Magnetic pole detection procedure
When using a controller manufactured by Mitsubishi Electric, the servo parameter setting values are
overwritten from the controller. Once magnetic pole detection is complete, note down the changed servo
parameter setting values, and set the same values in the controller.
Magnetic pole detection by 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 "0" (position detection method).
Set [Pr. PL01.0 Servo motor magnetic pole detection selection] to "1" (Magnetic pole detection at initial servo-on after cycling the
*1
power).
Cycle the power of the servo amplifier or reset software.
Set [Pr. PL09 Magnetic pole detection voltage level] to "10" as a guide value.
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 [Pr. PL09] the final value?
Has [AL. 027 Initial magnetic pole
detection error] occurred?
Have [AL. 032 Overcurrent],
[AL. 050 Overload 1],
[AL. 051 Overload 2],
and [AL. 0E1 Overload warning 1]
Set [Pr. PL01.0] to "0" (Magnetic pole detection disabled).
Turn "OFF (down)" the DIP switch (SW3-1).
Then, cycle the power of the servo amplifier or reset software.
End
*1 For the incremental system, the setting of [Pr. PL01] is not required.

Perform one of the following operations:
alarm reset, servo amplifier power cycling,
or software reset.
Cycle the power of the servo amplifier
or reset the software.
Perform one of the following operations:
alarm reset, servo amplifier power cycling,
or software reset.

Increase the value of [Pr. PL09] by five.
Set approximately 70 % of the value set for
[Pr. PL09] as the final setting value. If [AL.
027] occurs with this value, specify a value
intermediate between the value set at [AL.
0E1] and the value set at [AL. 027] as the
final setting value.
