5.3.3 Carrying out reference travel
Warning
Danger of injury.
Electric axes can move suddenly with high force and at
high speed. Collisions can lead to serious injury to human
beings and damage to components.
·
Make sure that nobody can gain access to the operating
range of the axis or of other connected actuators and
that no objects lie in the path of the axis while the
system is still connected to a power supply.
The drive moves during reference travel at first at the preset
search speed v_rp corresponding to the selected referencing
method up to the mechanical fixed stop (or reference switch)
and when the signal has been evaluated, takes up the posi
tion as reference point (Fig.5/1
1
).
The drive then moves at speed v_zp to the axis zero point
(Fig.5/1

).
