Stroke limit disabled setting at magnetic pole detection
When performing a magnetic pole detection without LSP (Forward rotation stroke end) and LSN (Reverse rotation stroke
end), set [Pr. PL08.2 Magnetic pole detection - Stroke limit enabled/disabled selection].
Magnetic pole detection method setting
Set the magnetic pole detection method by using [Pr. PL08.0 Magnetic pole detection method selection].
In the following cases, set the magnetic pole detection method to the minute position detection method.
• When a shortened travel distance at the magnetic pole detection is required
• When the magnetic pole detection by the position detection method is not completed properly
For an absolute position detection system, set [Pr. PL01.0 Servo motor magnetic pole detection selection] to "1" (Magnetic
pole detection at initial servo-on after cycling the power). After the completion of the magnetic pole detection, change [Pr.
PL01.0] to "0" (magnetic pole detection disabled).
