■Magnetic pole detection by minute position detection method
Magnetic pole detection
Check if LSP (Forward rotation stroke end), LSN (Reverse rotation stroke end), and EM2 (Forced stop 2) have been
turned on. Then, cycle the power of the servo amplifier or reset software.
Set [Pr. PC05.1 Test operation selection] to "1" (enabled).
Then, cycle the power of the servo amplifier or reset 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 setting] to "1" (Magnetic pole detection at initial servo-on after
cycling the power).
Cycle the power of the servo amplifier or reset 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.
YES
Is the value of [Pr. PL17.0
Response selection] the final value?
Has an abnormal sound or
vibration occurred during the
magnetic pole detection?
Have [AL. 032 Overcurrent],
[AL. 050 Overload 1],
[AL. 051 Overload 2], and
[AL. 0E1 Overload warning 1]
occurred?
Is the travel distance during
the magnetic pole detection
acceptable?
Has [AL. 027 Initial magnetic
pole detection error] occurred?
Set [Pr. PL01.0] to "0" (Magnetic pole detection
*1
disabled).
Set [Pr. PC05.1] to "0" (disabled).
Then, cycle the power of the servo amplifier or
reset software.
