    Here's a schematic of what's going on in the control panel:

    Rongfu round column mill VFD install.

    Thanks, Mike, I did see that part of the manual. First thing I did was a factory reset. Then I checked that value and it is, indeed, set to ‘no’. But it does restart if the 24v signal is present on LI1 upon power up. So I decided to go with momentary switches to be safe.

    Rongfu round column mill VFD install.

    The control box, which will reside above the spindle lock handle, will control all functions related to the drive. GIven the space constraints, a 2-wide, 3-up patten for the control buttons is best. I've chosen Schneider control buttons for this project, and I can't fit that arrangement in...

    Rongfu round column mill VFD install.

    I'm going to mount the VFD where the magnetic starter currently sits, with the control box in front, above the spindle lock. The VFD is wider than the magnetic starter, and the column crank will have to be moved outward to make this all fit. The stock crank handle looks like this: I fashioned...

    Rongfu round column mill VFD install.

    I've been reading through your thread, YYCHM; quite informative. I'm planning to mount my VFD and control panel onto the left hand side of the mill head, so aiming for as small a drive package as I can manage. Looks like everything will fit, and I've already made some of the custom...

    Rongfu round column mill VFD install.

    One detail that I noticed in my testing of the the VFD is that it will return power to the drive upon a power outage/restart. So if I use a simple toggle switch to control the motor power the drive can restart itself after a power outage, which is... less than desirable. So my plan will be to...

    Rongfu round column mill VFD install.

    The motor is currently controlled by a magnetic starter. There is a switch behind the starter to turn on/off the mist cooling system. The mist cooling system comprises the switch, a solenoid and the mist cooling block itself, as shown below. On the right side of the mill head is a switch...

    Rongfu round column mill VFD install.

    Here are the pieces I bought. The motor is a 2 HP, 240v, 3-phase Baldor motor, replacing my previous 1/5 HP 240v, 1-phase Princess Auto motor. The VFD is a Square-D (Schneider) Altivar 18, rated for 240V and 1.5KW (2 HP) that was surplussed from an industrial installation. Both pieces are well...

    Rongfu round column mill VFD install.

    I found a 3 phase motor locally on Kijiji and bought a surplus VFD on EBay. This thread will document the process of mounting them to my Rongfu round column mill.

    Round Column Mill DRO upgrade.

    Nope, everything is dry under the table. I thought of pulling the y-axis saddle and making a seal under the new cavity, but I don’t think there is any need to do so.
