3 Factory 
setting 
The MICROMASTER 440 frequency inverter is set in the factory so that it can be 
operated without any additional parameterization. To do this, the motor parameters 
set in the factory (P0304, P0305, P0307, P0310), that correspond to a 4-pole 1LA7 
Siemens motor, must match the rated data of the connected motor (refer to the 
rating plate).

50/60 Hz DIP switch 
The default motor base frequency 
of the MICROMASTER inverter is 
50 Hz. For motors, which are 
designed for a base frequency of 
60 Hz, the inverters can be set to 
this frequency using the DIP50/60 
switch. 
¾
  OFF position:  
European defaults (Rated 
motor frequency = 50 Hz, 
Power in kW etc.) 
¾
 ON position:  
North American defaults  
(Rated motor frequency = 60 Hz, Power in hp etc.)
