About 150-F201NBD

The 150-F201NBD is part of Allen-Bradley’s Bulletin 150 SMC Flex Smart Motor Controller line. It provides microprocessor controlled starting for Wye-Delta or 3-phase squirrel-cage induction motors. All Bulletin 150 controllers have a built-in SCR bypass/run contractor, CT on each phase, an LCD display, 4 programmable auxiliary contacts, keypad programming, and DPI communication. The 150-F201NBD has passed stringent compliance standards and it has certifications that include the EN/IEC 60947-4-2, the CE Mark in accordance with the EMC Directive and the Low Voltage Directive, the UL 508, and the cULus Listing. The Flex Smart Motor Controller offers various modes of operation. The first one is the soft start, which is the most common starting method for general applications. The motor starts at a specified torque setting. The output voltage to the motor increases during the acceleration ramp time. Another feature of the 150-F201NBD is the selectable kick-start. This start feature offers a boost during the startup to jump start loads that might need a pulse of high torque to start. Its purpose is to provide a current pulse for a specific timespan.

 

The 150-F201NBD also comes with a current limit start method. The operators can adjust the starting current as well as the current limit starting time by using this method. When the application requires varying loads, start times, and levels of starting torque, then the operators can choose a dual ramp start. It allows the operator to choose from 2 start profiles with different initial torque settings and ramp times. The 150-F201NBD also has a full voltage start option that is ideal for applications that require across-the-line starting. The smart motor controller can be programmed to provide a full voltage at the startup. With this setting, the system achieves the output voltage it needs in a quarter of a second. It also has a linear speed acceleration mode that maintains the acceleration of the motor at a constant rate. The users can install a tachometer on the motor to provide a feedback signal to the controller. Applications that require a slow speed at the start can benefit from the controller’s preset slow speed mode. The users can set it at low or high speed. The users can also program the 150-F201NBD for reverse operation. Lastly, there is a soft stop mode that is applicable to applications that need an extended stop time. The users can set the voltage ramp downtime between 0 seconds and 120 seconds. The load stops when the voltage reaches a set load torque that is higher than the rated motor torque.
