Hello,
I need some help from you to see if i put my machine working.
It's a arrow 750 with kollmorgen drives
It's giving me the alarm 39-35 spindle not up to speed.
If i put up to 370 rpm it turns ok and i have checked the spindle rpm drift and it's only 2 rpm out!
Above that it does not turn and after some seconds gives me that alarm.
What i have checked:
Relays- All good even Cr22 cr_spdl_spd, It Have 24v also.
I opened the psr and the vds5.
On psr i found one track coming from the La signal broken and repair it and now it's ok.
On the vds5 i didn't found anything and i made the cable to conect to pc but my computers are too modern to install motion link plus( i'm waiting to find some friend with a old pc)
I also check the thermosthat at both psr and vds5 and both are ok.
Checked all the wirings comming from the C8 plug and are all ok.
I don't know were to search more!
Do you guys have any idea?
The psr gives red light fault when the error appears.
But if i turn off the machine and on it's all ok and up to 370rpm it runs ok.
I have a work that i need to finish and i only have this machine!
Hope you guys can help.
Thanks
