3.2.7 General instructions on measuring systems
Please note
Note that the positioning accuracy which can be reached
depends on the type of measuring system used.
The mechanical work path (possible slide path) of the
measuring system can be longer than the electrical work path
(usable stroke length of the measuring system).
If analogue measuring systems are used
(e.g. type MLO−POT−...), the following also applies:
In conjunction with the SPC200, an electrical reserve of
ţĂ0.3Ă% of the rated length is also required in both end
positions, see section 3.4.
Example:
ć Nominal length of the measuring system: 1000 [mm]
ć Permitted work path: 3...997 [mm]
Caution
If the slide of the measuring system leaves the permitted
work path, the SPC200 will generate an appropriate fault
message. In order to avoid these fault messages, limit the
positioning range so that the slide of the measuring sysĆ
tem is always within the permitted work path.
