Axis is homed without a Bero. The homing operation is started by bit
4 in the control word.
The axis traverses under speed control at homing creep velocity v
[MD6] in a negative direction. When the zero pulse appears, the axis is
decelerated down to standstill under speed control. It retraces the
deceleration path traveled as a result of the braking operation by
executing a position-controlled return motion (positioning) towards the
zero pulse. The axis then activates "Homing Attained" in the status
word via bit ARFD.
