Illustration 7: Wiring Configuration for Incremental Encoder, 3 Single Tracks (TTL, HTL)
1 Incremental encoder
5.5.2 Two Incremental Encoders
It is possible to connect two 2-track incremental encoders where channel 1 (A, B) supports TTL and HTL, and channel 2 (Z, D) sup-
ports only TTL.

Setting
Select [5] 2 track Incremental A,B + 2 track incremental Z,D.
Set the appropriate supply voltage. If the power requirement exceeds the maximum power of the
internal supply, the 2nd encoder may require external supply.
Voltage can be up to 24 V. Setting the voltage too high can damage the connected encoder.
Set the resolution of the encoder connected to A and B in pulses per revolution.
Set the resolution of the encoder connected to Z and D in pulses per revolution.
