Operation without encoder

During the operation without encoder the generated pulses of the terminal are supplied as actual positions to the CNC internal position controller. The velocity command values, calculated by the position controller, are supplied to the stepping motor terminal, and causes the movement of the stepping motor.

Because the drive is operated in a pseudo position control loop, the parameterization of the stepping motor in the axis parameter list is done by analogy with the parameterization of a drive with +/- 10V interface. Also, here the use of the velocity pre-control is possible (see also chapter 1.7.1).
