118 YASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual
■ T2-08: Number of PM Motor Poles
Enter the number of motor poles.
■
T2-09: PM Motor Base Speed
Enter the motor rated speed in r/min.
Note: T2-09 will be displayed when in AOLV/PM and CLV/PM.
■ T2-10: PM Motor Stator Resistance
Enter the motor stator resistance per motor phase.
■
T2-11: PM Motor d-Axis Inductance
Enter the d axis inductance per motor phase.
■
T2-12: PM Motor q-Axis Inductance
Enter the q axis inductance per motor phase.
■
T2-13: Induced Voltage Constant Unit Selection
Selects the units used for setting the induced voltage coefficient.
0: mV (r/min)
1: mV (rad/sec)
Note: If T2-13 is set to 0, then the drive will use E5-24 (Motor Induction Voltage Constant 2), and will automatically set E5-09 (Motor
Induction Voltage Constant 1) to 0.0. If T2-13 is set to 1, then the drive will use E5-09 and will automatically set E5-25 to 0.0.
■ T2-14: PM Motor Induced Voltage Constant (Ke)
Enter the motor induced voltage constant (Ke).
■
T2-15: Pull-In Current Level for PM Motor Tuning
Sets the amount of pull-in current used to tune the d-axis and q-axis inductance. Set as a percentage of the motor rated
current.
