・ When the incremental encoder is used too with No.2229#0(ABSEN)=1, the result of pole
positon detection is memorized to No.2139 (AMR offset) after the pole position detection is
completed and one rotation signal in encoder is caught. This suppresses change of the torque
constant by the variation in pole position detection.
Note
・ When the incremental encoder is used, the result of pole positon
detection is memorized just after one rotation signal in encoder is caught.
Accordingly, even if the pole position detection is executed, the result of
pole position detection is not memorized when the power is turned off
before one rotation signal in encoder is caught
・ When the incremental encoder is used, the result of pole position
detection memorized in the parameter No.2139 (AMR offset) is effective
in servo control after one rotation signal in encoder is caught.
Accordingly, the torque constant may be changed by the variation in pole
position detection until one rotation signal in encorder is caught.
