3) Perform the magnetic pole detection again with the final setting value.

Alarm
Magnetic pole detection
[Pr. PL09] setting value
An alarm has occurred when the setting
value of [Pr. PL09] is set to 70.
While increasing the setting value of [Pr. PL09], carry out the
magnetic pole detection repeatedly.
30 35 40 45 65 70
In this example, the final setting value of [Pr. PL09] is 49 (Setting value at the alarm occurrence = 70
× 0.7).
15.3.3 Operation from controller
To configure the absolute position detection system by using the direct drive motor, the battery unit (MR-
BAT6V1SET) and the absolute position storage unit MR-BTAS01 are required.
(1) Operation method
For the incremental system, the magnetic pole detection is automatically performed at the first servo-on
after the power-on. For this reason, when performing the positioning operation, create the sequence
which surely confirms the servo-on status as the inter lock condition of the positioning command.
Also, some parameter settings and the home position return differ according to the controller type.
