III. Configuration Highlights

Dual encoder closed loop

Motor encoder provides coarse feedback for speed / position， load side absolute value encoder provides fine feedback， effectively eliminating transmission gap， significantly improving positioning and synchronization accuracy， suitable for precise processes.

PROFIBUS bus

Industrial universal bus， stable networking， seamless integration with Siemens PLC system， convenient for line automation integration.

SIL2 safety motion

Not only basic STO safety power-off， but also supports safety speed limit， safety direction， safety stop and other functions， meeting EU mechanical safety standards， suitable for human-machine interaction equipment.

No additional expansion modules， hardware is streamlined， focusing on dual encoders + bus + safety core functions.

IV. Application Scenarios

High-end CNC machines， precision feed axes / main shaft (full closed-loop positioning)

Shearing machines， following shearing， multi-axis synchronization， electronic cams， etc. high-precision synchronous equipment

Automated production lines in automotive manufacturing， etc. with mechanical safety compliance requirements

Precision automation equipment using Siemens PROFIBUS architecture， load side requires external encoder.
