Factory setting
Calculation of motor parameters
This parameter is required during commissioning in order to optimize the
operating behavior of the drive 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.

Calculation of motor parameters
4 Calculates the controller setting (refer to parameter P0340)
Stator resistance (line-to-line) (entered in Ω)
Stator resistance in Ω of the motor which is connected (from line-to-line). This
parameter value also includes the cable resistance.
Rotor resistance (entered in Ω)
Defines the rotor resistance of the motor equivalent diagram (phase value).
Stator leakage inductance (entered in mH)
Defines the stator leakage inductance of the motor equivalent diagram
(phase value).
Rotor leakage inductance (entered in mH)
Defines the rotor leakage inductance of the motor equivalent diagram
(phase value).
Main inductance (entered in mH)
Defines the main (magnetizing) inductance of the motor equivalent diagram
(phase value).
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).
The motor parameters have been calculated and it is now possible to return to
the additional parameterization in the Section 3.5.7 "Commissioning the
application".
