Hello,
At the university I'm responsible for a KR15 robot with a KRC2 controller. Since last friday, the controller won't boot. The cabinet fan turns on, the 24V rail is present, also at the input of the power supply of the PC, yet the PC refuses to start.
Where and how to start debugging? In the documentation of the KRC2 I found something about some status LED's on the upper right unit in the controller cabinet. yet it's unclear what the current status is trying to tell. LED 1 (Red) is off, LED2 (green) is blinking at 1Hz.
Also the status leds on the motor drives are blinking (red LED burns continuously, green LED linking at 0.5Hz approx.)
Thanks
