Code Description (continuation of Table 43)
4011 INTERNAL SETPNT
Sets a constant value used for the process reference .
• Units and scale are defined by parameters 4006 and 4007.
4012 SETPOINT MIN
Sets the minimum value for the reference signal source . See parameter 4010 .
4013 SETPOINT MAX
Sets the maximum value for the reference signal source . See parameter 4010 .
4014 FBK SEL
Defines the PID controller feedback (actual signal).
• You can define a combination of two actual values (ACT1 and ACT2) as the feedback signal.
• Use parameter 4016 to define the source for actual value 1 (ACT1).
• Use parameter 4017 to define the source for actual value 2 (ACT2).
1 = ACT1 – Actual value 1 (ACT1) provides the feedback signal .
2 = ACT1-ACT2 – ACT1 minus ACT2 provides the feedback signal .
3 = ACT1+ACT2 – ACT1 plus ACT2 provides the feedback signal .
4 = ACT1*ACT2 – ACT1 times ACT2 provides the feedback signal .
5 = ACT1/ACT2 – ACT1 divided by ACT2 provides the feedback signal .
6 = MIN (A1, A2) – The smaller of ACT1 or ACT2 provides the feedback signal .
7 = MAX (A1, A2) – The greater of ACT1 or ACT2 provides the feedback signal .
8 = SQRT (A1-A2) – Square root of the value for ACT1 minus ACT2 provides the feedback signal .
9 = SQA1 + SQA2 – Square root of ACT1 plus the square root of ACT2 provides the feedback signal .
10 = SQRT (ACT1) – Square root of ACT1 provides the feedback signal .
11 = COMM FBK 1 – Signal 0158 PID COMM VALUE 1 provides the feedback signal .
12 = COMM FBK 2 – Signal 0159 PID COMM VALUE 2 provides the feedback signal .
13 = AVE(ACT1,2) – The average of ACT1 and ACT2 provides the feedback signal .
4015 FBK MULTIPLIER
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 SELECTED .
-32.768...32.767 = Multiplier applied to the signal defined by parameter 4014 FBK SEL.
Example: FBK = Multiplier ×√A1 – A2
4016 ACT1 INPUT
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 .
4017 ACT2 INPUT
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 .
