The PCL601USB is a single-axis step motor controller containing 2 Kbytes of nonvolatile stored programming space and quadrature encoder feedback. The user can write the program and then have the PCL601USB autostart the program on power up. It provides flexible, independent control of stepper motors from computers, or any machine controller with a USB port. It is also capable of standalone operation, making it an embedded machine controller. The easy to use Windows software, SMC60WIN, can be used to directly control motion and to program the PCL601USB. The PCL601USB also has the ability for real time functions. "Direct Mode" is used to directly control motion for Real Time Movements through serial communication. The PCL601 Series can be purchased with a step motor driver (see Driver Packs). Accessories such as a TWS7 (7 decade thumbwheel switch), 485SD9TB (RS232-RS485 data converter) and AA9MFC-6 (serial port cable), are purchased seperately. See Accessories on this website for details.
