Hi,
Again we have problem with our QT15N. Our inverter displays an error after turning on the power. It's E7 alarm. But when we turn on the main panel, it's ready to work (shows "r 0"), but it doesn't supply power to the spindle motor. Main panel shows only alarm 128 Emergency stop.

Adds a video to clarify the situation:

If you check under diagnos screen, is there any other alarm then 128?
You should have 204 if there is a problem with spindle drive.

(I think you have a FR-SF drive and not a FR-SE)
 
Yes you are right, its FR-SF. Its T32-2 and there is only one alarm on diagnos. E7 is NC Emergency. I will check these leds as soon as I can.
 
So, there are 2 LEDs on the power supply SF-PW.
Led 1 (green) and led 2 (orange)

On the SF-CA card there are just Led 2 (orange), When the main panel is switched on, the LED 10 (orange) lights up and after a while turns off.

Also I saw there is 56 alarm on my servo drive, look at the video:
YouTube
 
Manual says that:
LED2 on SF-CA card - Lights when the base of the inverter/converter transistor
cuts off.

Any ideas?
 
It looks like the inverter has lost parametrs. You know where I can get them or someone will share theirs with me? Inverter is FR-SF-2-18.5KP-BCK and the motor is SJ-18.5BW4
