Description
Motor values supplied by the user that are used in the motor
model.
These parameters are useful for non-standard motors, or to
just get more accurate motor control of the motor on site. A
better motor model always improves the shaft performance.
Activates the motor model parameters 98.02...98.12.
Notes:
• Parameter value is automatically set to zero when ID run is
selected by parameter
of parameters 98.02...98.12
the motor characteristics identified during the ID run.
• Measurements made directly from the motor terminals
during the ID run are likely to produce slightly different
values than those on a data sheet from a motor
manufacturer.
• This parameter cannot be changed while the drive is
running.
Parameters 98.02...98.12
The values of parameters 98.02...
motor model.
Defines the stator resistance R
With a star-connected motor, R
winding. With a delta-connected motor, R
resistance of one winding.
Stator resistance in per unit.
Defines the rotor resistance R
Rotor resistance in per unit.
Defines the main inductance L
Main inductance in per unit.
Defines the leakage inductance
Leakage inductance in per unit.
Defines the direct axis (synchronous) inductance.
Note: This parameter is valid only for permanent magnet
motors.
Direct axis inductance in per unit.
Defines the quadrature axis (synchronous) inductance.
Note: This parameter is valid only for permanent magnet
motors.
Quadrature axis inductance in per unit.
Defines the permanent magnet flux.
Note: This parameter is valid only for permanent magnet
motors.
Permanent magnet flux in per unit.
