IndraDrive Mi: Mixed operation of SD and L3

Hello community,

I am currently designing a decentralized drive line with a customer and would appreciate your technical feedback on our safety concept.

System Architecture: 1x XCU and 12x IndraDrive Mi (KSM02).

Master Communication: EtherCAT.

Safety Setup:

-          Drive 1 (First Axis): KSM02 with SafeMotion (SD) option, controlled via FSoE.

-          Drives 2 to 11: KSM02 with STO (L3) option .

-          Drive 12 (Last Axis): KSM02 with SafeMotion (SD) option, controlled via FSoE.

-           All Axis are on the same Safety Zone

Is this configuration possible?

Is it possible to use the digital outputs on connector X141 (X141.1 and X141.2) on the first SafeMotion axis (Drive 1 with SD) to select the "Safe Torque Off (STO)" signal for the L3 axes (Drives 2–11)?

Thanks for your feedback.

Daniel
