15. USING A DIRECT DRIVE MOTOR

15 - 8

(b) Magnetic pole detection by the minute position detection method

Is the moving distance

during the magnetic pole

detection acceptable?

(Note 3)

Turn the servo amplifier power off and on again.

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. PL08 Linear servo motor/DD motor function selection 3] to "_ _ _ 4" to set the magnetic pole

detection method to "Minute position detection method".

The magnetic pole detection is carried out.

Is the response of the

minute position detection method

of [Pr. PL17] the final value?

Has an abnormal sound or

vibration occurred during the

magnetic pole detection?

Decrease the response of the minute

position detection method of [Pr. PL17] by

two as the final setting value.

Increase the response of the minute

position detection method of [Pr. PL17] by

one.

Not

acceptable

Magnetic pole detection

End

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

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

detection always valid". (Note)

Set the load inertia moment ratio of the direct drive motor with [Pr. PL17 Magnetic pole detection -

Minute position detection method - Function selection]. (Note 2)

Note 1.

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

If the load to direct drive motor inertia ratio is unknown, perform the magnetic pole detection by the

position detection method, and then perform the auto tuning to set an estimated value.

For the magnetic pole detection by the minute position detection method, the maximum rotation angle at

the magnetic pole detection must be five degrees or less. To shorten the travel distance, increase the

response by the minute position detection method in [Pr. PL17].

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.

Is the response of the minute

position detection method set

by [Pr. PL17] finalized?

Is the travel distance

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