PWM/HPWM Stepper Motor Controller

[DavyJones]

These type of controllers require a digital direction input, an digital enable input, and last but not least, a digital step input. The controller will advance the motor 1 step for every digital input pulse. Depending on the steps per rev. setting made thru the dip switches.

Agreed..... I think I understood that what I am missing is if I am am going to send PWM/HPWM out on one of the pins (lets say as an example I set it up for 200 pules per revolution) is that 200 pulses per second or? How if I set it up for 200 pulses per revolution would you regulate the speed?
Thanks
