Using filters
The filters are divided into various function and current ranges.
Filter types:
Input-side filters: filters on the power supply side
Motor-side filters: filters that are connected between controller and motor in the motor
phases

4.3.5.1
Input-side filters
These filters are for applications that either cannot use the motor filter (e.g., integrated
controllers) or in which the filtering by the motor filters is not sufficient. In this case, two fil-
tering measures are used:
Measure comparable to large capacitors (approx. >100
μ
F) as close as possible to the
controller and, where possible, low-ESR capacitances
Discharge of common-mode interference with a common-mode choke, a low-pass filter
and capacitors between functional earth and DC power supply
4.3.5.2
Insulation resistance
The filters from FAULHABER are not intended for an insulation resistance test. Discharging
of the common-mode interference with capacitors prevents a meaningful result from an
insulation resistance test.
Filters on the motor side must not be used in the MCS.
