Good morning everyone, I'm with an ABB IRB6400 M97 presenting a different problem. At the time of moving the robot, the button motors on is blinking and the contactor does not stay on, making it impossible to move the robot.
Has anyone ever experienced this?

No (error) messages on the pendant ?

When the motor light blinks rapidly, it is indicating that the rev counters for one or more axes has been lost. You should check your error logs in service to see what else is wrong.

No (error) messages on the pendant ?Only:
20031 - Axis not calibrated
39103 - Mains missing
20207 - Backplane enable open
10012 - Guard stop State39103 - Incoming voltage to DC-link too low, drive system 1
Check voltage from motor on contactor. Replace dc-link -

Time to break out the M97 Control circuit diagrams and figure out why voltage is not getting to the DC-Link (rectifier).

Have you lost a phase of your incoming 480v?

Have you lost a phase of your incoming 480v?Our electrical network works with 220 V or 380 V

OK, so have you lost a phase of your incoming mains?

Hello,
Have you had success in fixing your problem.
I attach picture of M97 controller with jumpers inserted to enable

Most of the time, the DC-Link Too Low fault comes from the circuit breaker on top of the transformer being tripped This happens to me when I pull amplifiers and bump the breaker.

Boa tarde.
Vou escrever minhas diretrizes aqui. Para resolver meu problema, bastou trocar um dos contatores K2 Motor On, localizado dentro do quadro elétrico, acima do emergência de emergência.

Glad you fixed it, hopefully back in 2019.
Additional troubleshooting info:
If this was an intermittent fault, I test K1 & K2 with 18-20V on the coils and tap lightly on the side to see if they drop out. They usually hold at the lower voltage if they're good, weak ones will not.
