P6.21 T2 Analog Input 1 Minimum Input
Range: 0.00 to 100.00 % Default: 0.00 %
P6.22 T2 Analog Input 1 Percentage at Minimum Input
Range: -100.00 to 100.00 % Default: 0.00 %
P6.23 T2 Analog Input 1 Maximum Input
Range: 0.00 to 100.00 % Default: 100.00 %
P6.24 T2 Analog Input 1 Percentage at Maximum Input
Range: -100.00 to 100.00 % Default: 100.00 %
These parameters define the scaling of analog input 1 and can be used to limit the range, offset, invert and scale the input value.
The parameters define two points to scale how the drive interprets the measured input as below.
Figure 7-18 Scaling
Limiting the input range
Set P6.21 and P6.23 to the required range. If the input level is at or below the level set in P6.21, the value of T2 Analog Input 1 Percentage (P1.15)
is equal to P6.22. If the level is at or above P6.23, the value of P1.15 is equal to P6.24.
Offset
Use P6.22 to offset the value of analog input 1 Percent.
Inverting the input
To invert the input so that the value of P1.15 decreases as the input on T2 increases, Set P6.22 to 100.00 % and P6.24 to 0.00 %.
Example:
If 5 V on the input should equal 0 % of T2 Analog Input 1 Percentage (P1.15), P6.21 should be set to 50 %. If the analog input is selected as a
reference, 0 V to 5 V would equal a reference of 0 Hz, 6 V would equal a reference of 10 Hz, and 10 V = 50 Hz.
If T2 Analog Input 1 Minimum Input (P6.21) ≥ T2 Analog Input 1 Maximum Input (P6.23) then T2 Analog Input 1 Percentage (P1.15) = 0.00 %
whatever the input level.
P6.25 T4 Analog Input 2 Minimum Input
Range: 0.00 to 100.00 % Default: 0.00 %
P6.26 T4 Analog Input 2 Percentage at Minimum Input
Range: -100.00 to 100.00 % Default: 0.00 %
P6.27 T4 Analog Input 2 Maximum Input
Range: 0.00 to 100.00 % Default: 100.00 %
P6.28 T4 Analog Input 2 Percentage at Maximum Input
Range: -100.00 to 100.00 % Default: 100.00 %
These scaling parameters apply to T4 analog input 2. See the description below T2 Analog Input 1 Minimum Input (P6.21).
