The RSC has reported that its power is failing. Because a power failure on the RSC almost always causes it to stop communicating altogether (rendering it incapable of reporting the failure) this error message may be due to some other cause such as electrical noise at the RSC or within or around the arm signal cable. It is possible that the power lines to the RSC have an intermittent connection somewhere. On FireWire Robots this error indicates that a robot amplifier has detected an under- or over-voltage of its internal DC Bus. This may be due to AC power supply out of spec of 200-240V or a motion that is too hard or too fast for the payload of the robot.
