These functions are part of the standard scope of the drive and can be used without
requiring an additional license. These functions are always available. These functions do
not place any special requirements on the encoder used.

Safe Torque Off is a safety function that prevents the drive from restarting
unexpectedly in accordance with EN- 60204-1, Section 5.4.
