Digital microstepping drive prevents motor position errors

The SureStep line by AutomationDirect now includes a digital stepper drive that is designed to prevent position error from electrical noise on command signals.

January 3, 2013

AutomationDirect’s SureStep line of motion control products now includes a digital stepper drive. 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 V dc power supply, this microstepping drive has a running output current of 0.5 to 7.5 Amps. 

The SureStep regeneration clamp has a built-in 50W braking resistor and features a mounted-on heat sink, 24-80 V dc voltage range, and 6-pin screw terminal block. LED indicators show when power supply voltage is present and when the clamp is operating. External power is connected internally to an “Input Diode” which protects the power supply from high regeneration voltages and the system from connecting the power supply in reverse.
