Disassembly and exchange
2. Open the main switch
3. Make sure the main switch cannot be switched back on
4. Disconnection plug connections
When exchanging the motor, close open plug sides of power connec-
tions with protection caps if moistening with coolant/lubricant or
soiling must be expected (allowed soiling degree according to EN
50178: 2).
5. Replace the motor
Observe the machine manufacturer's instructions when exchanging
the motor mechanically.
6. Re-establish the plug connections
7. Re-establish the dimensional reference
WARNING
If servo axes are provided with an indirect position measuring system via
the motor encoder, the dimensional reference is lost after motor replace-
ment!
For this reason, the reference to the machine coordinate system must be
re-established.

9.3 Preparing storage

Before motors are stored, the protection covers on device connector, shaft and
input openings for cooling water in case of liquid-cooled motors which were at-
tached on delivery must be re-attached.
When motors are liquid-cooled, completely discharge the coolant from the cool-
ing tubes (e.g., via purging the coolant holes with pressure air). This will prevent
frost damage at storage temperatures lower than 0 °C.
