0.1 ... 100.0
Use this sub-parameter to set the factor for formation of threshold
1.
Set the factor in a range from '0.1' to '100.0'. The threshold is the
product of the reference stroke time and 'AA.FACT1'. Determining
the reference stroke time is described under 'A9.PSTIN'.
The threshold 1 message is displayed when threshold 1 is excee‐
ded. The process to activate and display this message is described
in the 'XDIAG' parameter.
1.5
0.1 ... 100.0
Use this sub-parameter to set the factor for formation of threshold
2.
Set the factor in a range from '0.1' to '100.0'. The threshold is the
product of the reference stroke time and 'Ab.FACT2'. Determining
the reference stroke time is described under 'A9.PSTIN'.
The threshold 2 message is displayed when threshold 2 is excee‐
ded. The process to activate and display this message is described
in the 'XDIAG' parameter.
3.0
0.1 ... 100.0
Use this sub-parameter to set the factor for formation of threshold
3.
Set the factor in a range from '0.1' to '100.0'. The threshold is the
product of the reference stroke time and 'AC.FACT3'. The process
to determine the reference stroke time is described under
'A9.PSTIN'.
The threshold 3 message is displayed when threshold 3 is excee‐
ded. The process to activate and display this message is described
in the 'XDIAG' parameter.
The positioner responds in accordance with the option set in the sub-
parameter 'A7.FLBH - Behavior after failed PST'.
