Yes you are using non intelligent Drives, sometimes referred to as dumb drives, these can be easier to set up sometimes

It works just the same, Yaskawa Mitsubishi Etc there Encoders all feed back to the Servo Drives, then the Servo Drive is connected to the Galil or what ever motion control card/ hardware you are using, they use just the same Velocity/Torque mode,the prefered method for cnc control
