Application Scenarios

• Rotary Packaging Multi-Axis Indexing: This 10kW system module coordinates multiple servo axes on rotary filling and capping machines. The 1394-SJT10-C-RL synchronizes turret rotation, product transfer and tool actuation, maintaining precise timing for high-speed continuous production.
• Metal Forming Press Servo Control: Installed on mechanical servo press equipment, the unit manages ram motion plus feed and eject axes. Shared DC bus allows regenerative energy from one axis to be reused by other axes, reducing energy waste and braking resistor load.
• CNC Cutting Machine Multi-Axis Control: The module runs coordinated X/Y/Z servo axes for legacy cutting machinery. GML programming enables complex contouring moves, and Remote I/O connectivity links motion commands and machine safety interlocks to a PLC-5 host controller.

Key Product Notes

This GMC system module works with 1394-AMxx axis modules and 1326AB servo motors. The RL variant supports Remote I/O connection to PLC-5, while the C version provides analog command interfaces. Allen‑Bradley discontinued this motion control platform, so spare inventory supports maintenance of legacy multi-axis automation systems. Proper cabinet ventilation is required for continuous duty; shielded power and resolver cables must be used to avoid EMI-induced position jitter.
