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. 10 Hz to 500 Hz @ 2 oct/min 1.0 Gs (0 to pk). Maximum displacement may apply below 10 Hz. 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 Gs RMS. The drive will operate without a hard error while being subjected to the following vibration levels. Table 4: Operating random vibration profile Frequency (Hz) G2/Hz 17 1.1 x E-03 45 1.1 x E-03 48 8.0 x E-03 62 8.0 x E-03 65 1.0 x E-03 150 1.0 x E-03 200 5.0 x E-04 500 5.0 x E-04 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. 10 Hz to 500 Hz @ 0.5 oct/min 5 Hz to 10 Hz 5.0 Gs (0 to pk). Maximum displacement may apply below 22 Hz. 25.4 mm peak to peak displacement. ST1.3 Series Product Manual, Rev. D 13
