Page 8: Factory Setting
Issue 04/04 Factory setting The MICROMASTER 420 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). -

The frequency inverter is adapted to the motor using the quick commissioning function and important technological parameters are set. The quick commissioning shouldn't be carried-out if the rated motor data saved in the frequency inverter (4-pole 1LA Siemens motor, star circuit configuration frequency inverter (FU)- specific) match the rating plate data. - Page 14 Time taken for motor to decelerate from maximum motor frequency (P1082) down to standstill when no rounding is used 5.00 s OFF3 ramp-down time P1135 =...
