Use this sub-parameter to define the stroke height of the partial
stroke test in percent. Set the stroke height in a range from '0.1' to
'100.0'.

Use this sub-parameter to set the stroke direction of the partial
stroke test.
uP: Actuator only moves upward
● The actuator moves from its start position to the upper target
position.
● After reaching the upper target position, the actuator moves back
to the start position.
Upper target position = Start position (A1.STPOS) ± Start tolerance
(A2.STTOL) + Stroke height (A3.STRKH)
do: Actuator only moves downward
● The actuator moves from its start position to the lower target
position.
● After reaching the lower target position, the actuator moves back
to the start position.
Lower target position = Start position (A1.STPOS) ± Start tolerance
(A2.STTOL) + Stroke height (A3.STRKH)
uP do: Actuator moves up and down
● The actuator first moves from its start position to the upper target
position.
● It then moves from the upper target position to the lower target
position.
● After reaching the lower target position, the actuator moves back
to the start position.
Target position = Start position (A1.STPOS) ± Start tolerance
(A2.STTOL) + Stroke height (A3.STRKH)
