Disassembly and Exchange
12.1
Changing the Motor
Lethal electric shock by live parts with more
than 50 V!
WARNING
The supply unit may only be replaced by qualified personnel which have
been trained to perform the work on or with electrical devices.
The motor should be replaced by a motor of identical type. This is
the only way to ensure that all parameterizations can remain un‐
changed. Moreover, repeated acceptance within the scope of the
"Integrated switching technology" function is not required.
1. If necessary, note down the previous absolute value
2. Open the main switch
3. Ensure that the main switch cannot be accidentally switched on again
4. Disconnection plug connections
When exchanging the motor, close open plug sides of power con‐
nections with protection caps if moistening with coolant/lubricant
or soiling must be expected (allowed soiling degree according to
EN 50178: 2).
5. Exchange the motor
Observe the machine manufacturer's instructions when exchang‐
ing the motor mechanically.
6. Re-establish the plug connections
7. Re-establish the dimensional reference
Risk of accidents due to unintentional
axis movements!
WARNING
If servo axes are provided with an indirect position measuring system
via the motor encoder, the dimensional reference is lost after motor re‐
placement!
For this reason, the reference to the machine coordinate system must
be re-established.
