dv/dt filter (option L10)
The drive generates pulses at the drive output which have a negative impact on the motor
insulation. The dv/dt filter is used to limit the voltage gradient to max. 1 kV/µs. At the same
time, the dv/dt filter is used to limit the capacitive recharging currents of the motor cables, and
therefore protects the motor insulation system. The dv/dt filter is integrated in the power unit.
