PARAMETER DESCRIPTIONS VACON · 299
Use load drooping to get a dynamic speed drooping when the load changes. This parameter
gives the time during which the speed is restored 63% of the change.
657 CURRENT CONTROL TIME 6 (P2.6.23.18)
Use this parameter to adjust the integrator time constant of current controller. This value is
presented in seconds.
662 MEASURED VOLTAGE DROP 6 (2.6.25.16)
Use this parameter to set the measured voltage drop at stator resistance between two
phases with the nominal current of the motor.
The measured voltage drop at stator resistance between two phases with the nominal
current of the motor. This parameter is identified during the ID run. Set this value to gain the
optimum torque calculation for Open Loop low frequencies.
664 IR: ADD ZERO POINT VOLTAGE 6 (2.6.25.17)
Use this parameter to set the amount of voltage that is fed to the motor at zero speed when
the torque boost is used.
665 IR: ADD GENERATOR SCALE 6 (2.6.25.19)
Use this parameter to set the scaling factor for the generating side IR-compensation when
the torque boost is used.
667 IR: ADD MOTORING SCALE 6 (2.6.25.20)
Use this parameter to set the scaling factor for the motoring side IR-compensation when the
torque boost is used.
668 IU OFFSET 6 (2.6.25.21)
Use this parameter to set the offset value for the phase current measurement.
669 IV OFFSET 6 (2.6.25.22)
Use this parameter to set the offset value for the phase current measurement.
670 IW OFFSET 6 (2.6.25.23)
Use this parameter to set the offset value for the phase current measurement.
Identified during ID run.
673 LS VOLTAGE DROP 6 (P2.6.25.21)
Use this parameter to set the Ls voltage drop between two phases.
Leakage inductance voltage drop with nominal current and frequency of the motor. This
parameter defines the Ls voltage drop between two phases. Use identification run to
determine the optimum setting.
