KSM: Storage times
Additional measures must be taken on commissioning to preserve proper
functioning – irrespective of the storage time which may be longer than the
warranty period of our products. However, this does not involve any
additional warranty claims.

Measures for commissioning
> 1 > 12 > 60
■ ■ ■ Visual inspection of all parts to be damage-free
■ ■ ■ Resurface the holding brake
■ ■
Check the electric contacts to verify that they are free from
corrosion
■ ■ Let the motor run in without load for one hour at 800 ... 1000 rpm
■ ■
Measure insulation resistance. Dry the winding at a value of <
1kohm per volt rated voltage.
■ Replace bearing
■ Replace encoder
