Table 3-9 Parameter For Motor/Control Data; Calculating The Motor / Control Data - Siemens MICROMASTER 420 Operating Instructions Manual

3.5.3

Calculating the motor / control data

Internal motor / control data is calculated using parameter P0340 or, indirectly
using parameter P3900 (refer to Section 3.5.2) or P1910 (refer to Section 3.5.4).
The functionality of parameter P0340 can, for example, if the motor weight or the
stator resistance is known. The following settings are possible for P0340:
0 No calculation
1 Complete parameterization
For the complete parameterization (P0340 = 1), in addition to the motor / control
parameters, parameters are also pre-assigned which refer to the motor rated data
(e.g. torque limits and reference quantities for interface signals).

P0344 Motor weight
P0346 Magnetization time
P0347 Demagnetization time
P0350 Stator resistance (line-to-line)
P0611 Motor I2t time constant
P1253 Vdc-controller output limitation
P1316 Boost end frequency
P2000 Reference frequency
P2002 Reference current
NOTE
When exiting the quick commissioning with P3900 > 0 (refer to Section 3.5.2),
internally P0340 is set to 1 (complete parameterization).
For the motor data identification (refer to Section 3.5.4), after the measurement
has been completed, internally P0340 is set to 3.
