NOTe:
The safety function STO (Safe Torque OFF) is not required for the ServoOne
supply unit, as no motors are connected. To be able to start the supply unit, a
jumper must be placed between X4/14 and X4/22.
If this jumper is forgotten, there is a flashing point on the device display. The
safety function STO is used for ServoOne DC axis controllers.
