5.2.2 Setting the homing parameter
Caution
Damage to components
The slide may only move against the fixed stop if the per-
mitted impact energy is not exceeded. The permitted value
can be found in the manual for your positioning axis.
Impact energy = 0.5 x mass x speed

For the protection of the mechanical components:
• Reduce the speed at which homing run is carried out.
The speed can be specified at 0 % to 50 % of the rated
speed depending on the specific application.
• If necessary, limit the motor current during homing run
with the FCT software. The motor current can be speci-
fied with 1 to 200 % of the rated motor current depend-
ing on the specific application (see FCT/PlugIn help
MTR-DCI).
Caution
If the homing method is changed, the axis zero point offset
is reset to zero. Any settings implemented for the software
end positions and the target positions in the positioning
record table are retained. Note that these values refer to
the previous axis zero point.
• Always carry out a homing run after changing the refer-
encing method.
• Then teach the offset of the axis zero point.
If the axis zero point is modified:
• Teach the software end positions and the target posi-
tions again.
