(1) Magnetic pole detection method by using MR Configurator2
The following shows the magnetic pole detection procedure by using MR Configurator2.
(a) Magnetic pole detection by the position detection method
Have [AL. 32 Overcurrent], [AL. 50
Overload 1], [AL. 51 Overload 2], and
[AL. E1 Overload warning 1]
occurred?
1) Check that FLS (Upper stroke limit), RLS (Lower stroke limit), and EM2 (Forced stop 2) are on, and
then cycle the servo amplifier power.
Turn "On (up)" the test operation select switch (SW2-1) of the servo amplifier, and then cycle the
power of the servo amplifier.
Set [Pr. PL08 Linear servo motor/DD motor function selection 3] to "_ _ _ 0" to set the magnetic
pole detection method to "Position detection method".
Cycle the servo amplifier power.
6) Set [Pr. PL09 Magnetic pole detection voltage level] to "10" (guide value).
7) Execute "Positive direction travel" or "Negative direction travel" with "Positioning operation" in the
test operation mode on MR Configurator2. Set the travel distance to "0" at this time.
8) Set [Pr. PL01] to "_ _ _ 0" to set "Magnetic pole detection disabled". (Note)
2)

4)
5)
The magnetic pole detection is carried out.
Is [Pr. PL09] the final value?
Has [AL. 27 Initial magnetic pole
detection error] occurred?
Reset the alarm or cycle the
servo amplifier power.
Cycle the servo amplifier power.
Reset the alarm or cycle the
servo amplifier power.
Increase the value of [Pr. PL09]
by five.
Set an approximately 70% of the
value set for [Pr. PL09] as the
final setting value.
If [AL. 27 Initial magnetic pole
detection error] occurs with this
value, specify a value
intermediate between the value
set at [AL. E1 Overload warning
1] and the value set at [AL. 27
Initial magnetic pole detection
error] as the final setting value.

End
Set [Pr. PL01 Linear servo motor/DD motor function selection 1] to "_ _ _ 1" to enable "Magnetic
pole detection at first servo-on". (Note)
Note. For the incremental system, the [Pr. PL01] setting is not required.
