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).
Further factory setting:
¾ Command sources P0700 = 2 (Digital input, see Fig. 3-1)
¾ Setpoint source P1000 = 2 (Analog input, see Fig. 3-1)
Analog output
¾ Motor cooling
P0335 = 0
¾ Motor current limit
P0640 = 150 %
¾ Min. frequency
P1080 = 0 Hz
¾ Max. frequency
P1082 = 50 Hz
¾ Ramp-up time
P1120 = 10 s
¾ Ramp-down time
P1121 = 10 s
¾ Control mode
P1300 = 0

3.1 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.

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.)
