I'm back, thanks for the replies.
The problem still not be solved!! the power cable for servos was made by myself, I'll go to check it.
First, the MADA is incorrect for sure!! Because the angle of axis rotation is not consistent with the display! For example, i travel axis6 for 90 degrees, it has turned more than 90 degrees
the robot's nameplate was lost, but it is certainly a KR210. I have the KSS software v4.1.5 and v4.1.7, and I have tried to install MADA
KR2210_SSCBS both, no one is correct!
The motors of axes 4-6 are 1FK6081, the motor of AXIS 3 is 1FK6101. Other motor's nameplate was gone.
I have checked the servo-file in MADA, the KSD16 file was for motor KK53N, it does not match 1FK6081. The KSD48 file is for 1FK6101
and 1FK6100.
I found there is a KR2210_SSCBC version which the appearance was same with my robot. but I can't find the MADA of KR2210_SSCBC in the KSS software!
the picture was found on the web, it looks same with mine. I can't fix this machine, any help appreciated!!
