Hi,
Does exist a way for automatically shutting off the power of the motors at
the end of a program (something like Mxx), in order to avoid a self heating
of the motors ?
Thanks

No, not 'MIGHT'... it WILL. Been there, tried that... Not even servo
drives like that.
The best solution is to use drives which limit the idle current if
that is necessar

That's smart! I can't do that. The servo drives are doing it all
