2) Specify the setting value that is an approximately 70% of the value set when [AL. 50 Overload 1],
[AL. 51 Overload 2], [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. E1 Overload warning 1], or [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.

Magnetic pole detection
[Pr. PL09] setting value
An alarm has occurred when the setting
value of [Pr. PL09] is set to 70.
While increasing the setting value of [Pr. PL09], carry out the
magnetic pole detection repeatedly.
30 35 40 45 65 70
In this example, the final setting value of [Pr. PL09] is 49 (Setting value at the alarm occurrence = 70
× 0.7).
