When SVON signal is turned ON after applying power to the LECA6 controller, the actuator moved about

Servo motor (24VDC) type actuators make a movement to check the Z-phase of the motor when the servo is first time powered. As this Z-phase signal is a signal sent once every time the motor was switched on, the motor rotates about 1 to 2 complete turns.
〔For example, LEFS25AA is an actuator with a lead of 12mm, it can move about 12-24mm.〕
