(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.

Set [Pr. PL09 Magnetic pole detection voltage level] to "10" (guide value).

Execute "Forward rotation" or "Reverse rotation" with "Positioning operation" in the test operation

mode on MR Configurator2. Set the moving distance to "0" at this time.

Set [Pr. PL01] to "_ _ _ 0" to set "Magnetic pole detection invalid". (Note)

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 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 valid". (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]

and the value set at [AL. 27 Initial

magnetic pole detection error] as

the final setting value.

YES

Magnetic pole detection

End

Note. For the incremental system, the [Pr. PL01] setting is not required.

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. PL01 Linear servo motor/DD motor function selection 1] to "_ _ _ 1" to set "Magnetic pole

detection always enabled". (Note)

Execute "Forward rotation" or "Reverse rotation" with "Positioning operation" in the test operation

mode on MR Configurator2. Set the travel distance to "0" at this time.

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.

Set [Pr. PL01] to "_ _ _ 0" to set "Magnetic pole detection disabled". (Note)
