Technical Features
3.6.1
Linear Encoder (Sensor)
The Q-632 is equipped with an optical linear encoder. Refer to the table in the "Specifications"
section (p. 37) for the encoder resolution.
Optical linear encoders measure the actual position directly (direct metrology). Therefore,
errors occurring in the drivetrain such as nonlinearity, backlash or elastic deformation, cannot
influence the measurement of the position.
3.6.2
Reference Point Switch
The Q-632 also has an optical reference switch.
The commands that use the reference signal are described in the user manual for the controller
and/or in the corresponding software manuals.
3.6.3
ID Chip
The Q-632 has an ID chip in the connector.
The following data is stored as parameters on the ID chip:
Information on the rotation stage: Type, serial number, date of manufacturer, hardware
version
Settings for the sensor: Interpolation rate, corrections to hysteresis, phase and offset,
gain values
When switched on or rebooted, controllers from PI read the data from the ID chip.
For more information on ID chip detection, see the manual for the controller.
