05.24 : Transient inductance / Ld
Adjustment range : 0.000 to 9000.000 mH
Factory setting : 0.000 mH
Format: 32 bits
- Asynchronous motor: Value of the overall leakage inductance
applied to the typical machine stator. The value of 05.24 is
stored automatically during an autotune when running in flux
vector mode ( 05.12 = Rotating (2)).
- Synchronous motor: Value of the typical machine cyclical
stator inductance. The value of 05.24 is used in permanent
magnet motor sensorless control mode ( 03.38 = Software
encoder n°1 to Software encoder n° 4). Its value should be
entered from the nameplate data by setting a value
corresponding to 80% of the Ld value on the nameplate, or else
using the autotune procedure (see 05.12 ).
05.25 : Stator inductance (LS)
Adjustment range : 0.000 to 9000.000 mH
Factory setting : 0.000 mH
Format: 32 bits
- Asynchronous motor: Sum of the magnetising inductance
and the leakage inductance at the motor rated flux.
The value of 05.25 is stored automatically during an autotune
when running ( 05.12 = Running (2)).
- Synchronous motor: This parameter is not relevant with a
synchronous motor.
05.26
: Dynamic control enable
Reserved.
05.27 to 05.30 :Not used
05.31 : Defluxing loop gain
Adjustment range : 0 to 32000
Factory setting : 1000
Format: 16 bits
This parameter controls the gain of the drive output voltage
limiting loop. It only acts when the motor is operating above its
rated speed in the constant voltage zone (defluxing zone).
NB:
05.31
is only active for «Induction motor in vector control
mode» ( 11.31 =2), «PM motor (Servo) in vector control
mode» ( 11.31 =3), «Active rectifier for synchronous motor»
( 11.31 =5) modes.
05.32 : Motor torque per amp (Kt) ( )
Reserved.
05.33 : Motor volt per 1000 rpm (Ke) ( )
Adjustment range: 0 to 32000 V
Factory setting : 98 V
Format: 16 bits
Used to set the motor voltage per 1000 rpm.
The value of 05.33 is used in permanent magnet motor
sensorless control mode ( 03.38 = Software encoder n°1 to
Software encoder n°5). Its value should be entered from the
nameplate data (Ld value on the nameplate) or else using the
autotune procedure.
05.34
to
05.35
: Not used
05.36 : Low speed sensorless mode for PM motors
Adjustment range: Signal injection (0), Current vector (1),
None (2).
Factory setting: 1
Format: 8 bits
CAUTION:
05.36 is only active if 03.38 = «Software 3 /adaptive model»,
«Software 4 /flux oriented» or «Software 5»
Signal injection (0): At low speed, a current signal with high
frequency and low amplitude is injected into the motor stator.
The information collected is used to detect the rotor flux axis up
to the speed 0. This method can only be used on machines with
high cogging [Lq > 120% of Ld].
Current vector (1): On the run command, the motor is
«parked» in a known position. The «parking» current and time
are set by parameters 05.52 and 05.53 respectively. After the
«parking» phase, the drive applies a current rotating vector in
which the the acceleration ramp depends on parameter 02.11 .
When the machine speed reaches the value set in
05.64
,
control switches to the mode defined by 03.38 .
