7.4 Trial run
Commission the machine after assembly or inspection as follows:
● Start up the machine without a load. To do this, close the circuit breaker and do not, if at
● Switching the machine off again while it is starting up and still running at slow speed should
● Check the machine for noises or vibrations on the bearings or bearing shields as it runs.
● If the machine is not running smoothly or is emitting abnormal noises, de-energize it, and
● Continue to observe the motor for a while in no-load operation.
● If it runs perfectly, connect a load. Check whether it is running smoothly. Read off the values
● Monitor and log the temperatures of the bearings, windings, etc., until the system reaches

be kept to a bare minimum, for example for checking the direction of rotation or for checking
the required dimensions. Allow the machine to run down before switching it on again.
determine the cause of the fault as the motor runs down.
– If the mechanical operation improves immediately after the machine is switched off, then
the cause is magnetic or electrical.
– If the mechanical operation is not improved after switching off, then the cause is
mechanical. This can be an imbalance in the electrical machines or in the driven
machine, poor alignment of the machine unit, operation of the machine with the system

values for the working machine.
CAUTION
Keep within the vibration values
The vibration values encountered during operation must be satisfied in accordance with
DIN ISO 10816-3, as otherwise the motor could be damaged or destroyed.
