Allen-Bradley 1336F-MCB-SP1C – Main Control Board | 1336 FORCE AC Drive Platform
Engineering Background
The Allen-Bradley 1336 FORCE series represents Rockwell Automation’s high-performance vector AC drive platform, widely deployed across heavy industrial sectors including oil & gas, mining, metals, and large-scale manufacturing. The 1336F-MCB-SP1C is the main control board (MCB) spare part for this drive family — the central processing and signal coordination assembly that governs all closed-loop vector control, I/O interfacing, and communication functions within the drive chassis.
Product Positioning
Sourced for maintenance engineers and procurement teams managing legacy 1336 FORCE installations, this board provides a direct OEM-equivalent replacement path without requiring full drive replacement. Konmask.com stocks this component to support unplanned downtime recovery and scheduled preventive maintenance programs across global industrial facilities.

- Documented Traceability: Each unit supplied with part number verification and condition documentation
System Architecture & Signal Flow
Within the 1336 FORCE drive architecture, the MCB (Main Control Board) sits at the center of the control hierarchy:
- Inputs: Speed reference (analog/digital), encoder feedback (optional), I/O command signals from PLC/DCS via SCANport or hardwired terminals
- Processing: DSP executes real-time flux vector algorithm — computing slip frequency, torque current, and flux current vectors at high update rates
- Outputs: PWM gate firing signals to the power structure (IGBT/transistor base drive board); fault relay outputs; analog output signals for process monitoring
- Communication: DPI/SCANport interface to peripheral devices (HIM, communication adapters, I/O expanders)
- Diagnostics: Onboard fault logging accessible via HIM or DriveExplorer/DriveExecutive software
Sourcing & Quality Verification
- Source Channels: Authorized surplus distributors, decommissioned OEM equipment, and certified repair facilities
- Incoming Inspection: Visual inspection for physical damage, component integrity check, and part number/revision verification against Rockwell Automation documentation
- Functional Testing: Available on request — bench-tested units verified against known-good drive chassis prior to shipment
- Packaging: ESD-safe anti-static bag, foam-padded carton; suitable for international air freight

Technical FAQ
Q: Is the 1336F-MCB-SP1C compatible with all horsepower ratings of the 1336 FORCE drive?
A: The MCB-SP1C variant is designed for specific frame sizes within the 1336F family. Please confirm your drive’s full catalog number (including voltage and HP suffix) to ensure revision compatibility. Contact us for cross-reference assistance.
Q: Will replacing the MCB erase my drive parameters?
A: Parameters are stored in the drive’s memory module or HIM, not on the MCB itself in most 1336F configurations. However, we recommend backing up parameters via DriveExplorer software before any board replacement as a best practice.
Q: Can I use a refurbished MCB in a safety-critical application?
A: Refurbished units are bench-tested and functionally verified. For SIL-rated or safety-critical applications, consult your site safety engineer and review Rockwell Automation’s guidelines for spare part qualification.
Q: Do you provide installation support?
A: Yes. Our technical team can provide step-by-step board replacement guidance and commissioning checklists. Remote support via email or video call is available.
Q: What is the difference between SP1C and other MCB variants (SP1A, SP1B)?
A: Suffix letters denote hardware revision levels. Each revision may include component updates or firmware changes. Always match the replacement board revision to your existing drive’s MCB revision for guaranteed compatibility.
