Code Description
4005 ERROR VALUE INV
Process error value inversion. Normally, a decrease in feedback signal causes
an increase in drive speed. If a decrease in feedback signal is desired to cause
a decrease in speed, set
0 =
NO
1 =
YES
4006 ACTUAL VAL SEL
PID controller feedback (actual) signal selection. Feedback signal can be a
combination of two actual values
selected by parameter 4007 and source for actual value 2 is selected by
parameter 4008.
1 = 1
ACT
Actual value 1 is used as the feedback signal.
2 = 1-
ACT ACT
Difference of actual values 1 and 2 is used as the feedback signal.
3 = 1+
ACT ACT
Sum of actual values 1 and 2.
4 = 1*
ACT ACT
Product of actual values 1 and 2.
5 = 1/
ACT ACT
Quotient of actual values 1 and 2.
6 = ( 1,
MIN A
Smaller of actual values 1 and 2.
7 = ( 1,
MAX A
Greater of actual values 1 and 2.
8 = sq (A1-A2)
Square root of difference of actual values 1 and 2.
9 = sqA1 + sqA2
Sum of square roots of actual values 1 and 2.
4007 ACT1 INPUT SEL
Source for actual value 1 (
1 = AI 1
Analogue input 1 is used as actual value 1.
2 = AI 2
Analogue input 2 is used as actual value 1.
4008 ACT2 INPUT SEL
Source for actual value 2 (
1 = AI 1
Analogue input 1 is used as actual value 2.
2 = AI 2
Analogue input 2 is used as actual value 2.
