Your display unit will accept all HEIDENHAIN linear encoders with
sinusoidal output signals (11 to 16 µApp) and distance-coded or single
reference marks.

Encoder monitoring
Your display unit features a monitoring system for checking the
amplitude and frequency of the encoder signals. If it detects a faulty
signal, one of the following error messages will be generated:
SIGNAL X
FRQ. ERR. X
Encoder monitoring can be activated with parameter 45.
If you are using linear encoders with distance-coded reference marks,
the encoder monitoring system also checks whether the spacing of
the reference marks as defined in parameter P43 is the same as the
actual spacing on the scales. If it is not, the following error message
will be generated:
ERR. REF. X
