Test overview

■ Purpose

To conduct a seismic test of the control panel and confirm that there is no abnormality in operation

■ EUT

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

■ Implementation

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.
