12.6 E: Motor Parameters
834 YASKAWA SIEPC71061737D GA800 Drive Technical Reference
Note:
The display units are different for different models:
• 0.01 A: models 2004 - 2042, 4002 - 4023
• 0.1 A: models 2056 - 2415, 4031 - 4720, T103 - T720
The drive automatically sets E5-03 to the value input for “PM Motor Rated Current” after you do these types of Auto-
Tuning:
• Manual Entry w/ Motor Data Sheet
• PM Stationary Auto-Tuning
• Stationary (R Only)
• Rotational (Ld, Lq, R, back-EMF)
■ E5-04: PM Motor Pole Count
No.
(Hex.)
Name Description
Default
(Range)
E5-04
(032C)
PM Motor Pole Count
Sets the number of PM motor poles.
4
(2 - 120)
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 a PM motor. 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.
