Note 1. The battery (option) is used for the absolute position detection system in the position control mode.
2. The power factor improving AC reactor can also be used. In this case, the power factor improving DC reactor cannot be used.
When not using power factor improving DC reactor, short P1 and P2.
3. 1-phase 200 V to 230 V AC power supply may be used with the servo amplifier of MR-J3-70T or less.
For 1-phase 200 V to 230 V AC, connect the power supply to L1/L2 and leave L3 open. Refer to "section 3.1 Function
Comparison Table (3)" for the power supply.
