n 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.
n T2-14: PM Motor Induced Voltage Constant (Ke)
Enter the motor induced voltage constant.
n
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.
n
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.
n
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.
