dv/dt filter compact plus Voltage Peak Limiter
dv/dt filters compact plus VPL (

imiter) limit the
voltage rate-of-rise dv/dt to values of < 1600 V/
μ
s and the typical
voltage peaks to the following values in accordance with the limit
value curve A according to IEC 60034-25: 2007:
•
< 1150 V at
U
line
< 575 V
•
< 1400 V at 660 V <
U

< 690 V
The dv/dt filter compact plus VPL functionally consists of two
components that are supplied as a compact mechanical unit,
the dv/dt reactor and the voltage limiting network (VPL), which
limits voltage peaks and feeds back the energy to the DC link. It
is so compact that it can be completely integrated into the cab-
inet, even for high power ratings. A supplementary cabinet is not
required.
By using a dv/dt filter compact plus VPL, standard motors with
standard insulation and without insulated bearings can be used
with supply voltages up to 690 V in converter operation.
dv/dt filters compact plus VPL are designed for the following
maximum motor cable lengths:
•
Shielded cables: 100 m (e.g. Protodur NYCWY)
•
Unshielded cables: 150 m (e.g. Protodur NYY)
For longer cable lengths (> 100 m shielded, >150 m un-
shielded), the dv/dt filter plus VPL (option
L10
) should be used.
Notice:
•
Operation with output frequencies < 10 Hz is permissible for
max. 5 min.
•
The maximum permissible output frequency is 150 Hz.
The appropriate information in the SINAMICS Low Voltage
Engineering Manual should also be carefully observed.
Note:
Option
L07
cannot be combined with the following options:
•
L08
(motor reactor)
•
L10
(dv/dt filter plus VPL)
•
L15
(sine-wave filter)
•

(motor connection from above)
L08
Motor reactor
Motor reactors reduce the voltage load on the motor windings by
reducing the voltage gradients at the motor terminals that occur
during converter operation. At the same time, the capacitive
charge/discharge currents that place an additional load on the
converter output when long motor cables are used, are reduced.
The maximum permissible output frequency when a motor reac-
tor is used is 150 Hz.
Motor reactors are designed for the following maximum motor
cable lengths:
•
Shielded cables: 300 m (e.g. Protodur NYCWY)
•
Unshielded cables: 450 m (e.g. Protodur NYY)

L10
dv/dt filter plus Voltage Peak Limiter
dv/dt filters plus VPL (Voltage Peak Limiter) limit the voltage rate-
of-rise dv/dt to values < 500 V/
μ
s and the typical voltage peaks
to the following values in accordance with the limit value curve
according to IEC/TS 60034-17: 2006:
•
< 1000 V at
U

< 575 V
•
< 1250 V at 660 V <

The dv/dt filter plus VPL functionally consists of two components,
the dv/dt reactor and the voltage limiting network (VPL), which
limits voltage peaks and feeds the energy back to the DC link.
Depending on the converter output rating, option
L10
can be ac-
commodated in the converter cabinet unit or an additional cab-
inet of 400 mm or 600 mm width is required.
By using a dv/dt filter plus VPL, standard motors with standard
insulation and without insulated bearings can be used with sup-
ply voltages up to 690 V in converter operation.
dv/dt filters plus VPL are designed for the following maximum
motor cable lengths:
•
Shielded cables: 300 m (e.g. Protodur NYCWY)
•
Unshielded cables: 450 m (e.g. Protodur NYY)
For cable lengths < 100 m shielded or < 150 m unshielded, the
dv/dt filter compact plus VPL (option
L07
) can be advanta-
geously used.
The appropriate information in the SINAMICS Low Voltage
Engineering Manual should also be carefully observed.
