Optimization Of Controller Data - Siemens SIPART PS2 Operating Instructions Manual

Operating
6.2 Operating modes
Diagnostics
Proceed as follows to call the "Diagnostics" mode from the "Automatic" or "Manual" modes:
Press the three buttons of the positioner at the same time for at least 2 seconds.
Current operating data can be called and displayed in this mode, e.g.:
● Number of total strokes
● Number of changes in direction
● Number of fault messages
Note
Setting the mode
The "Automatic" and "Manual" modes remain set when switching to the "Diagnostics"
mode. The positioner responds as per the configured mode:
• The predefined setpoint is used as the control variable in "Automatic" mode.
• The last reached position is retained in "Manual" mode.

Optimization of controller data

Note
Initializing
Initialize the positioner automatically before changing the parameter settings as per your
specific requirements.
The positioner determines the data for control quality automatically during the initialization
process.
The data determined is optimized for a short transient time in the case of minor overshoots.
The adjustment can be accelerated or the attenuation can be intensified by optimizing the
data.
The following special cases are suitable for targeted data optimization:
● Small actuators with travel times < 1 s.
● Operation with boosters, described in section "Operation with boosters (Page 273)"
