Little Step-U Motor Controller
Using an intelligent module allows the host system to concentrate on the task at hand while the Little Step-U performs all calculations and operation of the motor. The desired operating speed, ramp time and drive mode can be configured once and then a single command used as required, to move to fixed or relative positions. While the motor is in motion, a BUSY output is active and the movement can be optionally interrupted by one of the two external inputs.
