12.5 E: MOTOR
SIEPYEUOQ2A01G AC Drive Q2A Technical Manual 645
These types of Auto-Tuning will automatically set this parameter to the value of [Number of Motor Poles]:
• PM Motor Parameter Settings
• PM Stationary Auto-Tuning
• PM Rotational Auto-Tuning
■ E5-05 PM Mot Resistance (Ohms/Phase)
No.
(Hex.)
Name Description
Default
(Range)
E5-05
(032D)
PM Mot Resistance (Ohms/
Phase)
Sets the resistance per phase of the PM motors. Set 50% of the line-to-line resistance.
Determined by E5-01
(0.000 - 65.000 Ω)
PM motor Auto-Tuning automatically sets this parameter to the value of [PM Motor Stator Resistance].
Note:
Do not change the setting calculated by Auto-Tuning unless it is necessary.
■ E5-06 PM d-Axis Inductance (mH/Phase)
No.
(Hex.)
Name Description
Default
(Range)
E5-06
(032E)
PM d-Axis Inductance
(mH/Phase)
Sets the PM motor d-axis inductance.
Determined by E5-01
(0.00 - 300.00 mH)
PM motor Auto-Tuning automatically sets this parameter to the value of [PM Motor d-Axis Inductance].
Note:
Do not change the setting calculated by Auto-Tuning unless it is necessary.
■ E5-07 PM q-Axis Inductance (mH/Phase)
No.
(Hex.)
Name Description
Default
(Range)
E5-07
(032F)
PM q-Axis Inductance
(mH/Phase)
Sets the PM motor q-axis inductance.
Determined by E5-01
(0.00 - 600.00 mH)
PM motor Auto-Tuning automatically sets this parameter to the value of [PM Motor q-Axis Inductance].
Note:
Do not change the setting calculated by Auto-Tuning unless it is necessary.
■ E5-09 PM BackEMF Vpeak (mV/(rad/ s))
No.
(Hex.)
Name Description
Default
(Range)
E5-09
(0331)
PM BackEMF Vpeak (mV/
(rad/ s))
Sets the peak value of PM motor induced voltage.
Determined by E5-01
(0.0 - 2000.0 mV/(rad/s))
Set this parameter when you use an IPM motor with derated torque (SSR1-series) or an IPM motor with constant
torque (SST4-series).
PM motor Auto-Tuning automatically sets this parameter to the value of [Back-EMF Voltage Constant (Ke)].
When E5-01 = FFFF, only set E5-09 or E5-24 [PM BackEMF L-L Vrms (mV/rpm)] as the induced voltage
constant.
Note:
When you set this parameter, also set E5-24 = 0.0. The drive will detect oPE08 [Parameter Selection Error] in these conditions:
• E5-09 = 0.0 and E5-24 = 0.0
• E5-09 ≠ 0.0 and E5-24 ≠ 0.0
■ E5-11 Enc ZPulse Offset
No.
(Hex.)
Name Description
Default
(Range)
E5-11
(0333)
Enc ZPulse Offset
Sets the encoder Z-pulse offset.
0.0 degrees
(-180.0 - +180.0 degrees)
