The Allen-Bradley/Rockwell Automation 1336F-BRF150-AA-EN-HASB-L4 drive is a 480 Volts AC motor controller. The controller has an English manual and an open type enclosure. The 1336F-BRF150-AA-EN-HASB-L4 features a TTL contact on its control option. This type of control option is easy to use when it is interfacing the 1336F-BRF150-AA-EN-HASB-L4 with different types of circuits. Also, a TTL contact supports simple and complex logic functions. Additionally, a TTL contact has tolerable noise margins and predictable noise levels. Other advantages of a transistor-transistor logic contact (TTL) is its immunity from electromagnetic discharges. However, note that a TTL contact has a high current consumption. The high current consumption is capable of interfering with the drive’s normal operation.

The Allen-Bradley 1336F-BRF150-AA-EN-HASB-L4 drive does not have a human-machine interface module and its slot has a snap-in cradle/blank plate for mounting an optional interface. The controller is part of the Allen-Bradley 1336 PLUS 2 family of controllers. Controllers in this family do not support the torque follower load sharing technique. This is because the 1336F-BRF150-AA-EN-HASB-L4 and other controllers in the same family cannot operate as a torque regulator, making a total torque follower configuration impossible. However, for load-sharing functions, the 1336F-BRF150-AA-EN-HASB-L4, like other 1336 PLUS 2 controllers, can use the droop load sharing technique. To use this technique, the speed control parameter has to be set to ‘droop’. Other parameters used to prepare the 1336F-BRF150-AA-EN-HASB-L4 for the droop load sharing technique is the slip compensation gain which adjusts the recovery rate for load changes and the ‘slip@FLA’ parameter which is used to set the amount of frequency that will be subtracted from the speed reference at a full load current.
