HPSMD is a four channel system for actuating bipolar motors with max current of 2A/phase. The system allows simple and intuitive positioning. The movement to the target position follows a pre-programmed sequence of angular frequencies (acceleration, deceleration, fine steps). The system can operate in connection with absolute rotary SSI encoders. The movement can be blocked by 2 independent (end-limit) switches. Optionally, remote control over TCP/IP is available (web server).
