2.3 Fitting electric axes
Refer to the following documentation when fitting the electric
axis:
Operating instructions for the axis used.
Instructions for the components used.
Warning
If an axis is fitted in a sloping or vertical position, the work
load may fall down and injure somebody.
· Use the motor unit preferably with self−locking or self−
braking spindle drives.
· Check whether additional external safety measures
against spindle nut fracture are necessary (e.g. toothed
latches or moving bolts).
You can then avoid the working mass sliding down if there
is a sudden power failure.
Make sure that:
· the drive is fitted securely and is free of distortion
· the work space, in which the axis moves, is of sufficient
size for operation with a work load
· the work load does not collide with any component of the
drive when the slide moves into the end position.
· Make sure that you observe the maximum permitted va
lues of the following variables: the basis point for forces
and torques is the centre of the shaft (L3 see Tab.2/1).
