mains filter
● Harmonics on mains voltage on site
● Loading by mains voltage and mains frequency on site
● Loading by harmonics on site
● Loading by mains-side phase current
● Total length of connected power cables
● Sum of leakage capacitances
● Clock frequency of drive controller
The selection of the mains filter is significantly determined by the operating
conditions.
How to proceed for selecting the mains filter:
1. Determine the required EMC limit value class for the application.
2. Determine the maximum applied mains voltage. Observe that all
Rexroth IndraDrive Cs mains filters are not suited for a mains voltage of
3 AC 500 V.
Check whether the mains voltage of the mains filter is loaded with har‐
monics and still allowed for the mains filter.
If necessary, reduce the harmonics on site.
3. Determine the mains connection type, such as central supply, group
supply, etc. (To do this, it is useful to outline the involved components
and their interaction.)
4. Calculate the mains-side phase current of the mains filter. You can find
the procedure for calculating the mains-side phase current in a separate
chapter (see chapter "Calculating the mains-side phase current " on
page 85). For selecting the components, calculate the effective rms val‐
ue.
Check or determine the maximum occurring ambient temperature. Se‐
lect a mains filter with a higher nominal current, if the ambient tempera‐
ture is above 45 °C.
5. The nominal current of the selected mains fuse should not exceed the
nominal current of the mains filter.
6. Determine the number of drive axes.
7. Determine the total length of the connected power cables.
8. Determine the sum of the leakage capacitances on the load side of the
mains filter. The sum of the leakage capacitances results from the num‐
ber of operated axes and the length of the connected power cables. You
can find the procedure for determining the leakage capacitance in a
separate chapter (see
tance" on page 325).
9. Take the clock frequency of the drive controller into account.
The higher the clock frequency of the drive controller, the higher the
leakage currents and the interference emissions they involve.
The following leakage capacitances (motor cable + motor) should not be
exceeded per drive controller.
