Hello!

I have a Mitsubishi MR-J2S-100A, but I don't now what the input power should be.

One the plate:

INPUT: 5.0A 3PH+1PH200-230V 50Hz
3PH+1PH200-230V 60Hz

What does this mean? 3 phase is 380-400V? But there is L1, L2, L3 on the amplifier.

For your servo, it can be power up by 3 phase 200-230VAC, 50/60hz
For how to determine the 50/60z please refer to this link:

Thank you
 
I believe the 1PH they are referring to indicates the single phase supply voltage for the drive fan motor. They usually take one phase from the incoming power 3 phase and jumper it towards a separate terminal strip at the back underneath of the drive. This only feeds the fan,
