Judgment for Y-axis(force)Real time waveform!

Judgment for X-axis(displacement)‫ ڦ‬Waveform comparison judgement
Always compare preset waveform and measured waveform.
If even one point exceeds the preset waveform,
it will be judged as NOK.
Preset waveform

ٔ56.10Waveforms are always drawn when the power is turned on.
Able to detect abnormality immediately.

Measuring waveform!

Within range, OK

Exceeded, NOK

Utilization of waveform comparison
Judgment will output atthe moment the preset
waveform is touched,so it can be used forbranching the sequence
operation.

Forget to set workpiece.

Waveform that used for various judgements.
Waveform data can be also saved into SD card.

A variety of hold judgment

OK/NOK judgment can be done in one
single process. (Max. 5 points)
Choose from a variety of hold functions*.
Peak holdPeak hold

Bottom holdWorkpiece isout of place.

Trend analysis

With trend analysis, abnormality can be detected earlier toprevent unwanted failures.

Monitor the deviation of zero pointand changes of hold points!

Setting is completed just by entering setting values
such as position and load.
The set sequenceis registered in
the control recipe.

Values can be entered
not only withthe keypad, but alsowith the current value.

Various commands

Sequence can be branched out

Complex sequences such as load limits during position
control and linkage between control and measurement
can be easily set.

Sequence can be branched out based on the condition ofcurrent load, current displacement, I/O, timer, counter, etc.
