Allen-Bradley 1394 Servo Drive Repair & Support
Allen-Bradley 1394 analog servo drive systems still run thousands of machines. With the platform discontinued and installations now 20+ years old, Star Automations supports repair of 1394 modules, sourcing of spares, and migration review toward current Kinetix platforms.
What is the 1394 system?
The Allen-Bradley 1394 is an analog servo drive system built around drive modules such as the 1394C-SJTxx series, 1394-AMxx axis modules, and GMC control modules, paired with 1326AB servo motors (a 1:1 pairing with the 1394 drive). It was widely used on Rockwell-based machines in the 1990s and 2000s and remains in service on many production lines.
Why demand exists now
- Rockwell Automation has discontinued the 1394C series, and its published migration direction is the Kinetix 5500 / 5700 platform (per an industrialmonitordirect.com analysis dated May 2026).
- Because the installed base is aging — user discussions document 1394 systems running 20+ years and developing intermittent faults (PLCTalk thread) — dedicated repair and replacement vendors cover 1394 modules, including GMC modules (e.g. magnaproducts.com, repairmode.com and NJT resources).
Typical fault context
Modules arrive for evaluation with intermittent faults, fault codes at startup or during motion, or failed axis modules. Each unit is assessed individually — Star Automations does not publish module-specific repairability claims.
Your routes with Star Automations
Repair path
Submit the module for per-unit technical evaluation. Send the exact module model from the nameplate (e.g. 1394C-SJT10-T, 1394-AM04) plus the fault code or behaviour.
Module sourcing
If a module cannot be repaired, Star Automations can search for used or surplus 1394 drive modules, axis modules, GMC modules and paired 1326AB motors. Availability is confirmed per request — no stock is claimed on this page.
Migration review
Rockwell’s direction is Kinetix 5500 / 5700. A 1394-to-Kinetix move is an engineering project (wiring, axis mapping, motion programming) — Star Automations supports the review rather than treating it as a drop-in swap.
What to send for an evaluation
A clear photo of the module nameplate showing the exact catalog number (1394C-xxxx / 1394-AMxx / GMC), the fault code or symptom, and the machine make/model if known. Photos can be sent through WhatsApp below.
Allen-Bradley 1394 — answers
Is the 1394 servo drive discontinued?
Yes. Rockwell Automation has discontinued the 1394C series and its published migration direction is the Kinetix 5500 / 5700 platform.
Can you repair my 1394 module?
Repair is evaluated per unit. Send the module model and fault details and Star Automations confirms whether repair is practical; no module-specific repairability is assumed.
Can you source a used 1394C module or 1326AB motor?
Sourcing is confirmed per request. Send the exact catalog numbers and Star Automations will search its sourcing network; no stock is claimed on this page.
Should we migrate to Kinetix?
Migration to Kinetix 5500 / 5700 is an engineering project. Star Automations can review your application and support the decision — it is not treated as a drop-in sale.
What information do you need?
The exact module catalog number from the nameplate, the fault code or behaviour, and your machine make/model. A nameplate photo via WhatsApp is the fastest start.
