62 Altivar 61 variable speed drives Output Power Options dV/dt output filters In applications where the impedance on either end of the motor cable run does not match, voltage pulses may be reflected back. As these reflected waves encounter other waves, their values add, causing high peak voltages. Voltage wave reflection and peak voltages increase with longer cable lengths, increased drive switching frequency, and faster voltage rise times, (dV/dt). When installed, dV/dt filters increase the time it takes the voltage to rise, slowing the pulse transitions, reducing dV/dt, reducing voltage peaks, and protecting motor and cable insulation.
