001 on when cnt. value f ref. value
010 on when cnt. value F ref. value
011 pulse when cnt. value = ref. value
Sensor parameters (byte 1)
Signal evaluation
(A B)
00
A pulse and direction
In this mode input B can control
up and down counting in count
mode. In measurement mode
input B can receive a signal for the
rotational direction.
01 single-evaluation rotary sensor
Only Count mode: 10 double-evaluation rotary sensor
11 fourfold-evaluation rotary sensor
Sensor and input filter
An input filter at inputs A,B and DI can suppress high-frequency
interference and thus increase the accuracy of the counting.
The limit frequency can be adapted to the application:
20 kHz or 200 kHz.
