Parameters 347
98.13
Ld user SI
Defines the direct axis (synchronous) inductance.
Note:
This parameter is valid only for permanent magnet
motors.
0.00 mH
0.00 …100000.00 mH
Direct axis inductance.
1 = 10000
mH
98.14
Lq user SI
Defines the quadrature axis (synchronous) inductance.
Note:
This parameter is valid only for permanent magnet
motors.
0.00 mH
0.00 …100000.00 mH
Quadrature axis inductance.
1 = 10000
mH
98.15
Position offset user
Defines an angle offset between the zero position of the
synchronous motor and the zero position of the position
sensor.
Notes:
• The value is in electrical degrees. The electrical angle
equals the mechanical angle multiplied by the number
of motor pole pairs.
• This parameter is valid only for permanent magnet
motors.
0.0 deg
0.0...360.0 deg
Angle offset.
1 = 1 deg
99
99 Motor data
Motor configuration settings.
99.03
Motor type
Selects the motor type.
Note:
This parameter cannot be changed while the drive
is running.
Asynchro-
nous motor
Asynchronous motor
Standard squirrel cage AC induction motor (asynchronous
induction motor).
0
Permanent magnet
motor
Permanent magnet motor. Three-phase AC synchronous
motor with permanent magnet rotor and sinusoidal
BackEMF voltage.
Note:
With permanent magnet motors special attention
must be paid on setting the motor nominal values correctly
in this parameter group (
99 Motor data
). You must use
vector control. If the nominal BackEMF voltage of the
motor is not available, a full ID run should be performed
for improving performance.
1
SynRM motor
Synchronous reluctance motor. Three-phase AC
synchronous motor with salient pole rotor without
permanent magnets.
99.04
Motor control mode
Selects the motor control mode.
Scalar
Vector
Vector control. Vector control has better accuracy than
scalar control but cannot be used in all situations (see
selection Scalar below).
Requires motor identification run (ID run). See parameter
99.13 ID run requested
.
Note:
In vector control the drive performs a standstill ID
run at the first start if ID run has not been previously
performed. A new start command is required after
standstill ID run.
Note:
To achieve a better motor control performance, you
can perform a normal ID run without load.
