7. Use a magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of
contacts) of 80 ms or less. Depending on the main circuit voltage and operation pattern, bus voltage decreases, and that

POINT
Connect the 1-phase 200 V AC to 240 V AC power supply to L1 and L3. One of
the connecting destinations is different from MR-J3 Series Servo Amplifier's.
When using MR-J4 as a replacement for MR-J3, be careful not to connect the
power to L2.
