VFS5 FAN
Its been way to short a time for me to be back for help but I sure hope I can find some anyhow...
I have an arrow 1000 with 2100 control. This morning I started it up and hear a loud fan. Open the cabinet and its the spindle drive fan . I cleaned it up and it seemed fine, now its not working at all. Will this cause any problems elseware? I have no overtemp alarm but, I just started to get this overcurrent fault light on my x drive bds4 (and alarm 39-53) after about twenty minutes of running fine. Turn it off and refire and its fine for another 20 min. ??? I am going to pull the spindle drive and see if I can find a fan for it, but I am in deep here, I dont know where else to start.
Thanks for the help

The spindle drive fan should be a readily available unit. If you have trouble finding a replacement, let me know I may have one in stock.
But,...this shouldn't have anything to do with your x axis overcurrent fault. This is most commonly associated with motor or cable issue but can be drive as well.
When you say it ran for 20 minutes twice, did it fail at the same point in a program? If so, possibly a short in the cable that happens at that specific point.
Another thing to check is remove the cover over the x axis ballscrew coupling. If there is evidence of moisture, coolant is likely getting through the support bearings (which will fail because the grease washes out), and if the casting fills with coolant, it can get into the motor.

Re: VFS5 FAN
Thanks Maver1ck and Mike,
I ordered a new fan, it will not be here for a few days. I cant wait that long- so I removed the VFS5 and cleaned all the soot and gunk from the fan and the interior of the amplifier side (fins) . Removed the fan axle cover and oiled lightly. Put back together tested and it works for now. It has been in the machine all day and I have no overcurrent alarm at all. When the new one comes I will replace.
Thanks again. I am going to check those covers you guys are talking about too ,, now you got me worried .HA

Re: VFS5 FAN
If you kept the back door closed and replaced the gasket around the door and plugged any holes in the cabinet you would not get gunk in the fans as you described. You should think about adding an air conditioner to the electrical panel and closing off the upper and lower fan openings in the cabinet and disconnecting the cabinet fan. This has worked very well for my customers to reduce heat related problems with the machine and control. Fans do fail but should not be filled with oily greasy residue that stops them from working if the doors shut and air filters are kept clean. What about the heat exchanger fins in the drive, how do they look?? Just saying.
