Calculation Of Motor Parameters - Siemens MICROMASTER 440 Parameter Manual

Parameter Description
P0340[3]

Calculation of motor parameters

CStat: CT
P-Group: MOTOR
Calculates various motor parameters (see table below). This parameter is required during commissioning to
optimize inverter performance.
Possible Settings:
0 No calculation
1 Complete parameterization
2 Calculation of equivalent circuit data
3 Calculation of V/f and vector control data
4 Calculation of controller settings only

No calculation
P0340 = 1:
The motor weight/moment of inertia (P0344, P0341) are determined starting from the rating plate
parameters (P0300 - P0335), the motor equivalent circuit diagram parameters (ESB, P0350 - P0369). The
V/f control/vector control parameters and reference quantities are then pre-assigned (includes all of the
calculations from P0340 = 2,3,4).
P0340 = 2:
The motor equivalent circuit diagram parameters (ESB, P0350 - P0369) are calculated starting from the
rating plate parameters (without any other pre-assignments made).
P0340 = 3:
The V/f control/vector control parameters are determined (includes all calculations from P0340 = 4) starting
from the motor equivalent circuit diagram parameters (ESB, P0350 - P0369) and motor weight/moment of
inertia, moment of inertia ratio (P0344, P0341, P0342).
P0340 = 4:
The vector control parameters are pre-assigned starting from the motor equivalent circuit diagram
parameters (ESB, P0350 - P0369) and motor weight/moment of inertia, moment of inertia ratio (P0344,
P0341, P0342).
