Features and benefits
Improvement of system reliability
Add-on output filter module for the use with FN
5040 / 45 or FN 5020 sine wave output filters with
corresponding current rating.
Elimination of premature motor failure caused by
bearing damage.
Eliminates interference propagation towards
components or conductors in the vicinity.
Restricts pulse currents to ground and hence limits
leakage currents in the PE.
Allows the use of extremely long unshielded motor
cables without causing radiation problems (EN
55014, MDS clamp).
Reduces the required EMI suppression efforts on the
line side.
Allows the use of lower rated drives with long motor
cables due to lower losses in the IGBTs and in the
motor cable.
Suitable for rotating fields up to 600 Hz.

Typical block schematic
Temperature monitoring function
All filters of this range are equipped with a temperature monitoring function. The built- in temperature sensor opens a potential-free contact in the case of filter
overtemperature (>120C).
The maximum switching capability is 6 A/250 V. This function can be used, for example, in the input of a CNC controller or as the trip of a circuit breaker in order to
interrupt the mains power supply. Connections are located next to the phase con- nectors (see mechanical data for details).
Forced cooling
The 75 A and 120 A filters provide internal cooling fans which require external power supply (24 VDC/~4 W). Connections are located next to the connectors of the
temperature sensor (see mechanical data for details).
Connection to the dc link
For best results, the connection to the dc link of the motor drive is required with this series of filters.
If only one connection to the dc link is brought out of the drive (+ or -) then the dc link cable connections from the filter (identified by DC+ and DC- must be
connected together to the + or - motor drive connection.
The operation of the add-on sine wave output filter is not seriously affected as a result. The + and - connections on the motor drive must never be connected
together. Otherwise a short-circuit will result.
The PWM switching frequency must lie within the range from 6 to 15 kHz in order to ensure satisfactory operation of the filter. A lower switching frequency or a pure
square wave is unsuitable and will result in the motor drive switching off with the error message overcurrent or short to earth.
