Pulse/direction interface

Setpoint value specification with HTL level
Thanks to the pulse/direction interface, SINAMICS S110 can be used for simple positioning
tasks on a controller. Connection to the controller is via internal encoder interface X23 of the
CU305.
The controller gives the drive two signals: A pulse sequence with a pulse/pause ratio of
50:50 and a directional signal.
Table 7- 13
Type: 15-pin SUB D connector
The required settings for the pulse/direction interface need to be made in the STARTER.
Please refer to the SINAMICS S110 Function Manual for details.
Connection example
The image below shows an example of how to connect a pulse/direction interface with HTL
