Would you think that the code could have anything to do with the drives faulting out i was running the machine everything was going well no problem then about @ line 7652 the drives faulted out coming out of an arc man what a pain.

Thanks Hood for all your help I have the machine running with out so far a drive fault out at 760 velocity and 950 on accel running the program at 350 MM per min i think that's not to bad.

They look like very nice drives but wow about $200 USD +S&H to the USA a bit steep is there anything made here in the USA that would do the same?

Thanks guys for the help looks like i will have to either slow the machine down or upgrade the drives well since money is the issue and i don't have a lot of work for the machine right now slow and steady it is thanks again.

The motors are 120 V DC this must be the why they have that spec, it may very well be that the drives are not capable of anything more then i am getting as they are rated for a max of 70 V the new ones are now rated for 80 volts originally the motor's were running at 100 V DC.
I did check with a transformer company and they advised me that there would not be much difference between the 50 V DC i was using and a new transformer with 70 V DC so i didn't change anything i really don't want to rewire the machine to use larger drives plus the money thing's being the way they are right now tight on cash.

Free rpm no load thats what it says on the label anyway, In no way dose the motor spin this rpm while the machine is running.

The motors run on DC 50 V the machine is a full size floor model 3 phase 5 hp , the servos are the Big MHO by baldor motion specs are 120 V/ DC, 500 in ozs torque, 39 amps, no load speed 31902 this is everything on the motor spec label other then the part #.

So if i lower the accel then can increase the velocity is that how it works ? so what is your thought on how low it should be and then how high would i go on the velocity ?
