6.2.4 Motor parameter autotuning and motor initial angle measuring
If you use a motor exclusive from the motor model table in section 5.2.5, perform motor
parameter autotuning first. The procedure is as follows:
1.
Set motor parameters.
In the setup menu on the LED panel, set F070 (Motor rated voltage), F071 (Motor rated
current), F072 (Motor rated rated rotation speed), F073 (Motor rated frequency), F074 (Motor
back-emf), and F075 (Motor temperature sensor).
2.
Enable the diagnosis function.
Set E13 to ON.
3.
Motor parameter autotuning
Perform motor parameter autotuning.
0: Disable Motor parameter autotuning is disabled.
1: Static If the motor back-emf has been obtained, but the motor does not rotate during
measuring, you can perform the autotuning without opening the relief valve.
2: Dynamic It is used if the motor back-emf is not obtained, while the motor rotates at high
speed during measuring. It is recommended to open the relief valve. With-load measuring
affects the accuracy of motor parameter measuring and the control effect. In addition, high
voltage is present in the oil path, which causes safety risks.
When autotuning starts if the setup is completed, the LED displays "― ― ― ― ― ―". When
autotuning is completed, the LED displays 0.
If the drive reports an alarm during testing, find out the cause, handle the problem, and then
continue the autotuning.
Set parameters on the LED:
4.
Measure the motor initial angle.
If you have completed motor parameter autotuning, you do not need to measure the motor
initial angle.
Set parameters on the LED:
When the initial angle measuring menu is accessed, the LED displays "READY". If you press
