FM3 practical foot switch use

So I may get my hands on an FM3 shortly and I'm curious about the foot switch situation.

On my Helix I have 8 foot switches instantly available to me, so I have various snap shots assigned to them. During a song I can jump on any of those
foot switches instantly. In an average song preset I can probably get away with using 4 or 5 scenes on an FM3 so how am I going to make those scenes
as instantly available as what I'm used to - without and FC6? I don't want the extra foot controller at the moment due to the expense.

I know plenty of you guys are using an FM3 to play live, so how do you arrange the switches in such a way that you can get quick access
to multiple scenes when you've only got three switches? Do you just limit yourself to 3 scenes per song?
I can't imagine a scenario where you want to be double tapping a foot switch to access a different scene, in the middle of a song etc?

Foot Switch for VFD?



This is for Chinese VFD: For the footswitch on a VFD drive you wire the footswitch into the normal FORWARD/REVERSE terminals on the VFD. The the terminals are normally wired & programmed for an OPEN contact to be STOP, and CLOSED contact to be RUN FORWARD or RUN REVERSE. You could put the footswitch in the "GND" wire so the footswitch would be series with the FORWARD/REVERSE terminals. That would allow you to put the selector switch in either FORWARD or REVERSE position and control the RUN function with the footswitch.

I "THINK" KBAC drives can be wired for Automatic Restart per section 7.6, page 17 of manual (A) &#; Rev. J00 &#; 7/26/) so two switches are not required. I "THINK" wiring for Auto Restart would allow a NO switch to be wired in place of the COM-RUN jumper to allow RUN-STOP operation. You'll need to do some testing with the drive to confirm how this will work. Read section 7.6 closely. The Chinese drives are MUCH simpler {g}.

I've thought about doing this, but haven't really felt the need since I'm using running the disk in fairly slow speeds, 600 RPM to 800 RPM, and sometimes a good bit less. VERY seldom (if ever?) do I run the full rpm motor speed.

I did just place an order for this switch (

Again, allow me to emphasize I have NO experience with the KBAC drives and could well be mis-understanding the wiring of the KBAC drives, so take what I wrote above with a grain of salt and double check everything. If the above is totally wrong be SURE to correct my post. I'm more interested in having the right info, than I am in being right myself.

I use Chinese drives due to low cost and simple programming and wiring. With filters over the air inlets of the NEMA 1 enclosures make the drives last a long time.Again, allow me to emphasize I have NO experience with the KBAC drives and could well be mis-understanding the wiring of the KBAC drives, so take what I wrote above with a grain of salt and double check everything.
