The Allen-Bradley Bulletin SMC Flex 150-F970NBE is a smart motor controller that acts as a microprocessor for a 3-phase standard squirrel cage induction motor or a Wye-Delta (6-lead) motor. It gives 7 standard modes of operation within a single controller for maximum application flexibility. This microprocessor is best-suited for controlling 3-phase squirrel cage induction motors that have a 1-1250 A range rating and that have integrated pump control and braking control options. The role of the pump control is to decrease power surges when the centrifugal pump is starting and stopping. This is achieved by accelerating and decelerating the squirrel cage motor smoothly. The braking control makes use of the 150-F970NBE microprocessor’s smart motor braking, accu-stop, and slow speed with braking options to slow down and stop.

 

The 150-F970NBE Smart Motor Controller’s other convenient features include electronic motor control overload protection and CT on each phase with 4 programmable auxiliary contacts. It comes with an LCD screen and DPI communication. The SMC Flex controller is available for motors rated at 1-1250 A, and at 200-480V AC, 200-600V AC, or at 230-690V AC, at a frequency of 50-60 Hz. In addition to motors, the 150-F970NBE SMC Flex controller can be used to control resistive loads. The Allen-Bradley SMC Flex 150-F970NBE Smart Motor Controller’s variety of operating modes include the soft start, the selectable kickstart. The current limit start, the dual ramp start, the full voltage start, the linear speed acceleration, the preset slow speed, and the soft stop.
