Allen-Bradley 1394C-AM07 AC Servo Controller Axis Module | Replacement, Equivalent & Selection Guide
The Allen-Bradley 1394C-AM07 is a dedicated axis module for the Rockwell Automation 1394 Series AC Multi-Axis Servo Controller system. Designed for high-precision motion control in industrial automation environments, it provides coordinated multi-axis servo drive capability within a shared DC bus architecture. This guide is intended to help engineers and procurement teams evaluate the 1394C-AM07 alongside its known replacements, functional equivalents, and cross-brand alternatives.
Selection Background
When sourcing a servo axis module, buyers frequently search for 1394C-AM07 replacement, 1394C-AM07 equivalent, or 1394C-AM07 substitute — either because the original unit is discontinued, lead times are extended, or budget constraints require a functional alternative. This page consolidates that research into a single reference, covering direct drop-in options, functional equivalents, and cross-brand alternatives, so you can make a confident selection decision.

Compatible Replacement & Equivalent Models
1. Direct Drop-in Replacements
These units share the same form factor, connector pinout, and firmware compatibility within the 1394 chassis:
- 1394C-AM07 (new or refurbished OEM unit) — identical specification, zero configuration change required
- 1394-AM07 — earlier revision; verify firmware revision compatibility with your 1394 controller before installation
2. Functional Equivalents
Same current rating and servo function within the Allen-Bradley ecosystem, but may require chassis or firmware adaptation:
- 2094-AM02 (Kinetix 6000 Axis Module, 7 A) — requires migration to Kinetix 6000 chassis; not a physical drop-in but functionally equivalent for new system designs
- 2094-AM02-S — Safe-off variant; adds STO (Safe Torque Off) capability
Note: Functional equivalents require system-level re-engineering. Consult Konmask engineering support before ordering.
3. Cross-Brand Alternatives
For applications where platform migration is acceptable:
- Siemens SIMODRIVE 611 / S120 — comparable multi-axis servo architecture; requires full drive and motor re-commissioning
- Yaskawa Sigma-7 Series — high-performance alternative for new machine designs; not compatible with 1394 chassis
- Mitsubishi MR-J4 Series — cross-brand substitute for greenfield projects
Cross-brand alternatives are not plug-and-play substitutes. Full system integration engineering is required.
Why Choose the Original Model
- Precision Guaranteed: Factory-calibrated current loop and velocity loop tuning matched to Rockwell Automation specifications
- Certified Compliance: UL and CE certifications maintained; third-party substitutes may void system-level certification
- Seamless Compatibility: Native backplane communication with 1394 controller — no gateway, no adapter, no firmware workaround
- Rockwell Technical Support: Full access to Rockwell Automation TechConnect support and firmware update channels
- Warranty Coverage: OEM warranty applicable; refurbished units from Konmask include Konmask quality warranty
- Reduced Commissioning Risk: Drop-in replacement eliminates re-tuning, re-wiring, and re-validation effort
Typical Applications
- Automotive Manufacturing: Robotic welding and assembly lines requiring coordinated multi-axis motion
- Packaging Machinery: High-speed pick-and-place and form-fill-seal equipment
- CNC Machine Tools: Multi-axis milling and turning centers with servo-driven axes
- Semiconductor Fabrication: Precision wafer handling and lithography stage control
- Printing & Converting: Web tension control and register servo systems
- Material Handling: Automated storage and retrieval systems (AS/RS) with coordinated servo drives
System Compatibility
The 1394C-AM07 is designed to operate within the following system components:
- 1394C-SJT22-T — 1394 System Power Module (22 kW), shared DC bus supply
- 1394-SR9 — 1394 Servo Controller (9-axis), system coordinator
- 1394-DIM — Digital Interface Module, for encoder feedback routing
- 1394-TBAM — Terminal Block Assembly Module, axis wiring interface
- 1326AB Series — Allen-Bradley AC servo motors, matched motor family
- 1394-CHASSIS — 1394 Modular Chassis, physical mounting and backplane
Selection Guide
Answer these three questions to confirm the 1394C-AM07 is the right choice for your application:
- Does your system use a 1394 Series chassis? If yes, the 1394C-AM07 is a direct drop-in. If no, a functional equivalent or cross-brand alternative may be required — contact Konmask for guidance.
- Is your continuous axis current requirement ≤ 7 A RMS? If your motor nameplate or drive sizing exceeds 7 A continuous, you will need a higher-current axis module (e.g., 1394C-AM15 at 15 A). Konmask can assist with sizing verification.
- Is this a replacement for a failed unit or a new system design? For direct replacement, the 1394C-AM07 OEM or refurbished unit is the lowest-risk option. For new designs, consider migrating to the Kinetix 6000 or Kinetix 5700 platform for long-term support.

Replacement & Compatibility FAQ
Q: Can I use the 1394C-AM07 as a direct replacement for a failed axis module in my existing 1394 system?
A: Yes. The 1394C-AM07 is a direct drop-in replacement for any 1394C-AM07 unit in a 1394 chassis. No firmware changes or re-wiring are required. Verify the revision level matches your controller firmware if you are replacing an early-revision unit.
Q: Is the 1394-AM07 (without the “C” suffix) compatible with / equivalent to the 1394C-AM07?
A: The 1394-AM07 and 1394C-AM07 are functionally similar but differ in revision and chassis compatibility. The “C” designation indicates a specific chassis form factor. Confirm your chassis type before substituting — contact Konmask if you are unsure.
Q: What is the best substitute for the 1394C-AM07 if I am designing a new machine?
A: For new machine designs, Rockwell Automation recommends migrating to the Kinetix 5700 or Kinetix 6000 platform, which offers longer product lifecycle support and enhanced safety features. The 2094-AM02 (Kinetix 6000, 7 A) is the closest functional equivalent in current rating. Konmask can assist with migration planning.
