Hi guys, thanks for your attention.
The drive fails when is close to decelerate (its a roller conveyor for pallets), I tried increasing dec time but its the same.
I thought to acquire a braking resistor and the V20 braking module but definitively I have no space in the electric panel.
Yesterday I changed P1254=0 (no auto regulation of Vdc_max) and it worked but just during 1 or 2 hours, after that it continued to fail.
Any help is welcome.

Hello
The braking resistor can be installed in a side of the electric panel not inside
I think the better option is a breaking resistor if the dec time fails.
Check the following:
The Vdc regulator must be enabled
(P1240) and correctly parameterized.
