I have an old DC-Servo Minertia Motor J03M-GG12, all I found on the net is, that Yaskawa have the same Number, so I believe that the Motor is originally Yaskawa. It have a Yaskawa Encoder DP8309136. But it seems that it use only 4 of the 5 cables, Black, white, red and green. Where can I find the maximum voltage and ampere the motor uses and which encodercable is used for In and output?
