【C】●CCW (Counter Clock Wise)
Counterclockwise motor rotation from the view point of the axis.
●Closed-loop Method
A control method in which the information of position and speed from the encoder is to be fed back to the controller.
●Coupling
Shaft coupling. A mechanical component to connect shafts. In the case of electric actuators, coupling is used to connect the motor and the screw playing the role like a floating joint.
●Critical Speed
The speed of a slider (ball screw rotations) which causes resonance of a ball screw. The physical limit of available speed.
●CW (Clock Wise)
Clockwise motor rotation from the viewpoint of the axis.
●Cycle Time
Time required to complete one process.
