Hi ! Grittings of day..
During installation of PowerFlex Digital DC Drive we face a problem with HMI rpm indication if we cmd of 100 rpm motor rotates but with negative polarity showes on hmi (-100)
we change Armature dc o/p voltage cables ,motor direction change but problem as it is
we observed that tacho o/p voltage provides negative supply if we change wire it gives undervoltage fault F4
