keyboard LED display "t-01". Motor automatic stop while self adjustment is over.Inverter return to standby state.
2: Static self-tuning Before self adjustment, [F05.01-F05.06] of motor which is controlled must be set as right value.
While self adjustment, motor at static state, it automatic detects motor stator resistance, motor rotor resistance, motor
stator&rotor inductance. All results will be auto wrote in the corresponding code and renewed while adjustment is over.
After parameter setting, press FWD key to start self study, keyboard LED display "t-02".FWD indicator is off while self
adjustment is over.Inverter return to standby state.
Note: [F05.20] is automatic set as 0 after self adjustment.
Cautions:
Before setting [F05.20] to "1" for rotary self-tuning, the motor shaft should be removed from the load as
much as possible, and the motor should be prohibited from carrying a heavy load for self-tuning of the
rotation parameters. Otherwise, the inverter will report the learning failure. The lighter the learning load
is, the better the learning accuracy will be. The asynchronous motor load is recommended not to
exceed 30% of the rated load, and the synchronous motor is recommended not to exceed 20% of the
rated load.
In some occasions (such as when the motor cannot be disconnected from the load), it is not convenient
to perform self-tuning in rotation type. For asynchronous motors, static learning can be used to learn
the full parameters of the motor except the encoder parameters. If you run the closed-loop vector of the
asynchronous motor, you need to manually input the encoder direction. For synchronous motors, the
motor back EMF F05.15 should be set after the static learning is completed. If the control mode selects
the closed loop vector, whether it is static learning or dynamic learning, the synchronous motor will
rotate at a lower frequency for several weeks to learn the coding. Angle parameter.
Since the motor parameters are displayed in the form of standard values, it is not recommended to
manually input the motor parameters. In most cases, static learning can be run to run the open-loop
vector. Under the control of vf, learning the motor parameters will further optimize the automatic torque
boost and slip. Compensation function.
Before starting self-tuning, make sure that the motor is in a stopped state, otherwise self-tuning cannot
be performed normally.
When [F05.20] is set to "1", if overvoltage occurs during the self-tuning process and the overcurrent
fault occurs, the acceleration/deceleration time can be extended appropriately [F00.14, F00.15].
If the inverter self-tuning is unsuccessful, report E.TE1 failure.

AC300 Series Vector Control Inverter Manual
While synchronous motor control is valid, the initial position of the motor rotor can be obtained when starting by the
poles searching function. Under the closed-loop VC control, if the motor coder has not self-tuning the initial position,
then the start initial position can be obtained by this function. Under open-loop control, obtaining the initial position
guarantees the motor has a big force and no REV running while starting.
For synchronous closed-loop control using ABZ coder, the motor poles is unknown before detecting Z pulse.Hence, it
is suggested to turn on the poles searching function to guarantee the stable start process and no REV running.
