4.2.4 Setting the magnetic pole detection voltage level of the position detection method
Set the voltage level in parameter No.PS09 (Magnetic pole detection voltage level) to perform magnetic pole
detection with the position detection method. Voltage level setting is not required when detecting magnetic poles
by the minute position detection method.

(2) Setting procedure
(a) By carrying out the magnetic pole operation, make the setting of parameter No.PS09 (magnetic pole
detection voltage level) larger until the overload 1 (50), overload 2 (51), overload warning 1 (E1) and
overload warning 2 (EC) occur. To get a rough idea, make it lager in "5". When these alarms and
warnings occur during the magnetic pole detection by MR Configurator, the test operation of MR
Configurator is automatically completed and the servo-off status is established.

warnings occur during the magnetic pole detection by MR Configurator, the test operation of MR
Configurator is automatically completed and the servo-off status is established.
(b) Set the final setting value to approximately 70% of the value which is set at the occurrence of the
overload 1 (50), overload 2 (51), overload warning 1 (E1) and overload warning 2 (EC). However, in the
case where the initial magnetic pole detection error (27) occurs with this setting value, set the final
setting value to the value intermediate between the setting value at the occurrence of the overload 1
(50), overload 2 (51), overload warning 1 (E1), overload warning 2 (EC) and the setting value at the
occurrence of the magnetic pole detection alarm.

(c) Carry out the magnetic pole detection again with the final setting value.
