YASKAWA SIEPC71061737D GA800 Drive Technical Reference 1063
■ T2-15: Pull-In Current Level
No.
(Hex.)
Name Description
Default
(Range)
T2-15
(0756)
Pull-In Current Level
Sets the level of the pull-in current as a percentage of E5-03 [PM Motor Rated Current (FLA)].
Usually it is not necessary to change this setting.
30%
(0 - 120%)
If the load inertia is high, increase the setting value.
■ T2-16: Encoder Pulse Count (PPR)
No.
(Hex.)
Name Description
Default
(Range)
T2-16
(0738)
Encoder Pulse Count (PPR)
Sets the number of PG (pulse generator, encoder) pulses.
1024 ppr
(1 - 15000 ppr)
Set the actual number of pulses for one full motor rotation.
■ T2-17: Encoder Z-Pulse Offset
No.
(Hex.)
Name Description
Default
(Range)
T2-17
(0757)
Encoder Z-Pulse Offset
Sets the encoder Z-pulse offset (Δθ) (pulse generator, encoder) that is listed on the motor nameplate.
0.0 °
(-180.0 - +180.0°)
If you do not know the quantity of encoder (pulse generator, encoder) Z-pulse offset, or if you replaced the encoder,
do Z Pulse Offset Tuning and correct for the offset (Δθ) from the Z phase.
◆ T3: ASR and Inertia Tuning
■ T3-00: Control Loop Tuning Selection
No.
(Hex.)
Name Description
Default
(Range)
T3-00
(1198)
Control Loop Tuning
Selection
Sets the type of Control Auto-Tuning.
0
(0 - 3)
0 : Inertia Tuning
1 : ASR (Speed Regulator)
2 : Deceleration Rate Tuning
3 : KEB Tuning
Note:
Settings 0 and 1 are available only when A1-02 = 3, 7 [Control Method Selection = CLV, CLV/PM].
■ T3-01: Test Signal Frequency
No.
(Hex.)
Name Description
Default
(Range)
T3-01
(0760)
Test Signal Frequency
Sets the frequency of the test signal applied to the motor during Inertia Tuning. Usually it is not
necessary to change this setting.
3.0 Hz
(0.1 - 20.0 Hz)
If the load inertia is too large and the drive detects a fault after Inertia Tuning, decrease the setting.
■ T3-02: Test Signal Amplitude
No.
(Hex.)
Name Description
Default
(Range)
T3-02
(0761)
Test Signal Amplitude
Sets the amplitude of the test signal applied to the motor during Inertia Tuning. Usually it is not
necessary to change this setting.
0.5 rad
(0.1 - 10.0 rad)
