12.12 T: Auto-Tuning750 YASKAWA SIEPC71061753A GA500 Technical Manual12.12 T: Auto-TuningNumbers identifying the T parameters are displayed when an LED keypad is used. The names of the parametersare displayed on the LCD screen of the LCD keypad. Set the following.• Induction Motor Auto-Tuning• PM Motor Auto-Tuning• ASR and Inertia Tuning◆ T0: Tuning Mode Selection■ T0-00: Tuning Mode SelectionWhen your control method supports Control Tuning, set T0-00 first. Then, set T1-00 [Motor 1/Motor 2 Selection]to select the motor you will tune. Then, set the tuning mode in T2-01 [PM Auto-Tuning Selection] or T3-00[Control Loop Tuning Selection].No.(Hex.) Name Description Default(Range)T0-00(1197)Tuning Mode SelectionSets the type of Auto-Tuning.0(0, 1)0 : Motor Parameter Tuning1 : Control TuningNote:The available tuning modes are different for different control methods.◆ T1: Induction Motor Auto-TuningT1 parameters set the Auto-Tuning input data for induction motor tuning.Note:• The base frequency of drive dedicated motors and special motors for use with vector control may be lower than the base frequency ofgeneral-purpose motors, which is 50 Hz or 60 Hz. In such cases, this lower frequency is used as the value for E1-06 [Base Frequency]and E1-04 [Maximum Output Frequency] after Auto-Tuning completes. If the maximum output frequency is too low and causesproblems, change the setting of E1-04 after Auto-Tuning completes.• The following induction motor parameters are set automatically.–E1-xx [V/f Pattern for Motor 1]–E2-xx [Motor Parameters]–E3-xx [V/f Pattern for Motor 2]–E4-xx [Motor 2 Parameters]■ T1-00: Motor 1/Motor 2 SelectionNo.(Hex.)

When H1-xx ≠ 16 the keypad will not show this parameter.1 : Motor 1Auto-Tuning automatically sets parameters E1-xx and E2-xx for motor 1.2 : Motor 2Auto-Tuning automatically sets parameters E3-xx and E4-xx for motor 2. Make sure that you connect motor 2 tothe drive for Auto-Tuning.■ T1-01: Auto-Tuning Mode SelectionNo.(Hex.)
