■Magnetic pole detection by minute position detection method
Magnetic pole detection
Check if LSP (Forward rotation stroke end), LSN (Reverse rotation stroke end), and EM2 (Forced stop 2) have been
turned on. Then, cycle the power of the servo amplifier or reset software.
Turn "ON (up)" the DIP switch (SW3-1).
Then, cycle the power of the servo amplifier or reset software.
Set [Pr. PL08.0 Magnetic pole detection method selection] to "4" (minute position detection method).
Set [Pr. PL01.0 Servo motor magnetic pole detection setting] to "1" (Magnetic pole detection at initial servo-on after
cycling the power).
Cycle the power of the servo amplifier or reset software.
Set the moment of inertia ratio for the direct drive motor with [Pr. PL17.1 Load to motor mass ratio/load to motor inertia
*2
ratio selection].
Execute "Forward rotation CCW" or "Reverse rotation CW" with "Positioning operation" in the test operation mode on
MR Configurator2. Set the travel distance to "0" at this time.
The magnetic pole detection is performed.
YES
Is the value of [Pr. PL17.0 Response
selection] the final value?
Has an abnormal sound or
vibration occurred during the
magnetic pole detection?
Have [AL. 032 Overcurrent],
[AL. 050 Overload 1],
[AL. 051 Overload 2], and
[AL. 0E1 Overload warning 1]
Is the travel distance during the
magnetic pole detection
Has [AL. 027 Initial magnetic pole
detection error] occurred?
Set [Pr. PL01.0] to "0" (Magnetic pole detection
*1
disabled).
Turn "OFF (down)" the DIP switch (SW3-1).
Then, cycle the power of the servo amplifier or reset software.
