Connectable devices
The following devices can be connected to the PROFIBUS DP interfaces:
●
PG/PC
●
SIMATIC HMI devices
●
SIMATIC controllers with PROFIBUS DP interface
●
Distributed I/O
●
Teleservice adapter
●
Drive units with PROFIBUS DP interface (standard slaves)
Note
For remote diagnosis, a teleservice adapter can be connected to the PROFIBUS X21 or
X24 interface. A teleservice adapter can only be connected to one of the two interfaces.
The power supply for the teleservice adapter (terminals 2 and 7) can accept current loads
as high as 150 mA and is sustained short-circuit proof.
3.4
Encoder interface (HTL/TTL/SSI)
The HTL/TTL/SSI encoder interface is used to connect external encoders.

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 p400 and in the following parameters.
