EDE1204
features the ability to change the stepping rate while the motor is stepping and to selfclock an unlimited number of steps in continuous 'RUN' mode. Inputs are TTL/ CMOS patible.
RUN mode
In the 'RUN' mode, activated by a low on pin 10, the EDE1204 will cause the motor to rotate according to the following parameters: Direction (pin 7): 1 = clockwise, 0 = counter-clockwise (If a clockwise mand causes counterclockwise rotation of motor, reverse the sequence of the motor’s four phase wires.) Half-Stepping (pin 8): 1 = normal stepping, 0 = half stepping (doubles step resolution) Speed Control [C,B,A] (pins 13,12,11): these three active-low bits select one of eight rotational speeds. Refer to Tables One & Two below for speed range details.
Note: Throughout this datasheet, "1" refers to +5V, and "0" refers to 0V (Ground).
