Assumed cause
The Magnetic Pole Detection
Method (3920 hex) was set to 3
(Magnetic pole position restoration
method), although magnetic pole
position estimation had never
been executed.
Cause and
correction
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.
Attached None

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).
Change the external encoder to an
absolute type.

Prevention
Before setting the Magnetic Pole
Detection Method (3920 hex) to 3
(Magnetic pole position
restoration method), once set the
object to 2 (Magnetic pole position
estimation method) and execute
magnetic pole position estimation.
Before setting the Magnetic Pole
Detection Method (3920 hex) to 3
(Magnetic pole position
restoration method), make sure
that your external encoder is an
absolute type.
