9. Calculate sum of leakage capacitance on load side of mains filter.
Determine sum of leakage capacitance from number of operated
axes and length of connected motor cables. Chapter "Calculations",
section "Determining the Leakage Capacitance" helps you with the
calculation.
10. Select appropriate mains filter from tables in chapter "Limit Value
Classes to be Achieved with Mains Filters".
Note: Observe that the capacity of the mains filters regarding the
max. allowed number of drive controllers and max. allowed
total motor cable length depends on whether you use an HMV
supply module or supply other drive controllers with HCS drive
controllers.
For supply by HMV both the allowed number and allowed total
length are higher.
11. Calculate allowed operating data of mains filter according to chapter.
If necessary, make sure the harmonics are reduced at installation
location.
Note: The selected mains filter has to comply with the criteria
determined before.
Within a mains filter line you can replace mains filters of lower
type current by such ones with higher type current.
For Rexroth drive systems there are the following mains filters for radio
interference suppression available:
• NFE01.1, NFE02.1, NFD03.1, HNF01.1, HNK01.1
These filters have been especially dimensioned for Rexroth drive
systems. If you use other filters by other manufacturers, Rexroth cannot
guarantee mains interference suppression with regard to allowed limit
values.
Protecting Mains Filters Against Overload
The mains filters are provided for operation with Rexroth IndraDrive
devices and due to their specific properties risk overload.
CAUTION
Property damage due to mains filter overload!
⇒ Avoid series connection of mains filters as this can
cause resonance effects on current and voltage.
⇒ When using mains filters at compensation units,
make sure there aren't any resonance effects on
current and voltage.
⇒ Observe the allowed harmonic limit values (THD) of
the filter components.
⇒ Observe that the nominal current of the mains
contactor does not exceed the nominal current of the
mains filter.
