The FT609 is a stepper logic controller. It will completely control a stepper motor through one 2400 baud line. The FT609 does not need any external components except a driver circuit for the stepper motor coils. The FT609 does not have the high current capacity to directly drive the stepper motor, therefore a driver circuit such as a L293 (Push-Pull four channel driver), UND2540 (Quad Darlington Power Driver) or a transistor circuit is needed.

FT609 Features: Only one serial input line to control all aspects of the FT609. Variable stepping speeds from .417 milliseconds to 27.3 seconds. Directional control. Has a single Stepping Mode. Has count function that will step the motor the exact number of steps needed. Has a home pin function that will automatically stop on home pin or step a certain number of steps before stopping. Two modes, automatically shut off stepper motor current when not stepping and constant stepper motor current. Automatic ramp up and ramp down functions. This allow for the gradual increase/decrease in stepping times to accommodate large loads or high speeds. Three different stepping sequences Wavedrive, Twophase, and Halfstep.
