The digital inputs EM-S2IND and EM-S3IND of the EM-IO-03 expansion module can be
set via the parameter
sponding operation mode for the evaluation of a unipolar 24V two-channel speed sen-
sor (incremental speed sensor).

The number of increments of the connected speed sensor can be adjusted via the

speed sensor is to be selected according to the speed range of the application.
The maximum number of division marks S
150 kHz of the digital inputs EM-S2IND (track A) and EM-S3IND (track B).
To ensure a good true running of the drive mechanism, a sensor signal must be
evaluated at least every 2 ms (signal frequency f = 500 Hz). The minimum number of
division marks S
can be calculated from this requirement. The evaluation of four signal edges per mark
is firmly defined in the function of speed sensor 2.
