Operation From Controller - Mitsubishi Electric MR-J4-10B(-RJ) Instruction Manual

15. USING A DIRECT DRIVE MOTOR

15.3.3 Operation from controller

To configure the absolute position detection system by using the direct drive motor, the battery 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.
(2) Servo system controller setting
The following parameters will be enabled by cycling the servo amplifier power after the controller writes
the parameters to the servo amplifier.
