Note:
If the value of parameter
P-0-0241, Actual pos. smoothing
time constant for hybrid pos. control
is "0", the actual
position value of the motor encoder is ignored and only the
actual position value of the measuring wheel encoder is used
for position control!
The mechanical arrangement of the measuring wheel encoder in the
mechanical drive system is illustrated in the figure below:

Arrangement of the measuring wheel encoder in the mechanical
drive system
The measuring wheel mode can only be used in position-controlled
operating modes (position control with cyclic command value input, drive-
internal interpolation etc.). But it is possible to switch to non-position-
controlled operating modes when the measuring wheel mode has been
activated or to activate the measuring wheel mode already in these
operating modes.
Activating the measuring wheel mode clears a possibly existing position
data reference to the axis for both encoders. In measuring wheel mode
the axis can only be moved in a relative way, the control master itself has
to establish the position data reference to the material to be infed!
