Figure 5-35 Max. permissible vibration velocity, taking into account the vibration displacement and
vibration acceleration
To evaluate the vibration velocity, the measuring equipment must meet the requirements of
ISO 2954. Evaluate the vibration acceleration as a peak value in the time domain in a
frequency band extending from 10 up to 2000 Hz.
Appropriately adapt the measuring range if it is expected that noticeable vibration levels are
excited above 2000 Hz (e.g. as a result of gear tooth meshing frequencies). This does not
alter the maximum permissible values.
5.4.10 Mounting vibration sensors (Z-option G50)
The end shield and the adapters of the motors are equipped with M8 sensor boreholes for
screwing in vibration sensors.
Depending on the motor type, adapters are supplied for the M8 sensor connection. For this
and further information, see the following figure "Position and dimensions of the sensor
boreholes for the vibration sensors".
The adapters are fastened in pairs on the lifting eye. Where applicable, mount the adapter
on the motor.
Remove the screw plugs before mounting the adapters.
You do not always need both adapters. Dispose of unnecessary adapters and screws in the
proper manner.
Observe a maximum permissible tightening torque of 3 Nm when screwing the vibration
sensors into the adapter.
The adapters protrude beyond the mounting flange of the motor and produce geometric
interference. If geometric interference occurs, remove the adapters and use the M6 sensor
holes.
