III. Configuration Description

Dual encoders full closed-loop

The main channel connects the motor's built-in encoder, while the secondary channel connects an optical encoder or an external encoder externally to cancel out mechanical transmission gaps and significantly improve positioning and repeat positioning accuracy.

SERCOS II bus

Primarily used for retrofitting of old equipment and replacing spare parts of existing production lines, compatible with the original bus architecture, and no need for overall line modification.

S1 basic safety

Equipped with basic safety protection logic, meeting the safety requirements of ordinary industrial equipment, not applicable to scenarios with STO or SIL high-level safety specifications.

Reduced hardware + pre-installed firmware

No additional expansion modules, simple and stable architecture; comes with its own firmware, convenient for on-site installation and debugging.

IV. Application Scenarios

Replacement of spare parts for old SERCOS II bus precision equipment, and overall machine renovation

CNC machines, precision inspection equipment, semiconductor equipment (dual encoder full closed-loop positioning)

Conventional automated production lines, with basic safety requirements, without high-level STO safety functions

Projects that pursue quick installation and use, simplifying on-site debugging
