Tab. 66: X4A connection description for differential TTL and differential HTL incremental encoders (HTL via HT6 adapter)
Information
Using an HT6 adapter for level conversion from HTL signals to TTL signals, it is also possible to connect a differential HTL
incremental encoder to terminal X4. Note that, with an external power supply, the maximum level of 20 V
DC
for the HTL
signals may not be exceeded.
