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.

In this parameter, you can read the deadbands of the controller in
the 'Up' and 'Down' directions. Display in percent. The values corre‐
spond either to the manually configured value of the '34.DEBA'
Deadband of closed-loop controller (Page 154) parameter or to the
value automatically adapted by the device if 'DEBA' was set to 'Auto'.
0.1 ... 100.0
The slow step zone is the zone of the closed-loop controller in which
control signals are issued in a pulsed manner. Display is in percent.
The impulse length is thus proportional to the control deviation. If
the control deviation is beyond the slow step zone, the valves are
controlled using permanent contact.
This parameter can be set for special applications.
