The newest member of the SMC-series offers now a Closed-Loop with a specially designed new absolute encoder system. Just power-on the system, no homing necessary, you know where you are.
By the way, the new SMC-hydra supports classical rotary and linear encoders 1 Vpp, 2 Phase stepper motors, 2 Phase and 3-Phase direct drives, and standard DC-brush motors. In preparation is a piezo-motor implementation for our PiCo stages. The very powerful processor architecture (Power-PC) gives us a high flexibility offering new features. Modern communication-interface via Ethernet 10/100 Mbit and High-Speed RS-232 simplifies the software integration. The VENUS-3 command-interpreter is based on our well known Venus-1 and Venus-2 interpreters.
