■ T2-12 PMMot qAxis Inductance
No.
(Hex.)
Name Description
Default
(Range)
T2-12
(0736)
PMMot qAxis 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 KE Unit Selection
No.
(Hex.)
Name Description
Default
(Range)
T2-13
(0755)
KE Unit Selection
Sets the units that the drive uses to set the induced voltage constant.
1
(0, 1)
0 : mV/rpm
1 : mV/(rad/sec)
Note:
• When T2-13 = 0, the drive will use E5-24 [PM BackEMF L-L Vrms (mV/rpm)] and will automatically set E5-09 [PM BackEMF 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 PMMot KE Voltage Constant
No.
(Hex.)
Name Description
Default
(Range)
T2-14
(0737)
PMMot KE Voltage
Constant
Sets the motor induced voltage constant (Ke).
Determined by T2-13
(0.0 - 2000.0)
■ T2-15 PullInCurrLv@PM Motor Tuning
No.
(Hex.)
Name Description
Default
(Range)
T2-15
(0756)
PullInCurrLv@PM Motor
Tuning
Sets the level of the pull-in current as a percentage, where 100% = motor rated current. Usually it
is not necessary to change this setting.
30%
(0 - 120%)
If the load inertia is high, increase the setting value.
■ T2-16 PMMot PG PulsePerRevolution
No.
(Hex.)
Name Description
Default
(Range)
T2-16
(0738)
PMMot PG
PulsePerRevolution
Sets the number of PG (pulse generator, encoder) pulses.
1024 ppr
(1 - 15000 ppr)
Set the actual number of pulses for one full motor rotation.
■ T2-17 Enc Z-Pulse Offset
No.
(Hex.)
Name Description
Default
(Range)
T2-17
(0757)
Enc Z-Pulse Offset
Sets the encoder Z-pulse offset (Δθ) (pulse generator, encoder) that is listed on the motor
nameplate.
0.0°
(-180.0 - +180.0°)
If you do not know the quantity of encoder (pulse generator, encoder) Z-pulse offset, or if you replaced the
encoder, do Z Pulse Offset Tuning and correct for the offset (Δθ) from the Z phase.
◆ T3: ASR
■ T3-00 Control Loop Tune Selection
No.
(Hex.)
Name Description
Default
(Range)
T3-00
(1198)
Control Loop Tune
Selection
Sets the type of Control Auto-Tuning.
