The Allen-Bradley 150-F317NBD is a SMC Flex Smart Motor controller. This controller is a solid-state device, typically used in industrial applications. This device is more commonly referred to as a Soft-Starter by most plant personnel. It is paired to a 3-Phase motor to implement protective start-up and shutdown features as well as lower energy consumption.

Motor protection and energy consumption is implemented by the control methods supported by the 150-F317NBD such as Soft Start, Full Voltage Start, Smart Motor Braking, Current Limit Start, Dual Ramp Start, Accu-Stop, Selectable Kickstart, Pump Start, Slow Speed with Braking, Coast-to-rest, Preset Slow Speed, Linear Speed Acceleration (Tachometer required), Soft Stop and Pump Stop. This controller is ideally used in compressor, chillers, pumps, conveyors and crushers.

The 150-F317NBD comes with an open type enclosure. It has a line Voltage requirement of 200-460VAC, 3-Phase, 50 and 60 Hz and control Voltage of 100-240V AC (5-480 A units). It delivers maximum continuous output current of 317 Amperes and output power of 250 HP at 460VAC rated voltage with an open type enclosure. This controller also comes with an integrated backlit LCD display which aids in programming and monitoring of the controller operation.

The 150-F317NBD also comes with integrated input and output channels such as Four fully programmable contacts which can be assigned for normal/up-to-speed/fault/alarm/network (N.O./N.C.) indication or external bypass (N.O. only) status. This motor controller is also capable of displaying current, volts, kW, kWh, MW, MWH, elapsed time, power factor, and motor thermal capacity usage.

This controller may be configured through a computer workstation via the Connected Components Workbench (CCW).

The Allen-Bradley 150-F317NBD smart motor controller shows great diversity when it comes to motor start modes. The most commonly used is the soft start method, in which the user sets the motor to an initial torque setting (user-adjustable in a 0 to 90% range of fixed rotor torque), then increases output voltage gradually during the acceleration ramp time (0 to 30 seconds adjustable). This module’s kickstart option can also be applied with soft start. There is also a current limit (limiting maximum starting current) option, a dual ramp start option, a full voltage start (in 0.25 seconds) option, a soft stop option, a preset slow speed option, and a linear speed mode option. This SMC is equipped with an integral LCD display and programmable keyboard, for fast and user-friendly programming and configuration. An optional Bulletin 20-HMI LCD (Human-Module Interface) is offered as an alternative for programming purposes. This unit’s parameters are reasonably structured and can be viewed or edited over this module. The 150-F317NBD has the following dimensions: 600.00 x 289.97 x 276.50 millimeters (23.62 x 11.42 x 10.88 inches). The weight of the 150-F317NBD is approximately 45.8 kilograms (101 pounds) and its temperature rating lies between -5 and 50 degrees Celsius.
