P3.1.2.15 STATOR RESISTANCE VOLTAGE DROP (ID 662)
Use this parameter to set the motor stator phase-resistance value (in star-connection
equivalent circuit). The resistance is essential for an accurate motor control.
The value is given as a percentage of voltage drop at nominal current.
NOTE!
The identification run sets a value for this parameter automatically. We
recommend that you make the identification run, if it is possible. You can make the
identification run with the parameter P3.1.2.4.
P3.1.2.16 STATOR INDUCTANCE VOLTAGE DROP (ID 673)
Use this parameter to set the motor stator phase-inductance value (in star-connection
equivalent circuit). The value is the transient inductance (for induction motors) or the line-to-
neutral inductance (for permanent magnet and reluctance motors).
The value is given as a percentage of voltage drop at nominal current and nominal frequency.
NOTE!
The identification run sets a value for this parameter automatically. We
recommend that you make the identification run, if it is possible. You can make the
identification run with the parameter P3.1.2.4.
