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.
