6.10 Choke
Technical specifications for suitable chokes can be found in the following chapters.
6.10.1 TEP output choke
Output chokes are required for drive controllers of sizes 0 to 2 and for a cable length of 50m or
longer in order to reduce interference pulses and protect the drive system.
Information
The following technical data only applies to a rotating magnetic field frequency of 200Hz. For
example, this rotating magnetic field frequency is achieved with a motor with 4 pole pairs and a
nominal speed of 3000rpm. Always observe the specified derating for higher rotating magnetic
field frequencies. Also observe the relationship with the clock frequency.

Project configuration
Select the output chokes in accordance with the nominal currents of the output chokes, motor
and drive controller. In particular, observe the derating of the output choke for rotating magnetic
field frequencies higher than 200Hz. You can calculate the rotating magnetic field frequency for
your drive with the following formula:
