High Vibration

Too much vibration can cause erroneous feedback and damage positioner. The SIPART
PS2 vibration specifications are:
● Harmonic oscillations (sine-wave) according to EN 60068-2-6/10.2008
– 3.5 mm (0.14"), 2 ... 27 Hz, 3 cycles/axis, 98.1 m/s² (321.84 ft/s²), 27 ... 300 Hz, 3
● Bumping (half-sine) according to EN 60068-2-27/02.2010
– 150 m/s² (492 ft/s²), 6 ms, 1000 shocks/axis
● Noise (digitally controlled) according to EN 60068-2-64/04.2009
– 10 ... 200 Hz; 1 (m/s²)²/Hz (3.28 (ft/s²)²/Hz)
– 200 ... 500 Hz; 0.3 (m/s²)²/Hz (0.98 (ft/s²)²/Hz)4 hours/axis
● Recommended continuous duty range of the complete fitting
– <= 30 m/s² (98.4 ft/s²) without resonance sharpness
● If excessive vibration cannot be avoided, consider Non-Contacting technology. Contact
Siemens technical support for assistance: 1-800-333-7421.
