The servo amplifier display (3-digit 7-segment LED) shifts as shown below when the magnetic poles are 
detected properly using MR Configurator.

4.3 Operation from the controller 

When establishing the absolute position detection system, battery (MR-J3BAT) and the absolute position 
storage unit is required. 
The direct drive servo can be used in combination with the following controllers.

Note. Refer to the manual of the each servo system controller for the software version and other 

details.  

 
4.3.1 Operation method 

The positioning operation from the controller is basically the same as that of MR-J3- B. 
For the system, using the incremental system, however, the magnetic pole detection is automatically performed 
at the first servo-on after turning the power on. For this reason, when performing the positioning operation, 
configure the sequence which surely confirms the servo-on status as the inter lock condition of the positioning 
command. 
Also, some parameter settings and home position return varies depending on types of controllers.
