HEIDENHAIN PWM 20 - Manual (Page 76)

November 2014 Software description 77
Tolerances of the
incremental
status display Error display = "Red LED", if
 Amplitude too small: typical 0.20 Vpp (possible as of 0.25 Vpp)
 Amplitude too large: typical 1.30 Vpp (possible as of 1.25 Vpp)
 Frequency exceeded: > 2.0 MHz possible
5.3.3 Display encoder memory
Absolute HEIDENHAIN encoders with EnDat interface feature an internal encoder configuration
memory. The layout of the configuration memory and the meaning of the individual data words
are described in the interface specification entitled "EnDat Interface: Bidirectional synchronous
serial interface for position encoders."
This specification is available from HEIDENHAIN as a separate document.
Therefore, this manual does not provide explanations of the individual memory areas and data
words.

Click the function "Display encoder memory".
The encoder configuration window is activated.
Note
The threshold of the incremental status display is not identical with the bar display (red bars).
The red lines on the scaling of the bar display represent the tolerances of the general
specifications of the output signals (sales literature); the incremental status display
corresponds to the functional limit of the encoder!
