LG-9200 and TM-3130 are in use. 25 small cut reflective marks are affixed to φ 60 rotating body to measure. Analog output (0 to 10 V) waveform from TM is monitored with memory high coder.
Regarding the pulse count, the waveform is output at regular intervals, but the entire analog output waveform fluctuates.
(There are large and small (strong and weak) fluctuations (in up and down directions)). Please tell me the estimated reason and solution for the case.
Estimated reason: the reflective marks are not affixed at regular intervals.
(There is a possibility that the whole analog output waveform fluctuates
because the cycles are not constant.)
Solution: Please affix the reflective marks exactly at equal intervals.
