15. USING A LINEAR SERVO MOTOR
(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
Magnetic pole detection
1) 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.
2) Set [Pr. PL08 Linear servo motor/DD motor function selection 3] to "_ _ _ 0" to set the magnetic
pole detection method to "Position detection method".
3) Set [Pr. PL01 Linear servo motor/DD motor function selection 1] to "_ _ _ 1" to enable "Magnetic
pole detection at first servo-on". (Note)
4) Cycle the servo amplifier power.
5) Set [Pr. PL09 Magnetic pole detection voltage level] to "10" (guide value).
6) 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.
The magnetic pole detection is carried out.
YES
Is [Pr. PL09] the final value?
Has [AL. 27 Initial magnetic pole
detection error] occurred?
Have [AL. 32 Overcurrent], [AL.
50 Overload 1], [AL. 51 Overload 2], and
[AL. E1 Overload warning 1]
occurred?
7) Set [Pr. PL01] to "_ _ _ 0" to set "Magnetic pole detection disabled". (Note)
End
Note. For the incremental system, the [Pr. PL01] setting is not required.
NO
YES
Reset the alarm or cycle the
servo amplifier power.
NO
NO
Cycle the servo amplifier power.
YES
Reset the alarm or cycle the
servo amplifier power.
15 - 12
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.
