2.8.6.1
Operating sweep sine vibration
The following lists the maximum operating sweep sine vibration levels that the drive may experience while
meeting the performance standards specified. It will consist of a forward and backward sweep from 10 Hz to
500 Hz to 10 Hz. The drive will operate without a hard error while being subjected to the following vibration
levels.
meeting the performance standards specified. It will consist of a forward and backward sweep from 10 Hz to
500 Hz to 10 Hz. The drive will operate without a hard error while being subjected to the following vibration
levels.
2.8.6.2
Operating random vibration
The test consists of 30 minutes of random vibration using the power spectral density (PSD) levels specified in
the table below. The vibration test level is 0.67
the table below. The vibration test level is 0.67
Gs RMS. The drive will operate without a hard error while being
subjected to the following vibration levels.
2.8.6.3
Nonoperating sweep sine vibration
The following table lists the maximum nonoperating sweep sine vibration levels that the drive may experience
while meeting the performance standards specified. It will consist of a forward and backward sweep from 5 Hz
to 500 Hz to 5 Hz. The drive will not incur any physical damage when subsequently put into operation.
