The RGH22B measuring system from Renishaw (grid division = 20 µm)
only has connections which are compatible to Heidenhain from serial
number G69289 onwards. For earlier sensor heads, the zero mark can-
not be evaluated.
As the reference mark for the Renishaw RGH22B has a direction–de-
pendent position, with control cables BID and DIR, the encoder must
be parameterized, so that the reference mark is only output in one di-
rection.
The direction (positive/negative) depends on the geometrical arrange-
ment at the machine and the reference point approach direction.

The counting direction of the measuring system is positive if the sensor
head moves relative to the gold band in the cable outlet direction.

Note
If the sensor head is mechanically connected to the primary section,
the cable outlet direction must be different. Otherwise, invert the actual
value!

Note
The positive counting direction of the linear measuring system from the
Zeiss company should be determined just like the measuring system
RGH22B from Renishaw (refer to Fig. 4-19).
