accidentally be put into action.
This does not apply to drives with the special “Safe Stop” feature in accordance with EN 954-1 CAT 3 or with
the “Safe Torque Off” feature in accordance with EN 61800-5-2.
This feature can be achieved with the item C 1-Series by integrating the module FSM 2.0 – STO for example.
Initial operation must be carried out with idle motors, to prevent mechanical damages for example due to the
wrong direction of rotation.
Electronic devices are never fail-safe. It is the user’s responsibility, in the case an electrical device fails, to
make sure the system is transferred into a secure state.
The servo positioning controller and in particular the brake resistor, externally or internally, can assume high
temperatures, which may cause serious burns.
