2.6 E: Motor Parameters
312 YASKAWA TOEPYAIGA8002B GA800 Drive Programming
Note:
• When A1-02 = 7 [Control Method Selection = CLV/PM], the maximum value is 120.
• When A1-02 = 5, 6 or 8 [OLV/PM, AOLV/PM or EZOLV], the maximum value is 48.
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 Motor Resistance (ohms/phase)
No.
(Hex.)
Name Description
Default
(Range)
E5-05
(032D)
PM Motor Resistance (ohms/
phase)
Sets the resistance per phase of the PM motors. Set 50% of the line-to-line resistance.
0.100 Ω
(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.
1.00 mH
(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.
1.00 mH
(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 Back-EMF Vpeak (mV/(rad/s))
No.
(Hex.)
Name Description
Default
(Range)
E5-09
(0331)
PM Back-EMF Vpeak (mV/
(rad/s))
Sets the peak value of PM motor induced voltage.
0.0 mV/(rad/s)
(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 Back-EMF 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
