E6581611F-866[Selection 2: Setting vector control and auto-tuning independently]Set vector control, automatic torque boost, energy saving and auto-tuning individually.After setting pt (V/F control mode selection), auto-tuning starts.Set the auto-tuning parameter f400 to 2 (Auto-tuning enabled)[Parameter setting]Title Function Adjustment range Default settingf400 Auto-tuning0: Auto-tuning disabled1: Initialization of f402 (after execution : 0)2: Auto-tuning executed(after execution: 0)3: -4: Motor constant auto calculation(after execution: 0)5: 4+2 (after execution: 0)0Set f400 to 2 before the start of operation. Auto-tuning is performed at the start of the motor and setf402, f412., Precautions on auto-tuning(1) Conduct auto-tuning after the motor has been connected properly and operation completelystopped.If auto-tuning is conducted immediately after operation stops, the presence of a residual voltagemay result in abnormal tuning.(2) Voltage is applied to the motor during tuning even though it barely rotates. During tuning,“” is displayed on the operation panel.(3) Tuning is performed when the motor starts for the first time after f400 is set to 2.Tuning is usually completed within three seconds. If it is aborted, the motor will trip with thedisplay of etn1 and no constants will be set for that motor.(4) High-speed motors, high-slip motors or other special motors cannot be auto-tuned. For thesemotors, perform manual tuning using Selection 3 described below.(5) Provide cranes and hoists with sufficient circuit protection such as mechanical braking. Insufficientmotor torque while tuning may cause machine stalling/falling.(6) If auto-tuning is impossible or an "etn1" auto-tuning error is displayed, perform manual tuningwith selection 4.[Selection 3: Setting vector control and motor constant automatically]After setting vl, vlv, f405, f415 and f417, motor constants calculated automatically.f402, f412 and f416 are set automatically.Set the motor constant parameter f400 to 4 (auto calculation)Set f400=5, when auto-tuning is executed after setting motor constants automatically.
