● HNL mains choke
● If necessary, combination of mains filter and HNK mains choke
● Mains contactor (integrated for some HMV)
Notes on Project Planning
From the tables in the following chapters, select the mains connection for the
projected supply (HMV or HCS) and take the given values into account. If
necessary, split the drive system up or use a more powerful mains filter (e.g.,
type "M900" instead of type "F240").
● C
y
(capacitance against housing)
This capacitance must be charged by the supply unit or converter when
the mains voltage is switched on and is limited by the charging ability of
the supply units and converters.
In the technical data, you can find the value of C
y
for each component at
the DC bus.
The value C
y
mustn't fall below the required minimum value to attenuate
and avoid oscillation in the mains connection.
● Max. number of axes
The allowed number of axes is limited by the mains filter, because the
leakage current generated by the drive system loads the mains filter.
● Max. leakage capacitance C
ab_g
Due to the leakage capacitance (capacitance of cables and motor),
leakage current, which loads the mains filter, is generated by the switch‐
ing at the output of the inverter.
In the column "EMC limit value class to be achieved", you can find, for
the selected mains connection (mains filter, mains choke), the leakage
capacitance with which the combination can comply with the respective
EMC limit value class.
● Motor cable length
The length of the motor cable determines the leakage capacitance. With
the switching frequency which has been set, the leakage current is gen‐
erated due to the leakage capacitance. The specified values of the mo‐
tor cable length (switching frequency f
s
) cause the same load and filter
effect at the mains filter and are to be understood as guide values.
