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
rotor angle offset parameter 98.15.
Notes:
• Parameter value is automatically set to zero when ID run is
selected by parameter
of parameters 98.02...98.15
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 datasheet from a motor
manufacturer.
• This parameter cannot be changed while the drive is
running.
Parameters 98.02...98.15
The values of parameters
motor model.
The value of parameter
offset. Parameters 98.02...98.14
The values of parameters
motor model, and the value of parameter
rotor angle offset.
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
Note: This parameter is valid only for asynchronous motors.
Rotor resistance in per unit.
Defines the main inductance L
Note: This parameter is valid only for asynchronous motors.
Main inductance in per unit.
Defines the leakage inductance
Note: This parameter is valid only for asynchronous motors.
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.
98.02...98.14
99.13 ID run requested. The values
are then updated according to
inactive.
98.02...98.14 are used as the
98.15 is used as the rotor angle
are inactive.
98.02...98.14 are used as the
98.15 is used as the
of the motor model.
