Allen-Bradley 150-F201NBD | SMC Flex Smart Motor Controller

Overview

The Allen-Bradley 150-F201NBD is part of the SMC Flex family of smart motor controllers. Designed for demanding industrial applications, it provides reliable soft starting and controlled stopping of three-phase motors. With advanced protection, programmable features, and multiple control modes, this controller enhances both performance and equipment longevity.

Electrical Ratings

The 150-F201NBD supports a line voltage range of 200–460 Volts AC, three-phase, at both 50 and 60 Hertz. It is rated for a maximum output current of 201 Amperes and delivers up to 150 horsepower at 460 Volts AC. Control voltage operates between 100 and 240 Volts AC, while total power efficiency is supported through solid-state circuitry and integrated SCR bypass technology.

Control Modes and Features

This motor controller includes multiple start and stop profiles, such as Soft Start, Full Voltage Start, Current Limit Start, Dual Ramp Start, Pump Start, and Accu-Stop. Additional modes include Smart Motor Braking, Selectable Kickstart, Preset Slow Speed, Coast-to-Rest, and Linear Speed Acceleration with tachometer feedback. The 150-F201NBD therefore supports nine start/stop modes and three distinct slow-speed modes.

Monitoring and Communications

The 150-F201NBD features an integrated keypad with a backlit LCD for configuration, monitoring, and troubleshooting. It also supports an optional 20-HIM-A module via its built-in DPI communication port. Metering functions include measurement of amps, volts, kilowatts, kilowatt-hours, megawatts, elapsed time, and power factor.

Protection and Diagnostics

The controller provides robust protection features, including overload, underload, line fault, power loss, undervoltage, overvoltage, excessive starts per hour, and phase reversal. It also monitors controller temperature, open gate faults, communication errors, stalls, and jams. These diagnostics ensure reliable operation in critical environments.

Mechanical and Compatibility Data

The 150-F201NBD is an open-type solid-state controller with a three-wire connection design. It is fully compatible with Delta wiring configurations and includes four programmable auxiliary contacts for signaling functions such as up-to-speed, fault, alarm, or network status.
