The 34MD Series is a compact construction that implements a microstepping driver and a step motor in one streamline package. With the two parts combined into one casing, the need to include motor wires has been eliminated. The 34MD Series has an output current capability of 1.5 Amps minimum to 10.0 Amps maximum （Peak Rating）.The microstepping driver will operate off 20VDC minimum to 80VDC maximum. The inputs are optically isolated with a minimum sourcing of 1.0 mA per input （+3.5VDC minimum to +8.6VDC maximum）. The clock input is set to receive either positive or negative edge clocks with a maximum frequency of 100KHz. The microstepping driver features a resolution of 2000 steps/revolution, providing smooth rotary operation. The 34MD series comes in motor stack lengths of 1, 2, or 3 allowing for varying amounts of start-up torque and inertia. The 34MD series features include built in over current and short circuit shut down, automatic 50% reduction in current after clock pulses stop being received, and status LEDs to indicate power on （green LED） and clocks being received （yellow LED）.
