6. HOW TO USE INDEXER
The following item is the same as that of MR-J4-_A_-RJ servo amplifiers. Refer to the section of the detailed
description field for details. "MR-J4-_A_" means "MR-J4-_A_(-RJ) Servo Amplifier Instruction Manual".

6.1 Startup

6.1.1 Power on and off procedures

(1) Power-on
Switch power on in the following procedure. Always follow this procedure at power-on.
1) Switch off SON (Servo-on).
2) Make sure that ST1 (Forward rotation start) is off.
3) Switch on the main circuit power supply and control circuit power supply.
The display shows "C" and 2 s later shows data.
(2) Power-off
1) Switch off ST1 (Forward rotation start).
2) Switch off SON (Servo-on).
3) Switch off the main circuit power supply and control circuit power supply.
Item
Switching power on for the
first time
POINT
In the absolute position detection system, rotating the shaft one revolution or
more during power-off may erase a home position. Therefore, do not rotate the
shaft one revolution or more during power-off. When a home position is erased,
[AL. 90 Home position return incomplete warning] will occur. Then, execute the
home position return again.
The indexer method cannot be used in the fully closed loop system and linear
servo system. The combination of the indexer method and fully closed loop
system/linear servo system triggers [AL. 37 Parameter error].
