7 Incremental interface
For dimension downstream electronics it shall be ensured that it is cor-
rectly dimensioned for the set edge distance or counting frequency!
It should be noted that pulses with the widths of the set edge distance
may occur with sensor idleness (due to the internal interpolation proce-
dure).
In parallel with the SN3-interface, the LD version outputs speed-propor-
tional incremental signals which have the differential form in accordance
with RS422.
The incremental signals shall be terminated by means of terminating
resistors with 120 ... 150 ohm (see
Fig. 2
).
Signal sequence
With the sensor being moved in the cable outlet direction, signal B will be
lagging in relation to signal A (A before B).
