4015 FBK MULTIPLIER -32.768…32.767 0.001 0.000
Defines an extra multiplier for the PID FBK value defined by parameter 4014.
• Used mainly in applications where the flow is calculated from the pressure difference.
0 =
NOT USED.
-32.768…32.767 = Multiplier applied to the signal defined by parameter 4014
FBK SEL.
Example:
4016 ACT1 INPUT 1…5 1 2 9
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
4017 ACT2 INPUT 1…5 1 2 9
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
4018 ACT1 MINIMUM -1000…1000% 1% 0%
Sets the minimum value for
ACT1.
• Used with analog input min/max settings (e.g. 1301
MINIMUM AI1, 1302 MAXIMUM AI1).
• Scales analog inputs used as actual values.
• See figure: A= Normal; B = Inversion (
ACT1 MINIMUM > ACT1 MAXIMUM)
4019 ACT1 MAXIMUM -1000…1000% 1% 100%
Sets the maximum value for
ACT1.
• See 4018
ACT1 MINIMUM.
4020 ACT2 MINIMUM -1000…1000% 1% 0%
Sets the minimum value for
ACT2.
• See 4018
ACT1 MINIMUM.
