● The DI/DO 9 to 11 can be used as high-speed inputs for measuring inputs or for external 
zero marks.
The assignment of the inputs is not fixed, and the special use is activated in the 
SIMOTION SCOUT engineering system.
● All 
four digital inputs/outputs can be used as freely addressable inputs or as homing inputs.
When parameterizing the DI/DOs as digital outputs, these can be used as freely addressable 
outputs. 
 
 
Note
Shielded cables are required when connecting measuring inputs or external zero marks for 
optimal noise immunity.

7.4.2.4 Power supply
Application
This interface is provided exclusively for connection of an external power supply.     
 
 
Note
When using external power supplies (e.g. SITOP), the ground potential must be connected 
with the protective ground terminal (PELV).
