Magnetic pole detection
Check that LSP (Forward rotation stroke end), LSN (Reverse rotation stroke end), and EM2 (Forced stop 2) are on, and then cycle
the servo amplifier power. Alternatively, reset the software.
Turn "ON (up)" the DIP switch (SW3-1), and cycle the power of the servo amplifier or reset the 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
power).
Cycle the power of the servo amplifier. Alternatively, reset the 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.
Is [Pr. PL09] the final value?
Perform one of the following operations:
alarm reset, servo amplifier power cycling,
or software reset.
Has [AL. 027 Initial magnetic pole
detection error] occurred?
Increase the value of [Pr. PL09] by five.
Have [AL. 032 Overcurrent],
[AL. 050 Overload 1],
[AL. 051 Overload 2],
and [AL. 0E1 Overload warning 1]
occurred?
Cycle the power of the servo amplifier
or reset the software.
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.
Perform one of the following operations:
alarm reset, servo amplifier power cycling,
or software reset.
Set [Pr. PL01.0] to "0" (Magnetic pole detection disabled).
