Figure4-67 Maximum permissible vibration velocity including vibration amplitude and vibration
acceleration for SH 180 to 280
To measure the vibration velocity, the measuring equipment must fulll the requirements of
ISO2954. The vibration acceleration must be measured as a peak value in the time range in a
frequency band of 10 to 2000 Hz.
If appreciable vibration excitation in excess of 2000 Hz (e.g. gear teeth meshing frequencies)
can be expected, the measurement range must be adapted accordingly. This does not alter
the maximum permissible values.
Note
Avoiding continuous operation at natural frequencies
Uninterrupted duty in the natural frequencies of the installed/mounted system should be
avoided, as this generally leads to the permissible vibration values being exceeded and the
system being damaged. To reduce vibration, anged-mounted motors can be supported at the
NDE.
Note
Measuring vibration values according to the standard
Vibration must be analyzed and measured (measuring points, etc.) according to standard
ISO10816-3.
Note
Increased resistance to vibration
1PH8 motors with shaft heights 180 and 225 and with the option L03 can be used in compliance
with certain operating conditions for applications with increased resistance to vibration (see
Chapter "Increased resistance to vibration (Page 178)"). Possible applications are, for example,
applications such as servo presses.
