7.139 (ID 662) Stator Resistance Voltage Drop
Location in the menu:
•
INU application: P3.1.2.7.2
Use this parameter to set the measured voltage drop at stator resistance between two phases with the nominal current of the mo-
tor (in star-connection equivalent circuit). The resistance is essential for an accurate motor control. Set this value to gain the opti-
mum torque calculation for Open Loop low frequencies.
The value is given as a percentage of voltage drop at nominal current.
The identification run sets a value for this parameter automatically. If possible, make the identification run. You can make the
identification run with the parameter ID 631.
7.140 (ID 665) Torque Boost Generator Gain
Location in the menu:
•
INU application: P3.1.4.11
Use this parameter to set the scaling factor for the generating side IR-compensation when the torque boost is used.
7.141 (ID 667) Torque Boost Motor Gain
Location in the menu:
•
INU application: P3.1.4.10
Use this parameter to set the scaling factor for the motoring side IR-compensation when the torque boost is used.
7.142 (ID 672) Short Restart Delay
Location in the menu:
•
INU application: P3.2.12
Use this parameter to set the time delay during which the drive cannot be restarted if flying start is used.
