9.2 Startup [G] [WG]
■
Setting procedure
1.
Perform the magnetic pole detection, and increase the setting value of [Pr. PL09 Magnetic pole detection - Voltage level]
until [AL. 050 Overload 1], [AL. 051 Overload 2], [AL. 033 Overvoltage], [AL. 0E1 Overload warning 1], and [AL. 0EC
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 with MR Configurator2, the test operation of MR Configurator2 automatically
completes and the servo-off status is established.
2.
Set the value to approximately 70 % of the value which triggers [AL. 050], [AL. 051], [AL. 033], [AL. 0E1], and [AL. 0EC].
If [AL. 027 Initial magnetic pole detection error] occurs with this value, specify a value intermediate between the value set
at occurrence of [AL. 050], [AL. 051], [AL. 033], [AL. 0E1], and [AL. 0EC] 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, and make sure that the accuracy of the magnetic
pole detection is as required.

Setting example
In this example, set the final setting value of [Pr. PL09 Magnetic pole detection - Voltage level] to 49 (setting value at the alarm
occurrence = 70 × 0.7).
Setting of response performance and load to motor mass ratio by minute position
detection method
When using the minute position detection method, set the response performance with [Pr. PL17.0 Response selection] and
set the load to motor mass ratio with [Pr. PL17.1 Load to motor mass ratio/load to motor inertia ratio selection]. If the load to
mass of the linear servo motor primary-side ratio is unknown, perform the magnetic pole detection by the position detection
method, and then perform the auto tuning to set an estimated value.

Not occurring
While increasing the setting value of [Pr. PL09], carry out
the magnetic pole detection repeatedly.
An alarm has occurred when the setting
value of [Pr. PL09] is set to "70".
