Variable Selector 1 Source 1/2; Variable Selector 1 Mode; Variable Selector 1 Destination; Variable Selector 1 Output - Emerson 2202 Advanced User's Manual

Parameter Parameter
Introduction
x.00 description format
12.08 Variable selector 1 source 1
12.09 Variable selector 1 source 2
Bit SP
Coding
Range Pr 0.00 to Pr 21.51
Default Pr 0.00
Update rate Read on drive reset
These parameters and Pr 12.28 and Pr 12.29 define the parameters which are to be switched by the variable selector block. These can be bit
variables or non bit variables. If programming a reference to a variable source select, if the reference is a whole number, then the variable source
treats the whole number as a percentage, e.g. 5.0Hz = 10% of reference.
12.10

Variable selector 1 mode

Bit SP
Coding
Range 0 to 9
Default 0
Update rate 21 ms
The output of the variable select can be changed by the mode as in the following table:
Mode value
Action
(Pr 12.10)
0 Select input 1
1 Select input 2
2 Add
3 Subtract
4 Multiply
5 Divide
6 Time constant
7 Linear ramp
8 Modulus
9 Raise to power
12.11

Variable selector 1 destination

Bit SP
Coding
Range Pr 0.00 to Pr 21.51
Default Pr 0.00
Update rate Read on drive reset
Defines the destination parameter for the variable selector 1 output. Only non-protected parameters can be programmed as a destination. If a non-
valid parameter is programmed, the output is not routed anywhere.
12.12

Variable selector 1 output

Bit SP
Coding
Range ±100.0%

output = (input1 x input2) / 100.0
output = (input1 x 100.0) / input2
output = input1 / ((control param)s + 1)
output = input1 via a ramp with a ramp time of (control param)

output = input1
control = 0.02: output = input1
control = 0.03: output = input1
control has any other value: output = input 1
