The following description is for variable selector 1, but variable selector 2 operates in the same way. The source parameters selected with
Variable Selector 1 Source 1
(12.008) and
Variable Selector 1 Source 2
(12.009) are converted to a percentage value, scaled with
Variable Selector 1 Source 1 Scaling
(12.013) and
Variable Selector 1 Source 2 Scaling
(12.014) respectively and then combined with a function defined
by
Variable Selector 1 Mode
(12.010) to give
Variable Selector 1 Output
(12.012) as a percentage value. If
Variable Selector 1 Enable
(12.016) = 1 then
the function operates normally. If
Variable Selector 1 Enable
(12.016) = 0 then
Variable Selector 1 Output
(12.012) = 0.00% and any states within the
function are reset (i.e. the time constant function accumulator is held at zero). If the value of
Variable Selector 1 Mode
(12.010) is changed then all
internal function state are also reset.
The table below shows the functions that can be selected with
Variable Selector 1 Mode
(12.010).
Variable Selector 1 Mode
(12.010)
Variable Selector 1 Output
(12.012)
0: Input 1
Input 1
1: Input 2
Input 2
2: Add
Input 1 + Input 2
3: Subtract
Input 1 - Input 2
4: Multiply
(Input 1 x Input 2) / 100.00%
5: Divide
(Input 1 x 100.00%) / Input 2
6: Time Const
Input 1 / (1 + τs) where τ =
Variable Selector 1 Control
(12.015) seconds
7: Ramp
Input 1 as an input to a linear ramp function where the time to ramp from 0.00% to 100.00% is defined by
Variable Selector 1 Control
(12.015) seconds
8: Modulus
|Input1|
9: Powers
If
Variable Selector 1 Control
(12.015) = 0.02 then Input
2
/ 100.00%
Else if
Variable Selector 1 Control
(12.015) = 0.03 then Input
3
/ 100.00%
Else Input 1
10: Sectional
See description below
Sectional Controller
If
Variable Selector 1 Mode
(12.010) = 10 then the variable selector can be used to provide a sectional control function. (Variable selector 2 operates in
the same way.) The sectional control function is intended to apply scaling and a speed offset to a 16 bit position value to generate a new 16 bit position
value. The output can be used as an input to the Standard motion controller (Menu 13) and to generate an encoder simulation output (Menu 3).
