6.3.6 Using the digital interface module with the digital 2-axis SIRIUS II
position indicator (for technical information, see chapter 12 in the
MINI-X product catalogue).
Storage temperature of the position indicator:
-40 °C to + 70 °C
Operating temperature of the position indicator:
0 °C to 45 °C in relative humidity between 15% and 95% without condensation.
Digital signal input to the position indicator must be used in order to make use of
the full resolution of the interface module in the position indicator. This has a
maximum permissible input frequency of 1 MHz (based on one channel, e.g. the A
signal). Consequently, a count rate around 4 times higher occurs during 4-edge
evaluation. This limits the maximum possible travelling speed to 0.4 m/s for a
resolution of 0.1 µm.
