monitoring, set the parameter to 'On'. The sub-parameter is dis‐
played. Appropriately set the sub-parameter.
The current value is displayed in Diagnostic value '26.DBUP - Dead‐
band UP' / '27.DBDN - Deadband DOWN' (Page 263). The position‐
er triggers a message if the current value exceeds the threshold.

cent. Set the threshold in a range from '0.1' to '2.9'.
The threshold 3 fault message is displayed when the current dead‐
band exceeds the threshold during the test. The procedure to acti‐
vate and display this error message is described in the 'XDIAG' pa‐
