    Just an update for anyone following, or any future googlers - I got the brake wired and working properly. The VFD power input is 220v. I wired the same circuit to the brake, and left the original...

    L0 spindle so the brake actually helps in this case. Also, the drum switch itself has Fwd/N/Brake/N/Rev, so by default I would have a neutral position where the brake is off but the motor is not...

    Ignoring any VFD wiring, I would wire 120VAC to the drum switch input, and the output (closed circuit when in middle position) would go to the brake, with...

    Ok it's starting to make a little more sense - I have the VFD and braking resistor, and intend to do as described and have it stop at a reasonable rate in neutral. So ultimately I just need a DC...

    Unfortunately I haven’t been able to locate a wiring diagram. It’s a 50-60’s era machine. I’ll do my best to get more info.

    Power switch to vfd, and relay output makes sense. But what then? DC...

    It's a 3hp. My intention is to use a VFD to run the motor. It's currently in it's factory state, ready to be moved into place and wired up.

    Still factory wired, minus a disconnected coolant pump (no intentions of reconnecting).

    Unfortunately no 3-phase, hence the need for the VFD.

    An RPC is an option too but I'd much rather have the VFD and no mechanical brake, than an RPC and factory control.

    Leblond Spindle Brake with VFD

    I am fixing to hook up a 15" Regal to a VFD. I know I can ramp down decel, and/or add a braking resistor, but I would like to know how difficult it would be to hook up the factory spindle brake to...
