How to recognize wires of DC motor ?

[small_chip]

I've got a Hitachi DC servo motor which has 5 wires (besides 2 other wires in order to supply power for motor): red,green, white,yellow and black.
I guess: red wire = power & green wire = GND for encoder, white wire = A phase encoder, yellow = B phase encoder and black wire = index signal in order to determine completion of a revolution! is this right ?

What is model number of that motor?

Did you look in datasheet?

The VCC and GND is easily known, using oscilloscope you can fin out EnA, EnB which have 90 degrees difference. let me know if you have a problem.
