Parameter Descriptions
13-10 Comparator Operand
Option: Function:
NOTICE
[226] Touch on
Target
This option is available only with
software version 48.20 and newer.
Target position is reached in touch probe
position mode.
NOTICE
[227] Touch Activated
This option is available only with
software version 48.20 and newer.
Touch probe positioning active. The
frequency converter monitors the touch
probe sensor input.
[249] Therm. Sensor
Temp.
13-11 Comparator Operator
Option: Function:
Select the operator to be used in the
comparison. This is an array parameter containing
comparator operators 0–5.
[0] < The result of the evaluation is true when the
variable selected in parameter 13-10 Comparator
Operand is smaller than the fixed value in
parameter 13-12 Comparator Value. The result is
false if the variable selected in
parameter 13-10 Comparator Operand is greater
than the fixed value in
parameter 13-12 Comparator Value.
[1] ≈ (equal) The result of the evaluation is true when the
variable selected in parameter 13-10 Comparator
Operand is approximately equal to the fixed value
in parameter 13-12 Comparator Value.
[2] > Inverse logic of option [0] <.
[5] TRUE

3.13.3 RS Flip Flops

The reset/set flip flops hold the signal until set/reset.
Illustration 3.55 Reset/Set Flip Flops
2 parameters are used, and the output can be used in the
logic rules and as events.
Illustration 3.56 Flip Flop Outputs
The 2 operators can be selected from a long list. As a
special case, the same digital input can be used as both
set and reset, making it possible to use the same digital
input as start/stop. The following settings can be used to
set up the same digital input (for example, DI32) as start/
stop.
