(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?
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.
1)
Set [Pr. PL09 Magnetic pole detection voltage level] to "10" (guide value).
Execute "Forward CCW rotation" or "Reverse rotation" with "Positioning CW 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)
Turn "On (up)" the test operation select switch (SW2-1) of the servo amplifier, and then cycle the
power of the servo amplifier.
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)
Turn the servo amplifier power off and on again.
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 turn off the
servo amplifier power, and then
turn on the power again.
Turn the servo amplifier power
off and on again.
Reset the alarm or turn off
the servo amplifier power, and
then turn on the power again.
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.
