The PWM Power Switch will supply DC power to the servo amplifiers when the signal POWERON/ is grounded. When this signal is connected to + 5 V it will remove power and connect the internal braking resistor to the servo amplifiers.
Note that the Logic Ground is connected to Motor Ground in the board.
