Make sure the target wheel maintains the permitted air gap tolerances in
the rotational speed range used. Take into account any high spots.
Make sure the target wheel does not reach the critical rotational speed.
If the target wheel is not arranged symmetrically to the measuring surface, measuring
errors may occur. To ensure correct function of the MiniCODER, it must be exactly
adjusted.
 Align the MiniCODER symmetrically in relation to the measuring scale, the lines of
symmetry must match (
→ page 37 ). Keep to the limits stated.
3.9 EMC instructions
To improve the electromagnetic environment, please observe the following installation
instructions:
 Only use connectors with a metal housing or a housing made of metallised plastic,
as well as screened cables.
 Connect the screen, if foreseen in the screening concept, to the connector housing.

Connect the screens using large surface area connections.
 Keep all unscreened cables as short as possible.

Design the earth connections with a large cross-section (e.g. using a low inductance
earth strap or flat conductor) and keep them short.

If there are potential differences between machine earth connections and electronic
earth connections, ensure no equalising currents can flow over the cable screen.
For this purpose, e.g. lay an equipotential bonding cable with a large cross-section
or use cable with separate double screening.
In case of cables with separate double screening, only connect the screens at one
end.
