Performing the calculation of motor and control data via OP
Parameter Description (Parameter name and factory setting (if not variable) in bold) Setting
P0340 = 1 Calculation of motor parameters
This parameter is required during commissioning in order to optimize the operating behavior of
the inverter. For the complete parameterization (P0340 = 1), in addition to the motor/control
parameters, parameters are pre-assigned which refer to the rated motor data (e.g. torque limits
and reference quantities for interface signals). A list of the parameters, which are calculated,
depending on the setting of P0340, are included in the parameter list.
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
If additional catalog data is known enter the data in P0341, P0342 and P0344.
P0341 = ? Motor inertia [kg*m
2
]
P0342 = ? Total/motor inertia ratio
P0344 = ? Motor weight (entered in kg)
If the ECD data is known, enter the data in P0350, P0354, P0356, P0358, P0360.
If the ECD data is not known, then: Set P0340 = 4. To calculate the controller settings and skip to END.
P0350 = ? Stator resistance (line) (entered in Ω)
Stator resistance in Ω of the motor which is connected (line). This parameter value doesn't
include the cable resistance.
P0354 = ? Rotor resistance (entered in Ω)
Defines the rotor resistance of the motor equivalent diagram (phase value).
P0356 = ? Stator leakage inductance (entered in mH)
Defines the stator leakage inductance of the motor equivalent diagram (phase value).
P0358 = ? Rotor leakage inductance (entered in mH)
Defines the rotor leakage inductance of the motor equivalent diagram (phase value).
P0360 = ? Main inductance (entered in mH)
Defines the main (magnetizing) inductance of the motor equivalent diagram (phase value).
P0340 = 3 Calculation of motor parameters
3: Calculation of V/f and Vector control
All of the parameters, dependent on the ECD data are calculated and, in addition, the controller
settings (P0340 = 4).
END The motor parameters have been calculated and it is now possible to return to the additional
parameterization in the Section "Adaptation to the application".
