The EDE1204 is capable of self-clocking in the free-standing 'RUN' mode, as well as external clocking in the 'STEP' mode. In addition, half-stepping and directional control are also available. The TTL-level outputs sequence dual H-Bridges (one per coil) such as the L293 Dual H-Bridge IC or dual H-Bridges made from discrete transistors (see schematics section).

Key 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 compatible. 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 command causes counterclockwise rotation of motor, reverse the sequence of the motor’s four phase wires. ) Half-Ste.
