• When using a mains choke, it should usually be mounted on the mains side of the inter-
ference suppression filter.
