_____________________________________________________________________________________
7.4.4.2
Vibration a.
Operating
The drive, as installed for normal operation, shall operate error free while subjected to continuous vibration not exceeding
5-22 Hz @ 0.040 inches (1.03 mm) displacement peak-to-peak
22-400 Hz @ 1.0 g
Vibration may be applied in the X, Y, or Z axis.
b.
Nonoperating
The limits of nonoperating vibration shall apply to all conditions of handling and transportation. This includes both isolated drives and integrated drives.
The drive shall not incur physical damage or degraded performance as a result of continuous vibration not exceeding
5-22 Hz @ 0.081 inches (2.05 mm) displacement peak-to-peak
22-400 Hz @ 2.00 g’s
Vibration may be applied in the X, Y, or Z axis.
7.4.5
Air cleanliness
The drive is designed to operate in a typical office environment with minimal environmental control.
7.5
7.5.1
Electromagnetic compatibility
Electromagnetic susceptibility
As a component assembly, the drive is not required to meet any susceptibility performance requirements. It is the responsibility of the system integrator to perform those tests required to ensure that equipment operating in the same system as the drive does not adversely affect the performance of the drive. See section 6.1.2, and see Table 7.2-1, DC Power Requirements.
