Tests on control panels
To conduct a seismic test of the control panel and confirm that there is no abnormality in operation
W600 × D450 × H1900 ㎜, 250 kg
■ Test conditions
Reference standard: JIS C 60068-3-3
- Vibration waveform: Sine beat wave
- Acceleration level: 6.0 m/s2
- Frequency: 5 Hz, 7.5 Hz, 11.3 Hz, 25.3 Hz, 35 Hz and resonance frequency
- Number of cycles: 5 times
- Wave number: 10 Cycle
- Pause time: 2 seconds
4 points on the bottom of the EUT were bolted.
A resonance exploration test was carried out before the seismic test, and the frequency with a response factor of 2 or more was adopted as the resonance frequency.
Operation was confirmed by energizing during sine beat wave excitation.
