Filters have leakage currents which may be considerably greater than
the rated values in the event of a fault (phase failure, unbalanced load)
(see section entitled “Leakage current”).
Please note the following if additional filter measures are required:
` Earth the filter to avoid hazardous voltages
` Leakage currents are high frequency disturbances, so earth the filter
at low impedance over a wide area.

6.5.4 Chokes
Chokes 6- ][EMV_Drosseln
If motor cables are > 25 m, a choke must be used on the servo amplifi-
er's output.
The choke is used to:
` Reduce the level of interference on the motor cable
` Deal with EMC problems retrospectively
` Protect the semiconductor on the inverted rectifier in the case of an
earth fault or short circuit
` Protect the motor from high voltage rise rates
Additional earthing measures are unnecessary because, unlike filters,
chokes do not have to divert disturbances to earth.
WARNING!
In a residential environment this product may cause high-fre-
quency noise, so that suppression measures may be required.
