Providing up to 8A of continuous current, Performance Motion Devices', ION Microstepping Digital Drive targets semiconductor as well as medical, scientific, automation, industrial and robotic applications. In addition to high performance motion control, the unit provides network connectivity and amplification in a fully-enclosed module for dc brush, brushless dc, or step motors. The drive supports two-phase bipolar motors and can automatically switch between user-defined current modes. Communications are handled by either asynchronous serial (RS485) or CANbus network. The unit handles 8A continuous and 15A peak current, but an optional heatsink increases the current capability. To complement the selectable profiling modes that include S-curve, trapezoidal, velocity contouring and electronic gearing, the unit operates at 40 kHz PWM frequency with 102 µsec servo loop rate and has an advanced PID filter with velocity and acceleration feedforward.

These free camps are designed for children ages 10 to 18. Attendees are introduced to 3D CAD software and shown how 3D printers can make their work a reality. Many classes were nearly 50 percent girls and 50 percent boys.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
