Typical measurement results dv/dt without FN 510 dv/dt with FN 510 Overvoltages without FN 510 Overvoltages with FN 510 dv/dt reduction: maximum dv/dt at the motor terminals, measured with the motor drive operating at 14 kHz switching frequency, 5 m of shielded cable, motor with 100% load. Overvoltage limitation: maximum overvoltages at the motor terminals, measured with the motor drive operating at 14 kHz switching frequency, 80 m of shielded cable, motor idling. Typical application range at different operating conditions The power loss in the filter depends mainly on the switching frequency (fs) of the motor drive and the length of the motor cable. FN 510 have been designed for an ambient temperature of 50C. Other conditions can, however, occur in practice. In such cases, care must be taken to limit the maximum cable length and/or the switching frequency of the motor drive, depending on the real ambient temperature conditions. FN 510 are designed for: Possible application, e.g.: 50C 16 kHz 50 m Tamb. Max. fs Max. cable 50C 10 kHz 80 m 40C 16 kHz 80 m Temperature monitoring function The temperature monitoring device opens a potential-free contact in the case of filter overtemperature (>120C). The maximum switching capability is 5 A/240 V. The switch 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.
