App. 7 Using the neutral point of a 3-phase 400 V AC class power supply for inputting a 1-
phase 200 V AC class power supply
CAUTION
Do not input a 3-phase 400 V AC class power supply directly to the 200 V class
servo amplifier. Otherwise, it may cause a malfunction.

You can use the neutral point of a 3-phase 400 V AC class power supply to input a 1-phase 200 V AC class
power supply to the servo amplifier.
If necessary, use a step-down transformer to decrease the power supply voltage to 200 V AC to 240 V AC.

2. 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-JE-200A servo amplifier's.
