 Inductive filter cards add inductance to the motor/drive system. To ensure current loop stability, a minimum inductance is essential for the proper operation of a PWM drive. For example, if the drive datasheet calls for a minimum of 250uH of inductance and your motor only has 25uH, then the addition of the BFC15030 will ensure proper operation. The total inductance for the motor and filter card will be 25uH + 300uH = 325uH.
Inductive filter cards are also used to reduce PWM switching noise that occurs with high power supply voltages (>250VDC) and long cable runs (>10m)
