6.6 Vibration and shock

All vibration and shock measurements in this section are for drives without mounting attachments for sys-
tems. The input level shall be applied to the normal drive mounting points.
Vibration tests and shock tests are to be conducted by mounting the drive to a table using the bottom four
mounting holes.

6.6.1 Operating vibration

The drive will operate without a hard error while being subjected to the following vibration levels.
6.6.1.1 Random vibration
The test consists of 30 minutes of random vibration using the power spectral density (PSD) levels speci-
fied in C-S 1-9711-002 (1990-03) as V5L. The vibration test level for V5L is 0.67 G RMS (Root Mean
Square).
