Cause and
correction
Assumed cause Remedy Prevention
The Magnetic Pole Detection Method
(3920 hex) object was set to 3
(Magnetic pole position restoration
method), although the Magnetic Pole
Position Estimation had never been
executed.
Set the Magnetic Pole Detection
Method (3920 hex) to 2 (Magnetic
pole position estimation method) and
execute the Magnetic Pole Position
Estimation once.
Then, set the Magnetic Pole
Detection Method (3920 hex) to 3
(Magnetic pole position restoration
method).
Before setting the Magnetic Pole
Detection Method (3920 hex) object
to 3 (Magnetic pole position
restoration method), once set the
object to 2 (Magnetic pole position
estimation method) and execute the
Magnetic Pole Position Estimation.
The Magnetic Pole Detection Method
(3920 hex) was set to 3 (Magnetic
pole position restoration method)
when a non-absolute type external
encoder was used.
Change the external encoder to an
absolute type.
Before setting the Magnetic Pole
Detection Method (3920 hex) object
to 3 (Magnetic pole position
restoration method), make sure that
your external encoder is an absolute
type.
