0.1 ... 100.0
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". The actuator moves during the partial stroke test from the
start position to the target position. The target position is deter-
mined from the interaction between start position (A1.STPOS),
stroke height (A3.STRKH) and stroke direction (A4.STRKD).

Use this sub-parameter to set the stroke direction of the partial
stroke test. The following parameter values are available:
• uP: Actuator moves upward
• do: Actuator moves downward
• uP do: Actuator moves up and down
uP (only upward):
• The actuator moves from its start position to the target position.
• After reaching the target position, the actuator moves back to
the start position.
The target position is determined from the start position
(A1.STPOS) plus the stroke height (A3.STRKH).
do (only downward): The same procedure is applicable in the re-
verse order.
uP do (upward and downward):
• The actuator first moves from its start position to the high target
position.
• It then moves from the high target position to the low target
position.
• After reaching the low target position, the actuator moves back
to the start position.
The high target position is determined from the start position
(A1.STPOS) plus the stroke height (A3.STRKH). The low target
position is determined from the start position (A1.STPOS) minus
the stroke height (A3.STRKH).
