The smallest impulse lengths that can be used to move the actua-
tor are determined during the initialization process. They are sepa-
rately determined for the "Up" and "Down" directions and displayed
here. Display in ms.
These two parameters can be set for special applications.

The value for the "25.PAUTP" parameter is factory-set to 28 ms.
This value is not changed during an initialization process. Display
in ms.
For applications with high stiction (slipstick), adjusting this parame-
ter improves the control quality.
This parameter can be set for special applications.

26.DBUP: 0.1 ... 10.0
27.DBDN: -01. ... 10.0
In this parameter, you can read the deadbands of the controller in
the "Up" and "Down" directions. Display in percent. The values
correspond either to the manually configured value of the
"'34.DEBA' Deadband of closed-loop controller (Page 163)" param-
eter or to the value automatically adapted by the device if "DEBA"
was set to "Auto".
