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.
