(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?

4)
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
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.
Set [Pr. PL08 Linear servo motor/DD motor function selection 3] to "_ _ _ 0" to set the magnetic
pole detection method to "Position detection method".
Set [Pr. PL01 Linear servo motor/DD motor function selection 1] to "_ _ _ 1" to set "Magnetic pole
detection always enabled". (Note)
Cycle the servo amplifier power.
Set [Pr. PL09 Magnetic pole detection voltage level] to "10" (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.
Set [Pr. PL01] to "_ _ _ 0" to set "Magnetic pole detection disabled". (Note)
Note. For the incremental system, the [Pr. PL01] setting is not required.
