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.
No. Name Setting Range Default
T2-15 Pull-In Current Level for PM Motor Tuning 0 to 120% 30%
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.
No. Name Setting Range Default
T2-16 PG Number of Pulses Per Revolution for PM Motor Tuning 1 to 15000 ppr 1024 ppr
n T2-17: Encoder Z Pulse Offset (ΔΘ)
Sets the amount of compensation or offset in 0.1 degree units to fine-tune the home position. Perform Z Pulse tuning when
the amount of offset needed for the Z Pulse is unknown or if the PG encoder is replaced.
No. Name Setting Range Default
T2-17 Encoder Z Pulse Offset (ΔΘ) -180.0 to 180.0 deg 0.0 deg

Parameter Settings during Inertia and Speed Control Loop Auto-Tuning: T3
These tuning methods apply a sine wave test signal to the system. The drive estimates the system inertia by the measuring the
response and automatically sets the parameters listed in Table 4.22 .

n T3-01: Inertia Tuning Frequency Reference
Sets the frequency of the test signal applied to the motor during Inertia Tuning. Although this setting rarely needs to be changed,
increasing the value may be beneficial when working with high inertia loads.
No. Name Setting Range Default
T3-01 Inertia Tuning Frequency Reference 0.1 to 20.0 Hz 3.0 Hz
n T3-02: Inertia Tuning Reference Amplitude
Enter the amplitude of the test signal applied to the motor during Inertia Tuning. Although this setting rarely needs to be
changed, decrease the setting if a large load inertia causes problems during Inertia Tuning. Adjust T3-02 if a fault occurs when
T3-01 is set to a low value.
No. Name Setting Range Default
T3-02 Inertia Tuning Reference Amplitude 0.1 to 10.0 rad 0.5 rad
n
T3-03: Motor Inertia
Enter the inertia of the motor. This value is used to determine the load inertia using the test signal response. The default setting
is for a Yaskawa standard motor as listed in the motor inertia table.
