Parameters for setting the speed and direction of rotation:

Unlike an angular positioning control servo motor, a rotation servomotor (also called improperly servo 360 °) equally uses a PWM control signal, but the pulse duration determines the speed and direction of rotation (continuous ) and not the angular positioning in the following manner:

• Pulse width Pw from 1000us to 1500US, Vcc = 4.8V
  The rotation is counterclockwise typically with a speed that the maximum value of 0.22s / 60 ° (45 revolutions / minute) to Pw = 1000us is reduced, with the increase of Pw, until the stall (stop) to Pw = 1500US.
• Pulse width Pw from 1500US to 2000uS, Vcc = 4.8V
  The rotation is typically clockwise sense with a speed that stall for Pw = 1500US is increased, with the increase of Pw, up to the maximum value of 0.22s / 60 ° (45 rpm / minute) to Pw = 2000uS

On a side of the actuator body is a hole that allows to act on a trimmer that allows to calibrate the value Pw required for the pulse duration to get the stalemate.
