Lathes with VFDs

[Gordon Prill]

I just bought a Laguna 1836. I like it alot, but have a few questions about the VFD. It's located on the back of the headstock and everything I have read about them is it's important to keep the dust out it. I put a piece of metal window screen over to keep the big shavings out of it, but the fine dust will still get in there, yet I don't want to restrict the airflow. Any better solutions? Also the VFD does not shut off even when I hit the emergency stop. I don't see any reason to have it on overnight or if I don't get out to the shop for a few days. I just unplug it every night. Is this normal. Thanks

I have a Jet 1642-2hp. I always disconnect when I leave the shop. I am more concerned about lightning strike and/or power surge.

Many lathes are made with the VFD exposed; just blow the dust out once in a while. I unplug mine when not in use, like Harold I worry about power surges.
