Product Introduction
The PMAC2-PCI (603726-10C) is a PC-based motion control card used in machine tools, converting equipment, packaging, and precision positioning systems. It runs the motion program and servo loops, and drives the motor amplifiers through the attached motor interface.
The replacement risk is programmatic, not mechanical. A card that seats, powers up, and enumerates on the PCI bus can still be wrong if the firmware revision or the loaded PMAC program does not match the original. Verify the nameplate, the firmware version, and the project backup before ordering.
QA & Testing SOP
Identical for new original and surplus. No shortcuts.
- Inbound verification. Part number, revision, serial number, and firmware label photographed and matched against the customer’s PMAC project documentation. Mismatched revisions are quarantined.
- Physical inspection. PCI edge connector, pins, and board examined under magnification for rework, oxidation, or bent-pin damage.
- Bench power-up. Seated in a test chassis; PCI enumeration, startup sequence, and self-diagnostics logged.
- Functional exercise. Where the platform permits, axes exercised with a loaded motion program; servo response and encoder feedback verified against the OEM configuration.
- Anti-static packaging. Moisture-barrier bag, desiccant, ESD label. Signed test record packed with the unit.
Installation Pitfalls & Guide
❗ Firmware and program mismatch. A replacement card with a different firmware revision or an unloaded motion program will enumerate on the PCI bus and then fail during a positioning move. Load the validated program from the OEM backup and confirm the revision.
❗ Motor interface pairing. The PMAC2-PCI does not drive motors directly. Replacing the card without verifying the attached motor interface revision is a common cause of post-install axis faults.
❗ PCI slot and resource conflicts. Moving the card to a different slot can change IRQ and memory allocation, producing intermittent communication errors that look like card failure.
❗ Cabinet environment. Dust, humidity, or degraded ventilation will destroy the replacement on the same timeline as the original. Correct the enclosure condition during the outage.
Replacement sequence:
- Pre-install — Confirm safe machine state, apply lockout/tagout, photograph nameplate, slot position, and cable routing.
- Removal — De-energize the chassis fully, release retention, extract straight without stressing the edge connector.
- Install — Seat fully in the same slot, engage retention, reconnect motor and encoder cables against the photographed reference.
- Power-on test — Verify PCI enumeration, load firmware and motion program, home each axis, run a low-speed test move, then return to service.
Technical FAQ
Can I substitute a different PMAC2 PCI part number if the exact one is unavailable? Only after engineering review. Part number and revision differences can change axis support or firmware behavior, and a mismatch may pass enumeration yet fail during a positioning move.
Is hot swap supported? No. The card is not hot-swappable. Full system power-down is required before removal.
Why does the replacement card show an axis fault after install? Most often it is not the card. Check slot position and resource allocation, motor interface pairing, firmware revision, program load status, and encoder cable continuity.
What warranty applies? New original units carry standard coverage as stated on the quotation. Surplus units carry a shorter, disclosed term confirmed before payment.
Is the PMAC2-PCI still supported? The PMAC platform remains in Delta Tau’s portfolio, but individual part numbers move toward channel inventory over time. That makes revision, firmware, and lead-time confirmation more decisive than unit price on this part.
