The PCL602USB is a dual-axis step motor controller containing 2 Kbytes of nonvolatile stored programming space and quadrature encoder feedback. This device provides flexible and independent control of stepper motors from computers or any machine controller with a USB port. More specifically, the PCL602USB presents an easy way to implement motion systems requiring two axes and the precision that can be achieved on each axis through the use of encoder feedback. Accessories such as a TWS7 (7 decade thumbwheel switch) and AA9MFC-6 (serial port cable), are purchased separately. See Accessories on this website for details.
