Setpoint value specification: Sensor signal with TTL level
This sections shows an example of how to connect bipolar TTL encoders to the
pulse/direction interface of Control Unit CU305. Connection to the controller supports
setpoint value specification via A track and B track.
Table 7- 14
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.
