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)

¾Motor cooling P0335 = 0

¾Motor current limit P0640 = 150 %

¾Min. frequency

P1080 = 0 Hz

Analog output

¾Max. frequency P1082 = 50 Hz

¾Ramp-up time P1120 = 10 s

¾Ramp-down time P1121 = 10 s

¾Control mode P1300 = 0

3.150/60 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.

¾OFF position:

European defaults (Rated motor frequency = 50 Hz, Power in kW etc.)

Remove I/O board

DIP50/60

¾ON position:

North American defaults

(Rated motor frequency = 60 Hz, Power in hp etc.)
