The axis traverses under speed control at homing approach velocity v
A
[MD7] in the direction of the positive limit switch (reversal cam). When
the cam responds, the axis its direction of rotation and travels towards
the Bero. When the Bero responds, the axis decelerates down to
homing creep velocity v
R
[MD6]. When it exits the Bero in the negative
direction, it searches for the next zero pulse of the position encoder.
When the zero pulse is found, the axis is braked to a 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.

The axis is positioned to the left of the Bero. The homing operation
is started by bit 4 in the control word.

The axis is positioned to the right of the Bero. The homing operation
is started by bit 4 in the control word.
The axis traverses under speed control at homing approach velocity v
A
[MD7] towards the positive limit switch (reversal cam). When the cam
responds, the axis changes its direction of rotation and travels towards
the Bero. When the Bero responds, the axis decelerates down to
homing creep velocity v
R
[MD6] and reverses its direction of rotation.
When it exits the Bero in the positive direction, it searches for the next
zero pulse of the position encoder. When the zero pulse is found, the
axis is braked to a 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.
