Analog Comparator - IDEC FL1E-H12RCA User Manual

4.4.18 Analog comparator

Short description
The output is set and reset depending on the difference Ax -
Ay and on two configurable thresholds.
Symbol in IDEC
* AI1...AI8: 0...10 V corresponds with 0...1000 (internal value).
Gain and offset parameters
For more information on the gain and offset parameters,
refer to Chapter 4.3.6.
Parameters On and Off
The on threshold On and the off threshold Off can be
provided by the actual value of another already-programmed
function. You can use the actual values of the following
functions:
• Analog comparator (actual value Ax - Ay, see Chapter
4.4.18)
• Analog trigger (actual value Ax, see Chapter 4.4.16)
• Analog amplifier (actual value Ax, see Chapter 4.4.20)
• Analog multiplexer (actual value AQ, see Chapter 4.4.26)
• Analog ramp control (actual value AQ, see Chapter
4.4.27)
• Analog math (actual value AQ, see Chapter 4.4.30)
• PI controller (actual value AQ, see Chapter 4.4.28)
• Up/down counter (actual value Cnt, see Chapter 4.4.13)
Select the required function by the block number.

Description
You apply the analog signals the
difference of which you want to
analyze at the inputs Ax and Ay.
Use the analog inputs AI1...AI8
analog memory markers AM1...AM6,
the block number of a function with
analog output, or the analog outputs
AQ1 and AQ2.
Range of values: 10.00
B: Zero offset Range of values:
10,000
On: On threshold
Range of values: 20,000
Off: Off threshold
Range of values: 20,000
p: Number of decimals
Range of values: 0, 1, 2, 3
Q is set or reset, depending on the
difference Ax - Ay and the set
thresholds.
