(4) Magnetic pole detection method setting

POINT

In the following cases, set the magnetic pole detection method to the minute

position detection method.

When a shorten travel distance at the magnetic pole detection is required

When the magnetic pole detection by the position detection method is not

completed

Set the magnetic pole detection method using the first digit of [Pr. PL08] (Magnetic pole detection

method selection).

[Pr.PL08]

⏛ᭂᬌ಴ᣇᴺߩㆬᛯ

(5) Setting of the magnetic pole detection voltage level by the position detection method

For the magnetic pole detection by the position detection method, set the voltage level with [Pr. PL09

Magnetic pole detection voltage level]. For the magnetic pole detection by the minute position detection

method, the voltage level setting is not required.

(a) Guideline of parameter settings

Set the parameters by referring to the following table.

[Pr. PL09] setting

(guide value)

Servo status

Small ĸ Medium ĺ Large

(10 or less (initial value) 50 or more)

Thrust at operation Small Large

Overload, overcurrent alarm Seldom occurs Frequently occurs

Magnetic pole detection alarm Frequently occurs Seldom occurs

Magnetic pole detection accuracy Low High

(b) Setting procedure

1) Perform the magnetic pole detection, and increase the setting value of [Pr. PL09 Magnetic pole

detection voltage level] until [AL. 50 Overload 1], [AL. 51 Overload 2], [AL. 33 Overvoltage], [AL.

E1 Overload warning 1], and [AL. EC Overload warning 2] occur. Increase the setting value by

five as a guide value. When these alarms and warnings occur during the magnetic pole detection

by using MR Configurator2, the test operation of MR Configurator2 automatically completes and

the servo-off status is established.

2) Specify the setting value that is an approximately 70% of the value set when [AL. 50 Overload 1],

[AL. 51 Overload 2], [AL. 33 Overvoltage], [AL. E1 Overload warning 1], and [AL. EC Overload

warning 2] occurred as the final setting value. However, if [AL. 27 Initial magnetic pole detection

error] occurs with this value, specify a value intermediate between the value set at [AL. 50

Overload 1], [AL. 51 Overload 2], [AL. 33 Overvoltage], [AL. E1 Overload warning 1], and [AL. EC

Overload warning 2] and the value set at the magnetic pole detection alarm as the final setting

value.

3) Perform the magnetic pole detection again with the final setting value.
