63 Presentation, references Variable speed drives Altivar Process ATV900: Output filters Option: dv/dt filters Presentation Altivar Process drives with supply voltage of 200...240 V and 380...480 V operate with the following maximum motor cable lengths: 150 m/ 492 ft for shielded cables and 300 m/984 ft for unshielded cables. For supply voltage of 500...690 V maximum motor cable lengths are: 10 m/ 32 ft for shielded cables and 20 m/ 65 ft for unshielded cables. To limit the impact of dv/dt and overvoltages in the motor, it is recommended, for cables longer than 50 m/ 164 ft , that you check the motor insulation type and add an output filter if necessary. For further information, please consult the An Improved Approach for Connecting VSD and Electric Motors White Paper available on our website www.schneider-electric.com. Output filters are used to limit dv/dt at the motor terminals to 500 V/s maximum for supply voltages up to 480 V, to 750 V/s maximum for supply voltage of 500 V and to 1000 V/s maximum for supply voltage of 690 V. Output filters are designed to limit overvoltages at the motor terminals to less than: b 800 V with a shielded cable 0 to 50 m ( 0 to 164 ft) long, with a 400 V supply voltage b 1,000 V with a shielded cable 50 to 150 m ( 164 to 492 ft ) long, with a 400 V supply voltage b 1,500 V with a shielded cable 150 to 300 m ( 492 to 984 ft ) long, with a 400 V supply voltage (up to 500 m ( 1,640 ft ) with an unshielded cable) b 1,300 V with 500 V supply voltage, cable length depending on the dv/dt filter combination b 1,600 V with 690 V supply voltage, cable length depending on the dv/dt filter combination The performance of dv/dt filters will be affected if the maximum cable lengths are exceeded. For an application with several motors connected in parallel, the cable length must include all cabling. If a cable longer than that recommended is used, the dv/dt filters may overheat. The switching frequency must be under 8 kHz. dv/dt output filters For drives Maximum length of motor cable Degree of protection In (3) Reference Weight Maximum switching frequency (1) Shielded cable (2) kHz m/ ft IP A kg/ lb Three-phase supply voltage: 200...240 V ATV930U07M3 4 300/ 984 20 6 VW3A5301 11.000/ 24.251 ATV930U15M3...U30M3 4 300/ 984 20 15 VW3A5302 12.000/ 26.455 ATV930U40M3 4 300/ 984 20 25 VW3A5303 12.000/ 26.455 ATV930U55M3...D11M3 4 300/ 984 20 50 VW3A5304 18.000/ 39.683 ATV930D15M3...D22M3 4 300/ 984 20 95 VW3A5305 19.000/ 41.888 ATV930D30M3...D45M3 ATV930D30M3C...D45M3C 2.5 300/ 984 00 180 VW3A5306 22.000/ 48.502 ATV930D55M3C...D75M3C 2.5 300/ 984 00 305 VW3A5307 40.000/ 88.185 (1) The filters are designed to operate in a switching frequency range of between 2 and 8 kHz. (2) Values given depend on the nominal switching frequency of the drive. This frequency depends on the drive rating. These cable lengths are given as examples only as they can vary depending on the application. They correspond to motors conforming to IEC 6034-25 and NEMA MG1/31.2006. (3) Nominal filter current.
