5.4 Limit switch
5.4.1 Tools and accessories
– 1 set of hexagon socket wrenches
– 1 set of screw drivers
5.4.2 Preparatory measures
NOTE
Before the limit switches are set, the zero offset and the transfer position must be checked.
Check the zero offset (see section 5.2.3 "Checking and setting the zero offset").
5.4.3 Setting the limit switches
Move the feed axis into the transfer position (see section 4.2.4 "Checking the transfer positi-
ons").
Set the maximum position of the limit switch above its limit switch holder until there is a di-
stance of approximately 1 mm between the driver in the transfer position and the contact roller
of the limit switch.
Move the feed axis into the zero position (see section 5.2.3 "Checking and setting the zero
offset").
Set the minimum position of the limit switch above its limit switch holder until there is a distance
of approximately 1 mm between the driver in the zero position and the contact roller of the limit
switch (approximately 10 mm on tower 2).
Check the end positions of the feed axis (see section 5.3.2 "Checking and calibrating the end
positions").
