The "Safe Torque Off" function is always active and cannot be deactivated.
During the booting process, the drive system is in the "STO" operating status;
i.e., the output stage has been switched off via two channels.
After the booting process, the safety function "Safe Torque Off" is active.
When the drive is switched from "operating mode" to "configuration mode" /
"parameterization mode", the functionality of the "Safe Torque Off" function is
maintained, i.e. according to the selection, the "Safe Torque Off" function
becomes active or not.
Step 1: Connecting and wiring the
"Safe Torque Off" function
The connection and wiring of the "Safe Torque Off" function depends on the
