Dynamic braking question
Thanks Waross for the reply. Let me ask you this...Whereas when with a dc method of dynamic braking, when the db contactor drops out, disabling the drives output from powering the drive and the combination of the now closed db contact in series with the db resistor also flows through the...- 2217116

Dynamic braking question
Is dynamic braking really "dynamic braking" with a vfd? I know that with a dc motor, the method of dynamic braking using a db contactor and a db resistor across the armature gives true dymic braking. However, with a vfd for instance when a three phase motor regenerates and causes the dc bus to...- 2217116
