Technical Features
3.7.1
Linear Encoder (Sensor)
Some of the Q-521 models are equipped with an optical linear encoder. For the encoder
resolution, refer to the table in the "Specifications" section (p. 49).
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.
3.7.2
Reference Point Switch
The Q-521 models equipped with a sensor have an optical reference point switch.
The commands that use the reference signal are described in the user manual of the controller
and/or in the corresponding software manuals.
3.7.3
ID Chip
Q-521 models with sensor contain an ID chip in the connector.
The following data is stored as parameters on the ID chip:
Information on the linear stage: Type, serial number, date of manufacture, version of
the hardware
Settings for the sensor: Interpolation rate, corrections of hysteresis as well as of phase
and offset, gain values
When switched on or rebooted, controllers from PI read the data from the ID chip.
For more information on the ID chip recognition, see the manual of the controller used.
