■ T2-08: Number of PM Motor Poles
No.
(Hex.)
Name Description
Default
(Range)
T2-08
(0734)
Number of PM Motor Poles
Sets the number of motor poles.
4
(2 - 120)
■ T2-09: PM Motor Base Speed
No.
(Hex.)
Name Description
Default
(Range)
T2-09
(0731)
PM Motor Base Speed
Sets the motor base speed (min
-1
(r/min)).
1750 min
-1
(r/min)
(0 - 34500 min
-1
(r/min))
■ T2-10: PM Motor Stator Resistance
No.
(Hex.)
Name Description
Default
(Range)
T2-10
(0754)
PM Motor Stator Resistance
Sets the stator resistance for each motor phase.
Determined by T2-02
(0.000 - 65.000 Ω)
Note:
This parameter does not set line-to-line resistance.
■ T2-11: PM Motor d-Axis Inductance
No.
(Hex.)
Name Description
Default
(Range)
T2-11
(0735)
PM Motor d-Axis
Inductance
Sets the d-axis inductance of the motor on a per phase basis.
Determined by T2-02
(0.00 - 600.00 mH)
■ T2-12: PM Motor q-Axis Inductance
No.
(Hex.)
Name Description
Default
(Range)
T2-12
(0736)
PM Motor q-Axis
Inductance
Sets the q-Axis inductance of the motor on a per phase basis.
Determined by T2-02
(0.00 - 600.00 mH)
■ T2-13: Back-EMF Units Selection
No.
(Hex.)
Name Description
Default
(Range)
T2-13
(0755)
Back-EMF Units Selection
Sets the units that the drive uses to set the induced voltage constant.
0
(0, 1)
0 : mV/(rev/min)
1 : mV/(rad/s)
Note:
• When T2-13 = 0, the drive will use E5-24 [PM Back-EMF L-L Vrms (mV/rpm)] and will automatically set E5-09 [PM Back-EMF Vpeak
(mV/(rad/s))] = 0.0.
• When T2-13 = 1, the drive will use E5-09 and will automatically set E5-24 = 0.0.
■ T2-14: Back-EMF Voltage Constant (Ke)
No.
(Hex.)
Name Description
Default
(Range)
T2-14
(0737)
Back-EMF Voltage Constant
(Ke)
Sets the motor induced voltage constant (Ke).
Determined by T2-13
(0.0 - 2000.0)
