Overview: This driver board is designed to drive the stepper motor of the MDL-003 Motorized Delay Line. It can also drive any two phase stepper motor whose drive requirements fall within the board’s voltage and current limits. Note that all references to the home and far-end sensors apply only if the board is being used with an MDL-003.

High (5V): enabled Low (0V): disabled b. Clock pulse (pin 3): Square wave TTL levels 0/5V. Pulse: , minimum width 2µs recommended: 50% duty cycle The clock rate controls the MDL scan speed. Depending on the step mode, the motor moves ¼, ½, or 1 full step per clock pulse received. c. Directional signal (pin 1): TTL levels.

Manual Control Add-on Board An optional manual control add-on board is available. This board allows the user to control the MDL-003 or other stepper motor without the use of an external control circuit. It provides controls for setting the scanning rate and for performing either continuous scanning or manual forward or reverse motion control.
