Drives for printed circuit board (PCB) USD series

The USD modules are bipolar stepper motor drives designed for PCB mounting.

They provide the perfect solution for saving space, removing cables, and perfectly integrate with the electronics control in mono or multi-axis applications.

There are 12 different models split in three current sizes and four different functionalities. Some models are controllable by the STEP and DIRECTION signals and others via serial link. Models are available in versions with a step resolution of half step and in a version with microstep resolution up to 25600 step/rev.

Through the proprietary communication protocol, LEP11, it is possible to control up to 32 different drives using a simple serial line.

The available commands allow configuring the acceleration time, the minimum and maximum frequency, and perform absolute or relative positioning. It is also possible to read in real time the operating status of each connected module.

Three lines configurable as input and output complete the available I/O in the serial version of the modules. These lines, suitably configured, can also trigger the start of the drive.
