dv/dt filter plus VPL (Voltage Peak Limiter) limit the voltage rate-of-rise dv/dt to values < 500 V/μs and the typical voltage peaks to the following values according to the limit value curve to IEC/TS 60034‑17: 2006:
< 1000 V at Uline < 575 V
Standard motors with standard insulation and without insulated bearings can be used for inverter operation if a dv/dt filter plus VPL is used.
The dv/dt filter plus VPL are designed for the following maximum motor cable lengths:
For shorter cable lengths (100 m shielded, 150 m unshielded) also refer to dv/dt filter compact plus VPL.
The maximum permissible cable length between the dv/dt filter and Power Module is 5 m.
