1.What is “Servo” ?
At the beginning,the word “servo” comes from the Latin word “servus”
acts according to his master’s instructions and works faithfully and quickly.
To put it simply, servos conduct follow-up control to a target position and speed.
They are good at moving quickly to a target position therefore adapt to a wide range of high-speed.
2.What can servo do?
Torque control –a current of the motor can control torque.
Speed control – Speed can change in response to a speed reference voltage.
a speed reference input control rotation speed of a motor.
A position reference decides Rotation angle (position) and rotation speed of a motor
When a motor stops, an electrical brake (servo clamp)
is applying to try to save position of the motor.
