7.2  Switching on 
Before you switch on the motor, ensure that the parameters of the frequency converter have 
been assigned correctly. 
Use appropriate commissioning tools (e.g. "Drive ES" or "STARTER"). 
 
CAUTION 
 
Uneven running or abnormal noise 
The motor can be damaged by improper handling during transport, storage, or assembly. If 
a damaged motor is operated, this can damage the windings or bearings and could even 
completely destroy the motor. 
If the motor is not running smoothly or is making abnormal noises, switch it off and 
determine the cause of the fault as the motor coasts down. 
 
CAUTION 
 
Pay attention to the maximum speed 
The maximum speed n
max
 is the highest permissible operating speed. The maximum speed 
is specified on the rating plate. 
Exceeding speed n
max
 can result in material damage or could even completely destroy the 
motor. An appropriately configured control or an active speed monitoring function in the 
drive should be used to ensure that the motor cannot exceed the permissible speeds.
