4.8.2 Two Incremental Encoders
It is possible to connect two 2-track incremental encoders where channel 1 (A, B) supports TTL and HTL, while channel 2 (Z, D) only
supports TTL.

Illustration 6: Wiring Configuration for 2 Incremental Encoders
1 Incremental encoder, 2 differential tracks (TTL, HTL)
2
Incremental encoder, 2 differential tracks (only TTL on Z and D).
The incremental encoder connected to channels Z and D may require separate supply.
4.8.3 Resolver
With a resolver, the actual position is set to the absolute value within one resolver pole pair based on the analog value of the sine
and cosine signals.
With a 2-pole resolver, this corresponds to the absolute position within one resolver revolution.

Setting
Select [5] 2 track Incremental A,B + 2 track incremental Z,D.
Set the appropriate supply voltage for the connected encoders. If the power requirement exceeds the
maximum power of the internal supply, the second 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.
