Section 2. 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. For the MDL-003, the home sensor indicates the minimum delay
position, and the far end sensor indicates the maximum delay position. Forward
scanning means that the delay is increasing, and reverse scanning means that the delay
is decreasing.
Section 3. Device Description:
3.1 Dimensions
The board has 4 mounting holes, one in each corner of the board. The mounting hole
diameter is 1.5mm. The mechanical drawing below is primarily to provide mounting hole
location and dimensional information. It does not include the electrical connectors, which
may extend beyond the edges of the board.
Figure 1 Mechanical drawing (board only, excluding connectors). Dimensions in mm.
Note: Board orientation in this figure is the same as in Figure 2.
