●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.
