At the Servo Drive, you need to adjust the current loop gain.
Using the Current Response Auto-adjustment (3912 hex) allows the Servo Drive to automatically set
the calculated value based on the Motor Inductance and Motor Resistance data.
To use the Current Response Auto-adjustment (3912 hex), you must set also the Motor Inductance
(3908 hex) and Motor Resistance (3909 hex).
The magnetic pole detection function detects the positional relationship between a magnetic pole and
an external encoder.
This Servo Drive offers the following two types of magnetic pole detection:
•
Magnetic pole position estimation method
•
Magnetic pole position restoration method
z
Magnetic Pole Position Estimation Method
In Magnetic pole position estimation method, the position of each magnetic pole is estimated
automatically at the first Servo ON after you turn ON the power supply.
The estimated pole position data will be effective until you reset the power supply. After resetting the
power supply, the Servo Drive will perform magnetic pole detection again at the first Servo ON.
