7.6 Shape of the rotation speed output signal

In the factory settings, two 90_ phase-offset speed signals (5 V symmetrical,
complementary RS422 signals) are available. You can double the pulse count
set in each case by moving switch S6 to the "On" position. Pin 3 then outputs
the direction of rotation as a static direction of rotation signal (pin 3=+5 V,
pin 7=0 V opposite pin 8), if the shaft turns in the direction of the arrow. At a
–1
rotation speed of 0 min (=rpm (revs per minute)), the direction of rotation si-
gnal has the last measured value.
