Encoder connection – Single-ended
Figure 15. HTL type encoder connection (open source) using single-ended inputs
NOTE! Grounding is to be connected only at the AC drive to avoid circulating current in the shield.
Isolate shield at the encoder.
It is recommended to use double shielded cable for encoder connection.
