14. USING A DIRECT DRIVE MOTOR
(c) State transition of the servo amplifier display (3-digit, 7-segment LED) at the magnetic pole detection
When the magnetic pole detection with MR Configurator is normally executed, the servo amplifier
display (3-digit, 7-segment LED) shows the state as below.
14.4.3 Operation from controller
To configure the absolute position detection system by using the direct drive motor, the battery unit (MR-
BTCASE MR-BAT 8) and the absolute position storage unit MR-BTAS01 are required.
The direct drive servo can be used with any of the following controllers.
(1) Operation method
Positioning operation from the controller is basically performed like the MR-J3W- B servo amplifier.
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.
