Gain V

The gain V

can be set in different ways. By using byPCharacteristic you can select the function you

require.

With nActVp you can display the actual value of the gain V

byPCharacteristic = 0:

 The gain V

is provided by nVp.

byPCharacteristic = 1:

Fig. 2−76 The gain V

is provided by nAdapt_a

 The gain V

is provided by nAdapt_a. The input value is led via a linear characteristic. The

slope of the characteristic is fixed by nVp(upper limit) and nVp2Adapt (lower limit). The value in

nVp is valid if the input value = +100 % or −100 % (100 % = 16384). The value in nVp2Adapt is

valid if the input value = 0.

Fig. 2−77 The gain V

derived from the process setpoint nSet_a

 The gain V

is derived from the process setpoint nSet_a. The setpoint is acquired after the

ramp generator, and calculated from a characteristic with 3 interpolation points.

byPCharacteristic = 3:

 The gain V

is derived from the control difference, and led by the same characteristic

generation as for byPCharacteristic = 2.
