4.3.1
Base Body
The base body is the basis of the positioner. The L-505.021212
.
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.
Reference Switch
The reference 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.
Position sensor
The position sensor is an incremental sensor: It measures the position of the motion
platform relative to a known reference point. Optical linear encoders measure the actual
position directly (direct position measuring). Therefore, errors in the drive, such as
nonlinearity, backlash or elastic deformations cannot influence the measurement of the
position.
4.3.2
Drive Connector
The electrical connection to the electronics is established via the drive
The drive connector transmits the signals for the drive as well as the sensor signals of the
L-505.021212.
The drive connector comprises the following subassembly or subassemblies:
ID Chip
Information on the L-505.021212 (e.g., type, serial number, date of manufacture, hardware
version) is stored in parameters on the ID chip. Electronics that support the ID chip evaluate
the data from the ID chip and offer the corresponding positioner type from the positioner
database automatically for selection when starting with the PC software from PI.
For more information on ID chip recognition, see the manual for the electronics.
4.4
Suitable Electronics
The L-505.021212 must be connected to suitable electronics that supply the necessary
voltage for operating and if required, to evaluate the sensor and limit switch signals. The
following electronics are suitable:
