Magnetic pole detection
Check that FLS (Upper stroke limit), RLS (Lower stroke limit), and EM2 (Forced stop 2)
are on, and turn the servo amplifier power off and on again.
Set the test operation select switch (SW2-1) of the servo amplifier to "Up", and turn the
servo amplifier power off and on again.
Set [Pr. PL08 Linear servo motor/DD motor function selection 3] to "_ _ _ 0" to set the
[Pr.PL08
"
magnetic pole detection method to "Position detection method"
Set [Pr. PL01 Linear servo motor/DD motor function selection 1] to "_ _ _ 1" to enable
[Pr.PL01
" ( 1)
"Magnetic pole detection at first servo-on".
Turn the servo amplifier power off and on again.
With [Pr. PL17 Magnetic pole detection - Minute position detection method - Function
( 2)
selection], set the load to mass of the linear servo motor primary side ratio. (Note 2)
Execute "Positive direction travel" or "Negative direction travel" with "Positioning operation" in the
"0"
test operation mode on MR Configurator2. Set the travel distance to "0" at this time.
The magnetic pole detection is carried out.
[Pr.PL17]
Is the response by the minute
position detection method of
[Pr. PL17] the final value?
?
NO
Has an abnormal sound or
vibration occurred during the
magnetic pole detection?
NO
Is the travel distance during
the magnetic pole detection
?( 3)
acceptable?
Acceptable
Set [Pr. PL01] to "_ _ _ 0" to set "Magnetic pole detection invalid". (Note)
End
For the incremental system, the [Pr. PL01] setting is not required.
2. If the load to primary-side linear servo motor mass 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
response by the minute position detection method in [Pr. PL17].
