12. ABSOLUTE POSITION DETECTION SYSTEM

12.1.2 Restrictions

The system cannot be configured under the following conditions. Additionally, test operation cannot be
performed in the absolute position detection system. To perform test operation, select incremental system in
[Pr. PA03].
(1) Speed control mode and torque control mode
(2) Control switch-over mode (position/speed, speed/torque, and torque/position)
(3) Stroke-less coordinate system, e.g. rotary shaft, infinitely long positioning
(4) Changing electronic gear after home position setting.
(5) Using alarm code output.
(6) Using incremental value command method ([Pr. PT01] = "_ _ _ 1").
To configure absolute position detection system in incremental value command method, specify the
incremental value command with the sub function of the point table or the command in the program. For
details, refer to 4.2.2 and 5.2.2 of "MR-J4-_A_(-RJ) Servo Amplifier Instruction Manual (Positioning
Mode)".
