3.11.11 Ramp function
Restrictions which apply particularly to this function:
• There is no preselection to which of both, source mode and sink mode, the function is applied to; the settings
decide whether it’s “source mode only”, “sink mode only” or a mixture of both
• When applying the function to the voltage, the device can only switch to and work in sink mode if the external
voltageon theDCterminalishigherthan thehighestpoint(o󰀨set+amplitude)ofthewaveandthe current
setting “I Sink” isn’t 0
Thefollowingparameterscanbeconguredforarampfunction:
Value Range Description
Ustart / Uend 0...U
Nom
Start/end value in U mode
Istart / Iend -I
Nom
...+I
Nom
Start/end value in I mode
t1 0,1 ms...36000 s Time before ramp-up or ramp-down of the signal.
t2 0.1 ms...36000 s Ramp-up or ramp-down time
10 h after reaching the ramp end, the function will stop automatically (i.e. I = 0 A, in case the
ramp was assigned to the current), unless it has been stopped manually before.
