T2-12: PM Motor q-Axis Inductance
■
Enter the q axis inductance per motor phase.
No.
T2-12
■ T2-13: Induced Voltage Constant Unit Selection
Selects the units used for setting the induced voltage coefficient.
No.
T2-13
Setting 0: mV (min -1 )
Setting 1: mV (rad/s)
Note: If T2-13 is set to 0, then the drive will use E5-24 (Motor Induction Voltage Constant 2 (for PM Motors)), and will automatically
set E5-09 (Motor Induction Voltage Constant 1 (Ke) (for PM Motors)) 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).
No.
T2-14
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.
No.
T2-15
T2-16: PG Number of Pulses Per Revolution for PM Motor Tuning
■
Enter the number of pulses from the PG encoder per motor rotation. Set the actual number of pulses for one full motor
rotation.
No.
T2-16
T2-17: Encoder Z-Pulse Offset (Δθ)
■
Sets the amount of compensation or offset in 0.1 degree units in order to fine-tune the home position. If the amount of
offset needed for the Z pulse is unknown or if the PG encoder is replaced, perform Z pulse tuning.
No.
