Mod Light and Net Light off means no power. If you have for sure verified with a meter you have power, then the drive has failed
Manual, Chapter 7
Swap the drive for a new oneThe drive is on i have power coming in
If I'm not mistaken, the LCD display is driven by control power, same as the LEDs. The LCD is on. Line Power would be for the motor derivative power. I know that's how it is on 6500 and 5700 common bus racks....not sure about the 5500.Keep in mind that control power is separate from line power. I've seen this once before where a circuit breaker popped. Maintenance thought the drive died...
I just flipped the circuit breaker back on, asked them if this is how it should be? Yep... they got a bill.
Yes, K5300-K5500 have separate 24vdc control power and not line power like others that derive power from line. Control power and line power are separate issues. If either goes, nothing happens. If control power works, you get blinky lights on the control module.
In this situation, the control module could be toast, (in correct context) but I would at least check it.
