Refer to the following table for the Hall sensor signal patterns.
The Hall sensors are set according to the motor phase order selection in parameter
Pn080.1.
The processing at reading the Hall sensor signals has also been improved as follows.
If all the Hall sensor signals are 0 or 1 when the Hall sensors are connected, these
signals are ignored.
• However, if it occurs two times consecutively, the alarm A.C2 occurs.
• If U-phase edge does not activate two times continuously, it is not recognized as U-
phase edge.
• The angle for phase detection error is changed from 30 degrees to 40 degrees.
(The error of angle at installation is added to the maximum error of the angle when
the power is turned ON.)
