5. OPERATION AND FUNCTIONS
5.2.3 Setting of the magnetic pole detection voltage level
Set the magnetic pole detection voltage level with the parameter No.PS09 (magnetic pole detection voltage
level).
(1) Guideline of parameter settings
Set the parameters referring to the following table.
Parameter No. PS09 setting value
(Guide value)
(Servo status)
Small
Medium Large
(Less than 10 (Initial value) More than 50)
Thrust at operation Small Large
Overload, overcurrent alarm
Not frequently
occurred
Frequently occurred
Magnetic pole detection alarm Frequently occurred
Not frequently
occurred
Magnetic pole detection accuracy Low High
(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), overvoltage (33), 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.
(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), overvoltage (33), 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), overvoltage (33), 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.

Existence or nonexistence
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.
Here, the final setting value of the parameter No.PS09 is set to 49 (the setting value at the occurrence of
the overload and overcurrent alarm = 70
0.7).
