4.5. Evaluation of the Real Cutting Length: F07.062 = 4
This mode uses encoder 1 as a length counter and encoder 2 is not active. All counting occurs
in the background and is not visible in the display. The counter gets started and stopped by
remote control signals, and the final counting result appears in the display (frozen) whilst the
counter already executes the next cycle in the background.
For remote start and stop signals the inputs Cont.1 and Cont.2 must be used, therefore these
inputs are no more available for other purpose. All assignments of the signals and the active
edges (rising or falling) can individually be set to match with the actual measuring situation.
Examples:
-
use the rising edge of the Cont1 input to latch and reset, This will display your cutting
length as shown in the picture below.
-
Use Cont1 to start the measuring cycle and Cont2 to stop and latch. This will display the
differential length between the two remote signals
-
Use the same signal in parallel to Cont1 and Cont2. This e.g. allows to measure a gap or
distance between two products, while the remote signal is high (or low)
This mode is useful to get information about the actual cutting length with applications like
Rotary Cutters, Flying Shears and similar procedures. The automatic reset function is
automatically on in order to ensure that the next measuring cycle will restart at zero.
Besides the actual cutting length the unit also records the extreme length values (minimum and
maximum) of all cuts.
Presets K1 and K2 are related to the actual counter value of encoder 1 (live background
counter). Presets K3 and K4 are related to the real cutting lengths shown in the frozen display.
Therefore K3 and K4 can be used for quality sorting purpose (e.g. too short – good – too long)
