Allowed storage conditions
Before re-storage, empty the liquid coolant from the liquid-cooled
motors to avoid frost damage.
Storage times motors
Irrespective of the storage duration - which can exceed the warranty period of
our products - the function is retained provided additional measures are taken
into account and carried out during commissioning. However, this does not
entail any additional warranty claims.
Storage time Measures for commissioning
< 1 year
Resurface the holding brake
1 ... 5 years
1.
Check the electric contacts to verify that they are free from
corrosion
2.
Let the motor run in without load for one hour at 800 ...
1000 rpm.
3.
Resurface the holding brake
> 5 years
1.
Replace bearings
2.
Replace encoders

If the cable or the cable jacket has porous parts, replace it; other‐
wise check the electric contacts to verify that they are free from
corrosion.
