Motor Auto-tuning Setting
Auto-tuning Mode Function Code Setting Application
No operation F1-16 = 0
After motor auto-tuning is completed, the value of F1-16 is restored
to 0 automatically.
Static auto-tuning 1 F1-16 = 1
This mode is used when the back EMF of the motor is known.
The motor runs at a low speed during auto-tuning, and therefore,
the overow valve need not be opened.
Dynamic auto-tuning 1 F1-16 = 2 or 5
This mode is used when the back EMF of the motor is unknown.
The motor runs at a high speed during auto-tuning, and therefore,
the overow valve must be opened. With-load auto-tuning reduces
the accuracy of motor auto-tuning, affecting the system control
performance.
When F1-16 = 2, the motor rotating direction is clockwise when you
face the motor shaft. When F1-16 = 5, the motor rotating direction is
counterclockwise when you face the motor shaft.
Static auto-tuning 2 F1-16 = 3
This mode is used when the back EMF of the motor is known and
there is heavy load.
The motor runs at a low speed during auto-tuning, and therefore,
the overow valve need not be opened.
When wiring of the encoder and motor is correct but Err43 is
reported during static auto-tuning 1 or dynamic auto-tuning, use this
mode.
Dynamic auto-tuning2
F1-16 = 4 or 6
This mode enables you to obtain parameters such as back EMF
and the encoder installation angle within short time. The auto-tuning
accuracy is bad. This mode is used only for verifying whether the
motor is demagnetized.
The motor runs at a high speed during auto-tuning, and therefore,
the overow valve must be opened.
When F1-16 = 4, the motor rotating direction is clockwise when you
face the motor shaft. When F1-16 = 6, the motor rotating direction is
counterclockwise when you face the motor shaft.
