Motor "ON" during normal operation displays "U--" when it was working fine
<or Motor not yet ON>

U1 - at this point the Motor is running but displaying "U1" instead of "U--"

When the Load or Speed is increased, the ampere increase from 1A (no load just the motor and the gearbox)
to 3A(minimal load) at 400VAC (input of the Veritron Controller), the motor then stops and display F10.
The usual ampere of this Motor is above 10A at 400AC using a Clamp Meter from the input of Veritron.

The Motor will run up to 2.8A or approx 95% of max speed/RPM w/ gearbox engaged but no other load.
But if you max the speed w/ gearbox w/out other loads, the amp reaches 3A and the motor stops.
If the gearbox is disengaged, the amp reading drops to around 1A at 400VAC and the motor runs up to max speed continuously.

F10 = Firing monitor: 1 thyristor is not firing
F11 = Pulse Firing Section not in synchronism for more than 500ms
F12 = Line under voltage for more than 500ms
