The valve moves to the valve position Step start (Code 49 - d2)
and Step end (Code 49 - d3) with certain control pulses. The dif-
ference between these control pulses creates the delta y value
[1/s].
The y-monitoring reference value applies to the adjusted step
values (Code 49 - d2 and Code 49 - d3) and for the selected
ramp times (Code 49 - d5 and Code 49 - d6). The y-monitoring
reference value must be determined again if any of the above
mentioned values change.
Activates/deactivates delta y-monitoring
The percentage [%] of the entire range of the control pulse be-
tween 1 and 10000 1/s (Example: 10 % = 10000 1/s)
The partial stroke test is canceled if the change in control signal
(delta y) varies from the y-monitoring reference value by this
amount.

Ramp time for 0 to 100 % travel (rising) of the ramp function.
Do not enter a ramp time which is lower than the value automati-
cally given during initialization.
