11.12 T: Auto-Tuning922 YASKAWA ELECTRIC SIEP C710617 01B YASKAWA AC Drive GA700 Technical ManualIf the amount of PG (pulse generator, encoder) Z-pulse offset is unknown, or the encoder has been replaced,perform Z Pulse Offset Tuning and correct for the offset (Δθ) from the Z phase.◆ T3: ASR and Inertia Tuning■ T3-00: Control Loop Tuning SelectionNo.(Hex.) Name Description Default(Range)T3-00(1198)Control Loop TuningSelection Selects the Control Auto-Tuning method to be used.0(0 - 1)0 : Inertia Tuning1 : ASR Tuning■ T3-01: Test Signal FrequencyNo.(Hex.) Name Description Default Setting(Range)T3-01(0760)Test SignalFrequency Normally there is no need to change this setting. Sets the frequency of thetest signal applied to the motor during Inertia Tuning.3.0 Hz(0.1 - 20.0 Hz)Lower the setting value if the load inertia is too significant and a fault is detected after the Inertia Tuning.■ T3-02: Test Signal AmplitudeNo.(Hex.) Name Description Default Setting(Range)T3-02(0761)Test SignalAmplitude Sets the amplitude of the test signal applied to the motor during InertiaTuning. Normally there is no need to change this setting.0.5 rad(0.1 - 10.0 rad)Lower the setting value if the load inertia is too significant and a fault is detected after the Inertia Tuning. Adjustthis parameter if a fault occurs when T3-01 [Test Signal Frequency] is set to a low value.■ T3-03: Motor InertiaNo.(Hex.) Name Description Default Setting(Range)T3-03(0762)Motor InertiaSets the inertia of the motor. This value is used to determine the load inertiausing the test signal response.Determined by o2-04,C6-01, and E5-01(0.0001 - 6.0000kgm2)The default setting is for a Yaskawa standard motor as listed in the motor inertia table. Actual values varydepending on whether the motor used is an induction motor or a PM motor.Note:Capacities below 37 kW are set in units of 0.0001 kgm2. Capacities 37 kW and above are set in units of 0.001 kgm2 .■ T3-04: System Response FrequencyNo.(Hex.) Name Description Default Setting(Range)T3-04(0763)System ResponseFrequency C5-01 [ASR Proportional Gain 1] is automatically calculated and set usingthe load inertia value derived by the Inertia Tuning process.10.0 Hz(0.1 - 50.0 Hz)Oscillation may result if the value input here is too high.◆ T4: EZ TuningWith the T4 parameters, the data required for motor parameter auto-tuning is input when setting A1-02 = 8[Control Method Selection = EZ Open Loop Vector Control]. The following two modes are available.V/f CL-V/f OLV CLV AOLV OLV/PMOLV/PM AOLV/PM CLV/PM EZOLVV/f CL-V/f OLV CLV AOLV OLV/PMOLV/PM AOLV/PM CLV/PM EZOLVV/f CL-V/f OLV CLV AOLV OLV/PMOLV/PM AOLV/PM CLV/PM EZOLVV/f CL-V/f OLV CLV AOLV OLV/PMOLV/PM AOLV/PM CLV/PM EZOLVV/f CL-V/f OLV CLV AOLV OLV/PMOLV/PM AOLV/PM CLV/PM EZOLV
