The stepper motor drive modules of the USDxxx series have been designed for circuit board assembling and are the optimal solution to reduce sizes and eliminate wiring.

Perfectly integrable with the electronics of the machine, they often allow to realize one only electronic board to contain all the electronic circuits necessary to the machine.

Totally twelve different models are available, split in three current sizes and four different functionalities. Some models are controllable through the STEP and DIRECTION signals, others through the serial link. For both of them are available versions with a step resolution of half step and versions which allow the microstep resolution up to 25.600 step/rev.

Through a protocol designed to minimize communication latency, it is possible to connect up to 32 different drivers using a simple two wires serial link. The commands set is wide and complete: it allows to set up the acceleration times, the minimum and maximum frequency, etc; it allows to execute absolute positioning or relative to the current position and, furthermore, it allows to read in real time the functioning state of the module and the instant position of the motor. The motor position is represented with a resolution of 32bit.
Three general purposes I/O lines freely settable as input or output, complete the serial version of the modules. Such lines, opportunely set, can also trigger a positioning start or emergy stop.
