Machine zero modes with a home switch which is activated in the middle of the
travel range and can be deactivated to both sides.
The assignment of the direction reversal switches (see page 132) can be
changed.
Function Reversal via Current threshold
If no direction reversal switches are available, the reversal of direction can also be
performed during the machine zero run via the function "direction reversal via Cur-
rent threshold"
Here the drive runs towards the mechanical limit mounted at the end of the travel
range.
When the settable Current threshold is reached, the drive is braked and changes
the travel direction.
Caution!
Wrong settings can cause hazard for man and machine.
It is therefore essential to respect the following:
Choose a low machine zero speed.
Set the machine zero acceleration to a high value, so that the drive changes di-
rection quickly, the value must, however, not be so high that the limit threshold is
already reached by accelerating or decelerating (without mechanical limitation).
The mechanical limitation as well as the load drain must be set so that they can
absorb the resulting kinetic energy.
