FBK MULTIPLIER
-32.768…32.767 0.001 0
Defines an extra multiplier for the PID FBK value defined by parameter 4014 FBK SEL.
• Used mainly in applications where the flow is calculated from the pressure
difference.
0 = NOT SELECTED.
-32.768…32.767 = Multiplier applied to the signal defined by parameter 4014 FBK
SEL.
Example:
4016
ACT1 INPUT
1…8 1 2

Defines the source for actual value 1 (ACT1).
1 = AI 1 – Uses analog input 1 for ACT1.
2 = AI 2 – Uses analog input 2 for ACT1.
3 = CURRENT – Uses current for ACT1, scaled so:
•Min ACT1 = 0 current
• Max ACT1 = 2 x nominal current
4 = TORQUE – Uses torque for ACT1, scaled so:
• Min ACT1= -2 x nominal torque
• Max ACT1 = 2 x nominal torque
5 = POWER – Uses power for ACT1, scaled so:
• Min ACT1 = -2 x nominal power
• Max ACT1 = 2 x nominal power
6 = COMM ACT 1 – Uses value of signal 0158 PID COMM VALUE 1 for ACT1.
7 = COMM ACT 2 – Uses value of signal 0159 PID COMM VALUE 2 for ACT1.
8 = FREQ INPUT
4017
ACT2 INPUT
1…8 1 2

Defines the source for actual value 2 (ACT2).
1 = AI 1 – Uses analog input 1 for ACT2.
2 = AI 2 – Uses analog input 2 for ACT2.
3 = CURRENT – Uses current for ACT2, scaled so:
•Min ACT2 = 0 current
• Max ACT2 = 2 x nominal current
4 = TORQUE – Uses torque for ACT2, scaled so:
• Min ACT2 = -2 x nominal torque
• Max ACT2 = 2 x nominal torque
5 = POWER – Uses power for ACT2, scaled so:
• Min ACT2 = -2 x nominal power
• Max ACT2 = 2 x nominal power
6 = COMM ACT 1 – Uses value of signal 0158 PID COMM VALUE 1 for ACT2.
7 = COMM ACT 2 – Uses value of signal 0159 PID COMM VALUE 2 for ACT2.
8 = FREQ INPUT – Frequency input.
