Remedy
Check the specifications of the
external encoder and correct the
values set for the External Encoder
Resolution (3901 hex) and External
Feedback Pulse Direction Switching
(3326 hex).
Increase the value set for the
Magnetic Pole Position Estimation
Force Command Time (3922 hex) or
Magnetic Pole Position Estimation
Force Command (3923 Hex) object.
If the axis has a large unbalanced
load or friction, the magnetic pole
position estimation function cannot be
used.

Prevention
Set the External Encoder Resolution
(3901 hex)/External Feedback Pulse
Direction Switching (3326 hex) values
according to the specifications of the
external encoder.
If the motor is subjected to a large
load or resistance, increase the
Magnetic Pole Position Estimation
Force Command Time (3922 hex) or
Magnetic Pole Position Estimation
Force Command (3923 hex) value.
