7.1 Preparing for commissioning
Once the system has been correctly installed, you should check the following prior to
commissioning. It may be necessary to perform additional checks and tests in accordance with
the situation specific to the particular place of installation.
● The motor has been assembled and aligned properly.
● All mounting bolts, connecting elements and electrical connections are firmly tightened.
● The operating conditions correspond to the data specified on the rating plate.
● The bearings have been regreased as appropriate for the model.
● The machine is connected so that it rotates in the direction specified
● The cover sheets have been remounted correctly to ensure effective cooling of the motor.
● The rotor is fully able to turn and does not contact other parts at any point during rotation.
● All electrical and mechanical connections are secure. The function is assured.
● Any supplementary motor monitoring devices have been correctly connected.
● Appropriately configured control and speed monitoring functions ensure that the motor
cannot exceed the permissible speeds specified on the rating plate.
● If the motor is operated continuously under light-load conditions of I < 50 %, there is a risk
of high brush wear or problems with the commutator. Please consult the manufacturer if
this type of operation is intended.
The power output elements have the proper setting conditions according to type, for
example:
– Couplings are aligned and balanced.
– The belt tension is properly adjusted if there is a belt drive.
– Gear tooth flank play and gear tooth tip play, as well as radial play, are properly adjusted
if there is a gearwheel output.
● The minimum insulation resistance values are within tolerance.
