(4) 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 parameter
No.PS09 (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.
Parameter No.PS09 setting value
(guide value)
Servo status
Small Medium Large
(Less than 10 (Default value) More than 50)
Torques required for 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 parameter No.PS09
(Magnetic pole detection voltage level) until Overload 1 (50. ), Overload 2 (51. ), Overload
warning 1 (E1. ), and Overload warning 2 (EC.1) 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 Configurator, the test operation of MR Configurator automatically completes and the servo-off
status is established.
2) Specify the setting value to approximately 70 of the value of Overload 1 (50. ), Overload 2
(51. ), Overload warning 1 (E1. ), and Overload warning 2 (EC.1) occurrence as the final setting
value. However, if Initial magnetic pole detection error (27. ) 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] occurrence and the value set at the magnetic pole
detection alarm occurrence, as the final setting value.
3) Perform the magnetic pole detection again with the final setting value.

Existence or nonexistence
Parameter No.PS09 setting value
Carry out the magnetic pole detection repeatedly while making
the setting value of the parameter No.PS09 larger. An alarm has occurred
when the setting value
of the parameter
No.PS09 is set to 70.
Magnetic pole detection
Overload and overcurrent alarm
In this example, the final setting value of parameter No.PS09 is 49 (setting value at the alarm
occurrence = 70 0.7).
