How is AIN connected internally in MAC00-B1 ?

 

 

 

On the B1 module there is both an AIN on the power connector and on the 9 pole connector.
Are they connected together and if so, how should the connections be made to avoid ground loops?

The analogue ground and P- are connected together.
You cannot use the zero search input and analogue input at the same time.
Use I/O ground together with +/-10V servo loop applications and
use P- as ground when you use 24V sensors for zero search purposes.
