2.6 E: Motor Parameters
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.
Name
(Hex.)
E5-05 PM Motor Resistance (ohms/
phase)
(032D)
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.
Name
(Hex.)
E5-06 PM d-axis Inductance (mH/
phase)
(032E)
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.
Name
(Hex.)
E5-07 PM q-axis Inductance (mH/
phase)
(032F)
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.
Name
(Hex.)
E5-09 PM Back-EMF Vpeak (mV/
(rad/s))
(0331)
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
