What is the difference between velocity mode motion and a velocity mode amplifier?
Velocity mode motion: Motion in a given direction (positive or negative) at a given velocity with no target position specified. The motor will continue to move until it is commanded to stop. Velocity mode amplifier: As it relates to motion control, an amplifier is an electronic device that, based on an external command signal (typically from a motion controller), provides current to the windings of a motor, which causes the motor to move. In addition to simply moving a motor based on an external command signal, a Velocity Mode amplifier also incorporates an internal feedback circuit that is used to tightly control the velocity of the motor.
