Internal armature short-circuit with the "Safe Torque Off" function
The function "internal armature short-circuit" can be configured together with the "STO"
function.
The "STO" safety function has the higher priority when simultaneously selected. If the "STO"
function is initiated, then an activated "internal armature short-circuit" is disabled.
