In parameter
S-0-0173, Marker position A
the position of the
reference mark is also stored during the execution of the
"C0600 Drive-controlled homing procedure command"
(S-0-0148). This position, however, refers to the "old"
coordinate system (before switching the coordinate system
when executing the homing procedure).

Measuring Wheel Mode/Hybrid Position Control
Brief Description
The measuring wheel mode is used for material feed axes, e.g. in sheet-
metal machining. For direct measurement of the infeed of moved material
a rotary encoder that is detecting the infeed length is driven via a
measuring wheel with frictionally engaged contact to the material surface.
The position control loop is closed via motor encoder and measuring
wheel encoder, possible slip between motor and material does not cause
incorrect measured values of material length.
Note:
The measuring wheel mode may only be activated when
contact has been established between measuring wheel and
material surface.

Hardware Requirements
The measuring wheel encoder is an optional (external) encoder that is
connected according to the connection diagram contained in the
documentation "Project Planning Manual for Control Section".
