Magnet Pole Search Error Detection Selection
0 or 1
0
0: Disabled
After searching for the rotor pole position one time, the drive starts using the detected rotor position. If the detected
position is wrong, an error occurs when the drive attempts to run the motor. The initial pole search takes approximately
1.5 s.
1: Enabled
The rotor pole position search is executed multiple times. The drive starts using the detected rotor position only if there is
no difference between the search results. Otherwise a dv8 error will be output. The initial pole search takes
approximately 1.5 to 5.0 s.
