Base Body
The base body is the basis of the positioner. The L-412.xx9232
is mounted onto a surface via
the base body (p. 13)
.
The base body comprises the following subassembly (subassemblies):
Drive screw
The drive screw converts the rotary motion of the drive to linear motion of the motion
platform.
Limit switches
The limit switches are sensors at each end of the travel range that enable the electronics to
abort motion in order to prevent the motion platform from colliding with the mechanical
hard stop.
4.4.2
Drive
The drive generates the torque required for the dynamics of the motion platform.
The drive comprises the following subassembly (subassemblies):
Motor
The motor generates the torque required for the dynamics of the motion platform.
Rotary encoder
The rotary encoder measures the motor shaft's angle of rotation. This signal can be used by
suitable electronics for commutating the motor and for calculating the position of the motion
platform after a reference move .
4.4.3
Purge Air System
The purge air system protects the drive and guides of the L-412.xx9232 against surrounding
dust.
The purge air system comprises the following subassembly (subassemblies):
