Dv/Dt Filter Compact Plus Voltage Peak Limiter - Siemens SINAMICS S120 Manual

Options

9.24 dv/dt filter compact plus Voltage Peak Limiter

9.24 dv/dt filter compact plus Voltage Peak Limiter
Availability of option
This option is available for the following S120 Cabinet Modules:
● Motor Modules
Description
The dv/dt filter compact plus Voltage Peak Limiter comprises two components: the dv/dt
reactor and the voltage-limiting network (Voltage Peak Limiter), which cuts off the voltage
peaks and feeds back the energy into the DC link. The dv/dt filter compact plus Voltage Peak
Limiter is designed for use with motors for which the voltage strength of the insulation
system is unknown or insufficient.
dv/dt filters compact plus Voltage Peak Limiters limit the voltage rate of rise dv/dt to values <
1600 V/µs - and the typical voltage peaks to the following values according to limit value
curve A acc. to IEC 60034-25:2007:
● < 1150 V at U
● < 1400 V at 660 V < U
The dv/dt filter compact plus Voltage Peak Limiter is installed in an additional cabinet with a
width of 600 mm that is located on the right-hand side of the Motor Module.
Note
Operation of standard motors with standard insulation and without insulated bearing is
possible on SINAMICS converters up to line supply voltages of 690 V.
Note
Cabinet width
The width of the Motor Module cabinet is reduced by 200 mm. The additional components
are installed in a supplementary cabinet, 600 mm wide. The motor cables also connected in
this supplementary cabinet.
Restrictions
The following constraints should be noted when a dv/dt filter compact plus Voltage Peak
Limiter is used:
● The output frequency is limited to no more than 150 Hz.
● Maximum permissible motor cable lengths:
– Shielded cables: max. 100 m (e.g. Protodur NYCWY)
– Unshielded cables: max. 150 m (e.g. Protodur NYY)
