The vibration magnitudes must not exceed the limits defined in DIN ISO 10816-3 as shown in
the table below. This will ensure flawless commutation, low brush wear, and long bearing life.

If higher levels of vibration than the above specified occur in operation, special measures must
be taken. For more information, please contact your local Siemens sales office.
8.2 Regreasing roller bearings
Refer to the regreasing instructions for the roller bearings on the lubricant plate.
8.3 Deactivating
● If not controlled automatically, switch on the anti-condensation heating if installed. This
prevents damage to the winding insulation.
● If not controlled automatically, switch any external fans and fans off.
8.4 Switching on again after an emergency switching-off
● Check the machine before recommissioning the driven machine after an Emergency Off.
● Eliminate all the causes that have led to the emergency off
8.5 Stoppages
The stoppage is a shutdown for a period of time, during which the machine is stopped but
remains at the location of use.
Under normal ambient conditions, e. g. the stopped machine is not exposed to any vibration,
no increased level of corrosion, etc. in general, the following measures are necessary during
stoppages.
