Default Settings and Operation /

Safe Torque Off Operation


ConveyLinx-Ai2/Ai3 controllers comply with:

EN ISO 13850 – Safety of Machinery – Emergency Stop Function – Principles for Design
EN ISO 13850:2015 (see also IEC 60204-1:2016)
ISO 13849-1:2023 – Safety of Machinery — Safety-related Parts of Control Systems

In compliance with EN ISO 13850, when ConveyLinx-Ai2/Ai3 controllers and their power and network installations are configured as described, the controllers meet:

Stop category 0 – Safe Torque Off (STO)
Performance Level – PL c

Compliance with EN ISO 13850 can be achieved by disconnecting the power to the ConveyLinx-Ai2/Ai3

By disconnecting the utility power source to the DC power supply feeding the motor power (MDR+) of the ConveyLinx-Ai2/Ai3 controllers, the compliant STO state is achieved as illustrated.
