Cleaning

WARNING

Electric shock when cleaning due to failing to observe the protection class

When cleaning, especially with high-pressure cleaning equipment, water can enter

energized parts and cause an electric shock.
•

Clean the motor in a manner appropriate for its protection class.

•

Avoid pressurized water on connectors, terminal boxes, and other live parts.

Clean the motor of dust and dirt as required. In this way, you ensure adequate heat

dissipation.

9.2.3

Bearing replacement interval

The bearings are subject to wear and must be replaced after a defined number of operating

hours.
For average load levels, the bearings must be replaced after approx. 25,000 hours.

Note

When replacing the motor bearings, always replace the encoder as well. For more

information on encoder replacement, see Service manual replacing an encoder

(

https://support.industry.siemens.com/cs/document/99457853/encoder-replacement-in-1fk7-

g2-and-1ft7?dti=0&dl=en&pnid=13308&lc=de-WW

Bearing replacement intervals can be extended if the motor is operated under favorable

conditions, e.g. low average speeds, low radial forces (cantilever forces), vibration load.

Note
Harsh operating conditions

If the motor is subject to harsh operating conditions (e.g. continuous operation at n

max

, high

vibration/shock loads, frequent reversing duty etc.), the bearing replacement intervals t

can

decrease by up to 50%.
