is derived from the process setpoint PCTRL1−SET. The setpoint is
obtained after the ramp generator and calculated via the characteristic with three
co−ordinates.

l C0329 = 3
– The input of gain V
p
is derived from the control difference and led via the characteristic
generation as C0329 = 2.

is entered under C1332.
2.4.50.2 Ramp generator
The setpoint PCTRLx−SET is led by a ramp generator with linear characteristic. Thus, setpoint
step−changes at the input can be transformed into a ramp.
