A high precision feedback device that gives position and velocity data. Resolution ranges from just a few hundred counts per revolution to over a million counts per revolution.

Alternating Current. Typical power source that comes 'out of the wall'. Single phase and three phase are standard. In the USA the standard values are 120VAC single phase and 208VAC three pha [..]

In the velocity loop, acceleration feedforward acts to inject additional torque/force to compensate for delays inherent during high rates of change in velocity.

For servo systems, any device (such as a motor) that outputs mechanical motion using electricity as the power source.

Ampere. The basic unit of electric current.

The strength of an electric current expressed in amperes.

Ampere. The basic unit of electric current.

In motion control this is the component that follows the command from a controller and provides power to the motor. In the strictest sense, amplifiers operate in current mode where the output current [..]
