Digital frequency input/output (encoder simulation)
The digital frequency coupling of ECSxS/P/A axis modules basically is effected as a
master−slave connection via the interface X8. This interface can either be used as a digital
frequency input or as a digital frequency output (e. g. for encoder simulation)
(configuration via C0491).
Features
X8 as digital frequency input
X8 as digital frequency output
l
Input frequency: 0 ... 200 kHz
l
Current consumption: max. 6 mA per channel
l
Two−track with inverse 5 V signals and zero track
l
Possible input signals:
– incremental encoder with two 5 V complementary
signals (TTL encoders) offset by 90°
l
The function of the inputs signals can be set via
C0427.
l
Output frequency: 0 ... 200 kHz
l
Permissible current loading: max. 20 mA per
channel
l
Two−track with inverse 5 V signals (RS422)
l
The function of the output signals can be set via
C0540.
