Product Introduction & Supply Chain Strategy
The GE Fanuc IC693DSM302-BF is a 2-axis Motion Mate digital servo module designed for Series 90-30 PLCs. It offloads complex positioning, velocity profiling, electronic gearing, and touch-probe registration tasks from the central CPU, driving precise motion via digital servo commands or ±10V analog outputs.
Procuring this specialized motion card as New Surplus provides vital supply-chain protection for critical automated positioning lines. Sourcing factory-fresh, uninstalled original inventory eliminates the severe risks of high-frequency signal drift, encoder input channel failure, and thermal processing degradation common in second-hand cards extracted from harsh industrial environments.

Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
- Execute strict Lock-Out/Tag-Out (LOTO) protocols on the main CPU rack power supply and field servo drive power rails.
- Wear a grounded anti-static wrist strap before handling the IC693DSM302-BF to protect sensitive high-speed processing components from ESD damage.
- Record or photograph existing cable connections (I/O, drive interface, and encoder feedback cables) connected to the high-density front connectors.
Stage 2: Removal
- De-energize the PLC rack and unbolt the front interface cables from the module ports.
- Squeeze the release latches at the top and bottom of the DSM302 card.
- Slide the module straight outward from the baseplate slot to prevent twisting or bending backplane pins.
Stage 3: Installation (Clone & Seat)
- Align the rear card-edge guide of the replacement IC693DSM302-BF with the designated I/O slot in the Series 90-30 baseplate.
- Press firmly on the top and bottom face of the module until both retaining latches click into place.
- Reattach and secure all front panel interface cables to the designated Axis 1 and Axis 2 connectors.
Stage 4: Power-On & Testing
- Reapply power to the baseplate and observe the module diagnostic LEDs.
- Confirm the module “MODULE OK” LED lights solid green, and status LEDs indicate correct axis enable states without servo fault codes.
- Connect via VersaPro or Proficy Machine Edition, verify parameter table transfers (accel/decel limits, counts per user unit), and execute low-speed jog commands to verify encoder feedback direction.
Firmware/Software Versions & Upgrade Notes
- Revision Compatibility: The “-BF” suffix indicates the hardware and onboard firmware manufacturing revision. Revision BF is fully backward-compatible with older revisions (e.g., AA through BE) of the IC693DSM302.
- Software Configuration: Configured using Motion Developer, VersaPro, or Proficy Machine Edition (PME). Axis configuration parameters, motion block sequences, and tuning constants are loaded directly from the PLC software project file.
- CPU & Firmware Dependencies: Ensure the host Series 90-30 CPU firmware supports Motion Mate modules (CPU331 or higher running firmware version 6.0 or later). Replacing a lower-density motion module (such as a 1-axis DSM301) with a 2-axis DSM302 requires updating the PLC hardware configuration and %I/%Q memory allocations to accommodate the second axis.
Frequently Asked Questions (FAQ)
Is this IC693DSM302-BF module brand new or pulled from a used machine?
This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability.
Why is buying New Surplus critical for motion control cards like the -BF?
Motion cards perform real-time position calculations and continuous high-speed encoder processing. Refurbished or pulled motion cards frequently exhibit micro-cracks in solder joints, degraded optical isolation on probe inputs, and failing digital-to-analog convertors that cause position drift or erratic motor runaway. Investing in New Surplus guarantees original factory timing precision and full component operational life.
What quality control procedures are conducted before shipment?
ry undergoes a complete inspection protocol. This includes anti-counterfeit serial verification, backplane connector pin alignment checks, insulation continuity testing, and live power-on test rack verification to confirm communication handshake and axis diagnostic integrity.
What is the primary difference between the IC693DSM301 and the ?
The IC693DSM301 controls 1 digital servo axis, whereas the controls up to 2 independent or coordinated servo axes from a single module slot.
he handle analog servo drives in addition to digital servos?
Yes. The module supports both digital servo command communications (for GE Fanuc digital servo systems) and standard ±10V analog speed/torque command outputs for interfacing with third-party analog servo drives.
What warranty coverage comes with this New Surplus motion module?
This module includes a full 1-year functional warranty. If any operational anomaly or hardware defect occurs during normal operation within 12 months, we will immediately provide a replacement unit from our active buffer stock.
