VMC1300 spindle doesn't spins

Post by IFTO-Brazil » Wed 25 Apr , 2018 22:29 pm

Machine was running correctly but when we started a new milling spindle didn't turn.
It did just about 90 degrees turn and stopped.
We disconnect servomotor (BALDOR) from spindle and it still happens which means problem is between electrical command or encoder or servomotor.
We are planning check each one meanwhile we would like to know if someone here had this problem and how it was solved.
Best regards

Does the ABB spindle drive have a green/red led on the top right & what status is it without the spindle being asked to run & with it being asked to run?

When machine is turned on led flashes green and red alternately during a while then stops with red on.
At first run command green led lights on but spindle didn't run.
As we turn off run command red led lights on.
After second run command red led flashes 5 times continuously (5 flashes + pause), even after stop command.

according to the sheet I have 5 flashes is "Feedback Trip". It may be worth unplugging the encoder from X& on the drive unit & plugging back in. You could also check that the connection at the spindle motor has not come loose if that does not work.
