Monitoring drive components via vibration signals
Bearing
"Condition-monitoring-ready" option
With the option "condition-monitoring-ready", you can monitor the drive components at any
time via vibration signals to avoid unexpected plant downtimes. A change in the vibration
response is an early indication of imminent damage.
Condition-monitoring-ready motors are equipped with boreholes for inserting vibration
sensors. This allows you to position vibration sensors optimally and install condition
monitoring systems.

Motors with option G50
On motors with option G50, you can, for example, monitor the vibration severity at the ball
bearing using sensors. You can find out how to mount the sensors in chapter "Mounting
vibration sensors (Z-option G50) (Page 147)".
The ball pass frequencies of the ball bearings are stated on the bearing data labeling plate.
You will find the bearing data labeling plate near the rating plate. You can read out the
bearing natural frequencies from the QR code on the bearing data labeling plate.
Depending on the evaluation unit you use, you will be able to detect the specific frequencies
listed below.
The abbreviations have the following meaning:
BPFO: Ball Pass Frequency of Outer ring
BPFI: Ball Pass Frequency of Inner ring
BSF: Ball Spin Frequency
FTF: Fundamental Train Frequency
