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.
P3.1.2.17 MOTOR BEM VOLTAGE (ID 674)
Use this parameter to set the back electromotive force (back-EMF) voltage of a permanent
magnet motor. The value of this parameter is the motor terminal voltage when the motor
current is zero.
The value is given as line-to-line RMS voltage at nominal operating frequency. Identification
at standstill uses this parameter to set U/f curve in open loop control mode. The back-EMF
value that is identified in Identification with rotation overwrites the existing parameter value.

MOTOR LIMITS
P3.1.3.1 MOTOR CURRENT LIMIT (ID 107)
Use this parameter to set the maximum motor current from the AC drive.
The range of values for the parameter is different for each enclosure size of the drive.
When the current limit is active, the drive output frequency decreases.
NOTE!
The Motor Current Limit is not an overcurrent trip limit.
P3.1.3.2 MOTOR TORQUE LIMIT (ID 1287)
Use this parameter to set the maximum torque limit of the motoring side.
The range of values for the parameter is different for each enclosure size of the drive.
P3.1.3.3 GENERATOR TORQUE LIMIT (ID 1288)
Use this parameter to set the maximum torque limit of the generating side.
The range of values for the parameter is different for each enclosure size of the drive.
P3.1.3.4 MOTOR POWER LIMIT (ID 1289)
Use this parameter to set the maximum power limit of the motoring side.
The range of values for the parameter is different for each enclosure size of the drive.
