Axis is positioned to the right of the Bero. The homing operation is
started by bit 4 in the control word.
Behavior of MASTERDRIVES MC with F01
The axis traverses under speed control at homing approach velocity v
[MD7] towards the Bero. When the Bero responds, the axis decelerates
down to homing creep velocity v
rotation. When the Bero falling edge 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.
Behavior of MASTERDRIVES without F01
The axis moves under position control towards the Bero at the values
stored in U006 (homing acceleration) and U873.01 (homing speed).
When the Bero responds, the axis changes its direction of rotation and
continues moving at the same velocity in the opposite direction. When
the Bero falling edge appears, the axis is decelerated to a standstill with
the value from U006. It does not retrace the braking path traveled
during the braking operation. It activates "Homing Attained" in the
status word via bit ARFD.

Axis is positioned on the Bero installed as a homing switch. The
homing operation is started by bit 4 in the control word.
