14. USING A LINEAR SERVO MOTOR
3) After the completion of the magnetic pole detection, change [Pr. PL01] to "_ _ _ 0" (Magnetic pole
detection disabled).
After the magnetic pole detection, by disabling the magnetic pole detection function with [Pr. PL01],
the magnetic pole detection after each power-on is not required.
(4) Magnetic pole detection method setting
Set the magnetic pole detection method using the first digit of [Pr. PL08] (Magnetic pole detection
method selection).
(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.
(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.
