dv/dt filter compact plus Voltage Peak Limiter (Option L07)

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 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:
● < 1400 V at 660 V < U
Restrictions
The following constraints should be noted when a dv/dt filter compact plus Voltage Peak
Limiter is deployed:
● The output frequency is limited to no more than 150 Hz.
● Maximum permissible motor cable lengths:
– Shielded cable: max. 100 m
– Unshielded cable: max. 150 m
NOTICE
Damage to the dv/dt filter compact by exceeding the maximum output frequency
The maximum permissible output frequency when a dv/dt filter compact is used is 150 Hz.
The dv/dt filter compact can be damaged if the output frequency is exceeded.
• Operate the dv/dt filter compact with a maximum output frequency of 150 Hz.
NOTICE
Damage to the dv/dt filter compact during continuous operation with low output frequencies
Uninterrupted duty at an output frequency less than 10 Hz can result in thermal overload
and destroy the dv/dt filter.
• When using a dv/dt filter compact plus voltage peak limiter do not operate the drive
• You may operate the drive for a maximum load duration of 5 minutes at an output
