67Motor Leakage InductanceThis information is not used for induction motors and therefore theparameter is not visible in induction motor mode.This is the total phase to phase reflected leakage inductance of themotor winding. The inductance listed on the manufacturer’s datasheet will most likely be for one phase. So it will be necessary tomultiply the value by two and then enter it into the drive. Incorrectsettings of this parameter could lead to oscillation in the currentcontrol since the regulator values for the current control are calculatedfrom this value.Unit: mHValue range: 0.01...500.00Factory setting: 1.00Adjustment value: enter the value from the manufacturer’s datasheet.This parameter not required for closed loop induction motor opera-tion and will not be visible in these modes. In open loop control thisis the phase to phase motor stator resistance or twice the perwinding value. The value can be measured by the drive automati-cally, see section 5.5.3. Otherwise the data can be entered from themanufacturer’s data sheet or measured manually with a DVM. Ifmeasuring manually measure all three phase to phase combina-tions and take the average value. Note: if you scroll up passed Auto,the number will loop back to 0.001 and vise versa.Unit: ohmsValue range: 0.000...49.999, AutoFactory setting: 49.999Adjustment value: enter the motor resistance valueFor PM motors it is not possible to automatically measure theresistance value, there for it must be measured manually with a DVMor entered from the manufacturer’s data sheet. The resistance listedon the manufacturer’s data sheet will most likely be for one phase.So it will be necessary to multiply the value by two and then enter itinto the drive. Incorrect settings of this parameter could lead tooscillation in the current control since the regulator values for thecurrent control are calculated from this value.Unit: ohmsValue range: 0.000...49.999Factory setting: 49.999Adjustment value: enter the motor resistance valueMotor Stator ResistanceParameter Description - Motor DataIMPMIMPM
