■Magnetic pole detection by minute position detection method
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.
Set [Pr. PL08.0 Magnetic pole detection method selection] to "4" (minute position detection method).
Set [Pr. PL01.0 Servo motor magnetic pole detection selection] to "1" (Magnetic pole detection at initial servo-on
*1
after cycling the power).
Cycle the power of the servo amplifier. Alternatively, reset the software.
Set the load to mass of the linear servo motor primary-side ratio with [Pr. PL17.1 Load to motor mass ratio/load to
motor inertia ratio selection].
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 performed.
Is the value of [Pr. PL17.0
YES
Response selection] the
final value?
NO
Has an abnormal sound or
vibration occurred during the
magnetic pole detection?
NO
Have [AL. 032 Overcurrent],
[AL. 050 Overload 1],
[AL. 051 Overload 2], and
[AL. 0E1 Overload warning 1]
occurred?
NO
Is the travel distance during the
magnetic pole detection acceptable?
Acceptable
Has [AL. 027 Initial magnetic
pole detection error] occurred?
NO
Set [Pr. PL01.0] to "0" (Magnetic pole detection
*1
disabled).
End
*1 For the incremental system, the setting of [Pr. PL01] is not required.
*2 If the load to mass of the linear servo motor primary-side ratio is unknown, perform the magnetic pole detection by the position detection
method, and then perform the auto tuning to set an estimated value.
*3 For the magnetic pole detection by the minute position detection method, the maximum travel distance at the magnetic pole detection
must be 0.5 mm or less. To shorten the travel distance, increase the value of [Pr. PL17.0].
YES Set the value of [Pr. PL17.0] decreased by two
as the final setting value.
Decrease the value of [Pr. PL18 Magnetic pole detection
YES
- Minute position detection method - Identification signal
amplitude] by five.
Not acceptable
Increase the value of [Pr. PL17.0] by one.
*3
Is the setting value of [Pr. PL17
YES
Magnetic pole detection - Minute
position detection method - Function
selection] correct?
Set [Pr. PL08.0] to "0" (position detection method).
NO
YES
