Collect noise during fitting with a high-speed analog input module and perform FFT analysis with a PLC to eliminate quality inconsistencies caused by connector fitting operations that rely on the personnel's sense.
Obtain analog input signals without high-frequency noise components by using a primary delay filter.
Detect incomplete fitting by judging whether the input waveform is within the range of the reference waveform.
Key Points
- An interface module that captures analog signals from external devices to a PLC (Up to 4 channels in 5 μs.)
- FFT converts time-domain waveforms into frequency-domain waveform.
