System Architecture & Signal Flow
The 1394C-SJT05-T-RL operates as a standalone servo controller receiving motion commands from an upstream PLC (PLC-5 or SLC 500) via the Remote I/O link. The module’s internal DSP executes real-time current, velocity, and position loops for each axis independently. Encoder feedback signals are processed at the module level, and fault status is reported back to the host PLC via the RIO data table. The shared DC bus allows multiple drive axes to exchange regenerative energy, with excess energy dissipated through an optional dynamic braking resistor.
Typical signal flow: Host PLC → Remote I/O Link → 1394C Controller → PWM Inverter → Servo Motor → Encoder Feedback → 1394C Controller (closed loop)

Technical FAQ
Q: Is the 1394C-SJT05-T-RL compatible with ControlLogix or CompactLogix platforms?
A: No. This module uses the legacy Remote I/O (RIO) protocol and is designed for PLC-5 and SLC 500 host controllers. For ControlLogix integration, a 1756-DHRIO bridge module is required.
Q: Can this module be used as a single-axis drive?
A: Yes. The 1394C-SJT05-T-RL supports 1 to 4 axes; unused axis slots remain inactive and do not affect system operation.
Q: What servo motors are compatible?
A: The module is designed for use with Allen-Bradley MPL, MPM, and 1326 series servo motors with incremental encoder feedback. Consult Rockwell publication 1394-UM001 for full motor compatibility tables.
Q: Is firmware upgrade support available?
A: Konmask can advise on firmware revision identification. Firmware updates for 1394C modules require Rockwell Automation DriveExplorer software and a 1203-GU6 DPI/SCANport interface.
Q: What is the typical lead time from stock?
A: In-stock units ship within 1–2 business days. Out-of-stock units: 2–6 weeks depending on sourcing channel. Contact us for real-time availability.
