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.
