Re: [CAD_CAM_EDM_DRO] pulse generator

Hi,
A 555 timer chip, a few resistors and capacitors and a potetntiometer are
all that is needed. I guess less than $2-3 in parts. Have a look here:

For 0-60rpm you're looking at 0-200Hz if the drive is a full-step drive. If
it's 1/2-step then 0-400Hz, 1/8-step 0-1600Hz and so on.

Hello,
I am setting up a stepper motor to drive a mechanism at variable
speeds, 0-60 rpm Spec sheets for the motor and driver can be found on
Anaheim Automation web site, the motor model is 34Y214S-LW8 and the driver
model is MBC10641. The tech support person at Anaheim Automation advised me
that I would need to purchase an external "pulse generator" in order to make
the setup work as I would like. I need to be able to change the speed of the
stepper motor on-the-fly without having it connected to a computer by simply
turning a knob such as on a potentiometer.
He told me I would be able to pick up a pulse generator from Radio Shack,
however I was at the store and they were not too helpful.
Any assistance would be appreciated.

Sincerely,
Denis
