2.2kw Vfd/3 Phase 3hp Motor

This is how I mounted my VFD, maybe not the best but it works for me. I'm used to reaching into this area to operate the motor switch so it seemed logical.

How high is that. That is where the switch is located now but it seems high to be comfortable. My little mill I mounted the start/stop switch under the table. I can't remember if that was where it already was out just where I put it but I remember having to remount it & I know I had to drill a new hole in the casting to move the wires.

It's about 6ft off of the floor maybe a bit more. It's the normal location for most full size knee mill switches. After about 45 years of running these type of machines, for me it just seems natural to reach into that area. It's really a matter of what you are used to.

 

[kingmt01]

I agree. Maybe I spent to much time making things more ergonomic. I like to be comfortable as convent when I'm working. Most of the controls are reaching up anyways so that one isn't that big of a deal.

Well my VFD seems to be held up in NY for some reason. Tracking has showed it there for a week.

I got my VFD today. I'm thinking about hooking the rotary switch. I'm a little cloudy on the instructions.







So close DCM & FOR to run it forward. Close DCM, FOR, & REV to run it in reverse?

 

[JimDawson]

DCM+FOR = FOR
DCM+REV = REV
DCM+ . . = OFF

 

[kingmt01]

Thanks. The instructions are pretty good but that was confusing.

Two more questions for now. Is frequency tracking a good thing?

The long slot at the bottom has a long rubber piece


Are you just supposed to poke the wire through that rubber?

 

[JimDawson]

I think frequency tracking refers to controlling the VFD output with a separate external device. Probably not useful in most applications, would be useful to slave the VFD to another motor, like in a multiple belt conveyor system to keep them running at the same speed.

Yes, you just slit the grommet and stuff the wires through, a crappy system but common
