1394C-SJT05-D AC Driver  

Product Details Introduction

1394C-SJT05-D AC Driver (Servo System Module)

1394C-SJT05-D is a Rockwell Allen Bradley 1394C series 5kW modular servo drive system module used for multi axis high-precision motion control, supporting SERCOS fiber optic communication and GMC integrated architecture.

Product positioning: 1394C series 5kW servo system module, belonging to the core unit of multi axis motion control.

Input specifications: Three phase 324-528V AC, 50/60Hz, input current 6.5A.

Bus output: 380V input corresponds to 530V DC, 460V input corresponds to 680V DC.

Power output: continuous 4/5kW, peak 28kW.

Current output: continuous 7.36A, peak 15.0A.

Architecture features: Modular design, single rack can expand up to 4 axes, saving wiring and space.

Communication method: Standard SERCOS fiber ring network, supporting high-speed multi axis synchronous control.

Control mode: Supports speed/torque/position closed-loop, compatible with analog and digital settings.

Feedback support: Compatible with differential AB orthogonal encoder (up to 4MHz), supports external full closed-loop feedback.

Protection functions: multiple protections for overcurrent, overvoltage, undervoltage, overheating, encoder failure, and thermal overload.

Diagnostic tool: onboard LED status light, built-in digital fault and current/temperature monitoring.

Interface configuration: SCANPort, DI/DO, analog, encoder, and motor power interfaces are complete.

Application scenarios: high-precision multi axis equipment such as machine tools, semiconductors, packaging, printing, robots, etc.

Product status: The original factory has ceased production, and the market mainly consists of second-hand, refurbished, and repair spare parts.

Alternative solution: Upgrade to Kinetix 5500/6500 series servo drives, compatible with new motors and controllers.

In summary, 1394C-SJT05-D is the core module of the 1394C series 5kW servo system, known for its modularity, high-speed communication, and multi axis synchronization. It is a key spare part for existing precision equipment, and faults often manifest as communication abnormalities, no output, and overcurrent alarms. It is recommended to replace the entire board or upgrade the system.
