●S-shaped Curve Driving Method
A method in which acceleration is reduced at the beginning and end of the accelerating range, and increased in the middle. Reducing the impact of acceleration and deceleration, this method is effective when smooth movement is required.
Selective Compliance Assembly Robot Arm. A robot arm that has compliance in the horizontal direction and high stiffness in the vertical direction.
A control method in which every step of control is advanced one by one according to the already-indicated orders or procedures.
●Servo Free (Servo Off)
The state in which the power supply for the motor is cut off.
The slider can be moved freely.
●Servo Lock (Servo On)
The state in which the power supply for the motor is switched on. The servo mechanism maintains its position even though an external force is applied as long as the position command remains unchanged.
A general term to describe motors used in the servo mechanism. Usually the motor has high response characteristic with a position finder such as an encoder and follows a targeted value by using the feedback control. The position control, speed control and thrust control, etc. are possible.
The uncontrolled state in a servo mechanism.
The controlled state in a servo mechanism.
Time elapsed after a speed command becomes zero until the actuator stops in positioning operation.
A cable with its core wire covered by electrostatic shieldaluminum tape, braided wire, etc. Not easily affected by noise.
To limit the operating range to the software.
●Step Motor (Stepper Motor)
A motor which does angular positioning proportional to input pulse signals by using an open-loop control (or a motor activated by synchronization to the frequency of the current). Relatively easy to control movements.
