5.1.2 Division marks
The number of increments of the connected speed sensor can be parameterized via
the parameter
Division marks speed sensor 2 494. The number of division marks of
the speed sensor is to be selected according to the speed range of the application.
The maximum number of division marks S
max
is defined by the limit frequency of f
max
=
300 kHz of the speed sensor inputs EM-ENC (track A) and EM-ENC (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
min
of the incremental speed sensor for a required minimum speed n
min
can be calculated from this requirement. The evaluation of four signal edges per mark
is firmly defined in the function of speed sensor 2.

5.1.3 Level
Via the parameter
Operation mode Level 495, the following operation modes can be
selected:
Operation mode Function
0 - push-pull
Push-pull signals (5 V) are evaluated
(according to specification RS-422A/RS-485).
2 - unipolar
Unipolar signals (10 V…24 V) at A+ and B+ are evalu-
ated.
