Product Overview
The Allen-Bradley 1336F-MCB-SP1K is a main control board (MCB) designed for the 1336 PLUS II series of adjustable frequency AC drives. As the central processing unit of the drive, the 1336F-MCB-SP1K executes all control algorithms, manages I/O signal processing, stores drive parameters in non-volatile memory, and coordinates communication between the power stage, operator interface, and external control systems. This board serves as the “brain” of the 1336F drive platform, handling everything from motor control calculations to fault diagnostics.
The 1336F-MCB-SP1K is specifically intended for Frame A drives within the 1336 PLUS II product line, with one board required per drive for proper operation. The SP1K designation indicates a particular hardware revision within the MCB family, and this board should not be interchanged with other suffix versions such as SP1I, SP1J, SP1L, or SP1M without verifying compatibility. The “-A” variant (1336F-MCB-SP1K-A) represents a specific revision level of this board, typically associated with the 1336 FORCE series and certain Frame F configurations.
For maintenance and repair operations, the 1336F-MCB-SP1K is a critical spare component. When a 1336 PLUS II drive experiences control-related faults or fails to initialize properly, the main control board is often the root cause. Replacing the 1336F-MCB-SP1K with a genuine Allen-Bradley unit restores the drive‘s original control logic, parameter storage, and communication capabilities, returning the system to full operational status.

Main Features and Advantages
Central Control Architecture for 1336 PLUS II Drives: The 1336F-MCB-SP1K functions as the primary intelligence of the 1336F drive platform, executing all motor control algorithms and managing real-time signal processing. It coordinates data exchange between the power stage, I/O modules, and optional communication cards through the drive backplane, ensuring synchronized operation across all subsystems.
Non-Volatile Parameter Storage: All drive configuration parameters, application settings, and fault history are stored in the board‘s non-volatile memory. This design allows technicians to back up settings from a working 1336F-MCB-SP1K and restore them to a replacement unit, dramatically reducing commissioning time after board replacement.
Direct Replacement for Failed MCB Assemblies: When a 1336F drive exhibits control faults, initialization failures, or persistent diagnostic errors pointing to the main control board, the 1336F-MCB-SP1K provides a drop-in replacement solution. The board is pre-tested and packaged in anti-static material to prevent damage during shipping and handling.
SP1K Version Identification: The SP1K suffix distinguishes this board from other 1336F MCB variants. Engineers must verify the exact suffix on the failed board before ordering, as mixing different MCB revisions can cause communication errors or parameter incompatibility within the drive.
Frame A Compatibility: The 1336F-MCB-SP1K is specifically configured for Frame A 1336F drives. This frame designation relates to the physical size and power rating of the drive, ensuring the board’s firmware and hardware interface match the connected power components.
