Motor cable length, with output filter du/dt

Longer motor cables can be used after taking appropriate measures, e.g. use of low-capacitance ca-
bles and output filters. The following table contains recommended values for the use of output filters.

Motor cable length, with sinus filter

Motor cables can be longer if sinus filters are used. By conversion in sinus-shaped currents, high-
frequency portions which might limit the cable length are filtered out. Consider the voltage drop
across the cable length and the resulting voltage drop at the sinus filter. The voltage drop results in
an increase of the output current. The frequency inverter must be suitable for the higher output cur-
rent. This must be considered in the projecting phase.
In the case of motor cable lengths exceeding 300 m, contact BONFIGLIOLI service.
5.6.4

Group drive

In the case of a group drive (several motors at one frequency inverter), the total length must be di-
vided across the individual motors according to the value given in the table. See chapters 5.6.1 and 0.
Use a thermal monitoring element on each motor (e.g. PTC resistor) in order to avoid damage.
A group drive with synchronous server motors is not possible.
