The SAFE TORQUE OFF function may be used in a safety-related application in
preventing the drive from generating torque in the motor to a high level of
integrity. The system designer is responsible for ensuring that the complete
system is safe and designed correctly according to the relevant safety
standards. If the SAFE TORQUE OFF function is not required, these terminals
are used for enabling the drive.
