AutomationDirect's SureStep line of motion control products now includes a low cost of entry digital stepper drive in a compact package. The standard stepper drive operates with high-speed pulse input signals (Step and Direction, or jumper-selectable CW/CCW step) and has a selectable resolution range of 200 to 20,000 steps per revolution. Additional features include a switch-selectable automatic self test, digital filters to prevent position error from electrical noise on command signals, and optically isolated I/O. The unit's switch-selectable microstep emulation feature provides smoother, more reliable motion in full and half-step modes. Operated with a 24 to 65 VDC power supply, this microstepping drive has a running output current of 0.5 to 7.5 Amps.
