App. 10 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.

Note 1. 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-200B servo amplifier's.
