MICROMASTER 420 Operating Instructions

3.4 Factory setting
The MICROMASTER drive unit is shipped from the
plant with a Status Display Panel (SDP, refer to Fig.
3-12). The SDP has two LEDs on the front panel
which display the operating state of the drive inverter
(refer to Section 4.1).
When MICROMASTER is shipped from the plant with
the SDP functioning, it can be operated without any
additional parameterization. In this case, the drive
inverter default settings (which depend on the drive
inverter type / size) match the following data of a 4-
pole motor:
 Rated motor power P0307
 Rated motor voltage P0304
 Rated motor current P0305
 Rated motor frequency P0310
(We recommend a Siemens standard motor.)
Further, the following conditions must be fulfilled:
 Control (ON/OFF command) via digital inputs (refer to Table 3-7)
 Setpoint input via analog input 1 P1000 = 2
 Induction motor P0300 = 1
 Self-cooled motor P0335 = 0
 Motor overload factor P0640 = 150 %
 Min. frequency P1080 = 0 Hz
 Max. frequency P1082 = 50 Hz
 Ramp-up time P1120 = 10 s
 Ramp-down time P1121 = 10 s
 Linear V/f characteristic P1300 = 0
