I am a student working an old S10 robot with an R-J Controller and I am now having the problem of SRDY on axis 2. I had to reload the software on the robot, but before I reloaded the software the robot was working fine. The controller has 1/4, 2/5, and 3/6 axis on the same amps. I have tested the 100A wire to 100B wire voltage and it was fine. I also tested the wire from the amp to the axis control PCB and it was fine. I also changed the Servo Interface with another on the same axis control PCB and the problem stayed at the same axis. The robot is not mastered because of the reload of the software, could that be the cause? I don't believe it is the amp, as again, it worked before the software reload. Any feedback you have would be nice, thanks in advanced.
