Base Body
The base body is the basis of the positioner. The V-417.xx6211E0
.
The base body comprises the following subassembly (subassemblies):
Drive
The drive of the positioner is a 3-phase magnetic linear motor. The linear motor transfers the
drive force to the motion platform directly and free of friction.
Reference Point Switch
The reference point switch is a sensor whose fixed position serves as the reference point for
incremental sensor signals.
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.
Incremental linear encoder
An incremental linear encoder is a sensor that measures the position of the motion platform
incremental to a known reference point. Optical linear encoders measure the actual position
directly. Therefore, errors in the drive, such as nonlinearity, backlash or elastic deformations
cannot influence the measurement of the position.
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.
