Ascertaining the output signals per revolution
For angle encoders with interfaces of the type TTL you can use a teach sequence
to ascertain the exact quantity of output signals per revolution.
Tap Settings in the main menu
Tap
Axes
Tap the desired axis designation or Not defined , if applicable
If applicable, select the name of the axis from the Axis name
drop-down list
Tap
Encoder
From the Encoder model drop-down list, select Angle
encoder
For Display mode select the - ∞ ... ∞ option
Tap Reference marks
Select one of the following options from the
Reference mark
drop-down list:
None : There is no reference mark
One
: The encoder has one reference mark
In order to switch to the previous axis, tap Back
To start the teach sequence, tap Start
The teach sequence is started and the wizard is displayed
Follow the instructions of the wizard
The number of output signals determined during the teach
sequence is transferred to the
Output signals per revolution
field
The ascertained quantity of output signals remains stored if you select a
different display mode after the teach sequence.

7.6.6 Performing error compensation
Mechanical influences such as guideway error, tilting in the end positions,
mounting surface tolerances, or poor mounting (Abbe error) can cause measuring
errors. With error compensation, the unit can automatically compensate for
systematic measuring errors during measuring point acquisition. Through the
comparison of nominal and actual values, one or more compensation factors can
be defined and applied during subsequent measurements.
A distinction is made between the following methods:
Configuring error compensation for individual axes
Linear error compensation (LEC): The compensation factor is calculated based
on the specified length of a calibration standard (nominal length) and the actual
distance traversed (actual length). The compensation factor is applied linearly to
the entire measuring range.
Segmented linear error compensation (SLEC): The axis is divided into multiple
segments with the help of a maximum of 200 supporting points. A distinct
compensation factor is defined and applied for every segment.
