DNA Dan's discussion about secret drive
DaOld Man:
Ok, jumping a little ahead of the tutorial, here is a simple method using a selector switch with the small "Secret Drive".
You could use the limit switches that are on arcade buttons for the limits.
I dont see why this wouldnt work. Looks like it's OK to leave the enable input always high, from the info in the data sheet, but since I dont have one of these drives, you will have to do the testing.
With enabled input high, when the direction input goes low (or 0 volts), looks like the drive automatically dynamically brakes, stopping the motor faster.
DNA Dan:
You should change your name to "ImDaMAN"!
Exactly what I need. I am going to order some parts today and I'll be starting construction this weekend.
Thanks a bunch! I'll be sure to document the build as I go and post if I need more help.
DNA Dan:
I forgot to ask about the voltage regulator. If I choose to use something like this:

Where does this fit in the circuit diagram? Does it just go in after the secret motor driver but before the motor on VDC?
Also on the switches, for this to work the switch needs to be continuously held down to break the circuit correct?

Im not sure you can use that with the secret drive, but if you could, it would most likely go between the secret drive and the motor. Theres not much information with it, but it says it can go as low as 5 vdc. Isnt your motor 5 vdc? So Im really not sure if you can use this or not.
You could use this instead of the secret drive, since it is a drive in itself.
You would have to go back to the DPDT switch setup I first suggested, im pretty sure.
See if that company will share the hook up instructions before you order it, might save you some effort and money.
Ask them how the DPDT switch wires in to reverse direction.
As for the switches, yes they need to be held down continuously when the monitor is in that switches' position.
If the monitor drifts off the switch, the drive and motor will come back on, unless you have the SPDT switch in the OFF position.
There is yet another way to do this that could use monetary switches. Momentary means that the switch is pushed then then immediately released.
But this method would use two small relays and two push buttons for H and V, instead of the toggle switch.
Wanna see another drawing?
