Allen-Bradley 1336-GM1 Drive Communication Board

Configured for Remote I/O network communication and SCANport data transfer in 1336 Adjustable drive platforms, the Allen-Bradley 1336-GM1 (1336-GM1 Internal Communication Board) provides direct physical/electrical execution.

Hardware Specifications

Proportional Control and Deterministic Network Integration

• Proportional Control Integration: Translates 8-word I/O image tables from the host Remote I/O scanner directly into drive command and velocity reference structures, executing deterministic speed adjustments across 1336 PLUS II, FORCE, REGEN, and SPIDER drives.
• Backplane Bus Communication Velocity: Communicates via the 14-pin internal SCANport connection to pass real-time drive diagnostics and operational states back to the network master without introducing scan latency.
• Firmware Flash Compatibility: Maintains hardware-level protocol alignment with standard Allen-Bradley Remote I/O scanners and PLC architectures via hardware DIP switch settings.

Frequently Asked Questions

Q: How is the 1336-GM1 module powered during operation?

A: The card derives its operating power directly from the host drive DC power supply through the internal 14-pin SCANport connection.

Q: What function does the 8-position DIP switch perform on the module?

A: The 8-position DIP switch configures the Remote I/O rack address, starting quarter, primary baud rate, and rack size settings for network communication.

Q: Can the 1336-GM1 card be installed into any option slot of a 1336 PLUS II drive?

A: The board must be mounted specifically to the host drive's internal SCANport connector interface as designated by the drive installation manual.

Field Installation Guidelines

• Power Down and Bus Discharge: Disconnect main AC supply voltage from the host drive and wait for internal high-voltage DC bus capacitors to discharge completely prior to opening drive covers.
• Physical Mounting: Align the card with the internal mounting posts on the drive SCANport interface, connect the 14-pin internal header, and secure all hardware.
• Remote I/O Wiring: Connect the 3-pin Remote I/O cable to the front terminal block, maintaining proper polarity for Blue, Clear, and Shield conductors.
• Grounding and Shielding: Terminate the cable shield braid to cabinet earth ground at the scanner end to prevent electrical noise from disrupting serial communications.
