D-Series step motor driver modules  used with a PC or PLC which provides some motion control function

Operates with simple 'step' and 'direction' input signals, but also includes controls for output power and microstep size



DC-Series step motor driver/controller modules used as standalone motion controllers, or in a set commanded by a PC or PLC

Operates via the AM Communications Bus (high-speed high-reliability RS-485 serial), up to 32 controllers per bus segment  features a variety of form-factors and output power (phase current) level, with programmable current level, microstep size, velocity/acceleration, input outputs, and fixed-function controls (Stop, Go, Limits, Jog, Home, etc.)
