Due to the inertia of the motor, it is not possible to move evenly at a velocity close to “0”. To avoid jerking of the motor, a minimum velocity (start/stop velocity) is defined. When the pulse interface is activated, motion is initially performed at start/stop velocity. From there, the motor is accelerated to the specified velocity. Shortly before the end position, the motor is decelerated until start/stop velocity is reached. Then the pulse interface will be deactivated. Figure 2-8
