Display Offset Function
Normally the count value returns to “0” after resetting, but with this
function, the initial value can be set to any desired value.
Hold Function
When “hold” is input, the counter holds the current count value in
memory. Next, when the count value is read into a PLC which
uses serial or BCD output, etc., the count value that was held can
be read in, even if there is a time lag.
Setting the Tolerances of Preset Values
Count Value Protection
In the current model CEU1, the preset value tolerances could only
be set as ±, but now it has become possible to set an upper and
lower limit of + 앪 mm and – 쑶 mm.
By including preset tolerance setting, superior performance is
exhibited in parts inspections, etc. In a workpiece to be measured,
there are tolerances which assure a good product. For example, in
the case of 10 , the CEU5 allows these tolerances to be input
as they stand. If the workpiece is within tolerances the OK signal is
sent.
On the other hand, in ordinary counters, no. 1 is set to 9.98 and
no. 2 is set to 10.06, and if no. 1 is ON and no. 2 is OFF, an
acceptance decision is made. 2 points of output are used in order
to check whether or not the product is within dimension tolerances.
In this example, one preset of the CEU5 performs the same
function as two presets of an ordinary counter.
In the past, the count value returned to “0” when the power supply
was cut off, but this function holds the previous value even after a
power failure. This function can be switched between active and
inactive settings.
Cylinder Stop Output
When workpiece discrimination is performed using a preset
counter, it has been common to estimate the amount of time from
the cylinder's start of operation until it touches the workpiece and
stops, using a timer to read the output after a fixed amount of time.
Since cylinder stop output is now output when there is no cylinder
movement for a fixed amount of time, timing of preset output and
external output, etc. is simplified.

Tolerances can be set with the preset value.
OK/NG signal is output by the counter.
Labor savings can be realized in parts
inspections.
