dv/dt filter plus VPL (Voltage Peak Limiter) limit the voltage rate-of-rise dv/dt to values < 500 V/?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_line < 575 V

< 1250 V at 660 V < U_line < 690 V

Standard motors with standard insulation and without insulated bearings with a supply voltage of up to 690 V can be used for converter operation if a dv/dt filter plus VPL is used.

dv/dt filters plus VPL are designed for the following maximum motor cable lengths:

• Shielded cables: 300 m (984 ft) (e.g. Protodur NYCWY)
• Unshielded cables: 450 m (1476 ft) (e.g. Protodur NYY)

For shorter cable lengths (100 m (328 ft) shielded, 150 m (492 ft) unshielded), see also dv/dt filter compact plus VPL.

Notice:

The maximum permissible cable length between the dv/dt filter plus VPL and the Power Module/Motor Module is 5 m (16.4 ft).
