The PTO embedded function can provide 2 different functions:
PTO The PTO (Pulse Train Output) implements digital technology that provides precise positioning for open loop control of motor drives.
PWM The PWM (Pulse Width Modulation) function generates a programmable square wave signal on a dedicated output with adjustable duty cycle and frequency.
