MIN(ACT1,2) Selects the smaller of ACT1 and ACT2 6
MAX(ACT1,2) Selects the higher of ACT1 and ACT2 7
sqrt(ACT1-2) Square root of the subtraction of ACT1 and ACT2 8
sqA1+sqA2 Addition of the square root of ACT1 and the square root of ACT2 9
sqrt(ACT1) Square root of ACT1. 10
4015 FBK MULTIPLIER Defines an extra multiplier for the value defined by parameter 4014 FBK SEL.
Parameter is used mainly in applications where feedback value is calculated
from an other variable (e.g. flow from pressure difference).
0.000
-32.768…32.767 Multiplier. If parameter value is set to zero, no multiplier is used.
4016 ACT1 INPUT Defines the source for actual value 1 (ACT1). See also parameter 4018
ACT1 MINIMUM.
1 = AI 1
AI1 Uses analog input 1 for ACT1 1
POT Uses potentiometer for ACT1 2
CURRENT Uses current for ACT1 3
TORQUE Uses torque for ACT1 4
POWER Uses power for ACT1 5
4017 ACT2 INPUT Defines the source for actual value 2 (ACT2). See also parameter 4020
ACT2 MINIMUM.
1 = AI 1
See parameter 4016 ACT1 INPUT.
4018 ACT1 MINIMUM Sets the minimum value for ACT1.
Scales the source signal used as the actual value ACT1 (defined by
parameter 4016 ACT1 INPUT).
A= Normal; B = Inversion (ACT1 minimum > ACT1 maximum)
0%
-1000…1000% Value in percent
4019 ACT1 MAXIMUM Defines the maximum value for the variable ACT1 if an analog input is
selected as a source for ACT1. See parameter 4016 ACT1 INPUT. The
minimum (4018 ACT1 MINIMUM) and maximum settings of ACT1 define how
the voltage/current signal received from the measuring device is converted to
a percentage value used by the process PID controller.
See parameter 4018 ACT1 MINIMUM.
