5.11 Connecting an external encoder
Connecting the connecting cable
Use only shielded cables to connect an external encoder to the encoder interface (X23). The
shielding must be connected with the metallic or metallized connector housing.
We recommend that bipolar encoders are used. When using unipolar encoders, the unused
negative track signals can either be connected or connected to ground. This results in
different switching thresholds. See section Encoder interface (HTL/TTL/SSI) (Page 45).
The pre-assembled connecting cables offer optimal noise immunity as well as sufficiently
measured cross-sections for the supply voltage of the external encoder.
The connecting cables are available in various lengths, see
Procedure for connecting encoders
To connect an external encoder (HTL, TTL or SSI encoder), proceed as follows:
1. Connect the connecting cable to the encoder.
2. Plug the D-Sub connector (15-pin) to the socket X23.
3. Lock the connector using the finger screws.
NOTICE
Always ensure that you can operate the connected encoder on a 24 V power supply (e.g.
HTL encoder). Operating a 5 V encoder on a 24 V supply may cause its electronic
components to be destroyed. This setting can be set in the expert list of the drive in
parameter p0400 and in the following parameters.
