The 17MD Series has a compact construction that implements a microstepping driver and a NEMA 17 stepper motor in one streamline package. With the two parts combined into one casing, the need to include motor wires has been eliminated. The high-torque stepper motor can generate up to 62 oz-in of torque. The microstepping driver will operate with voltage from 12VDC to 24VDC. The inputs are capable of running from either open collector or TTL level logic outputs. The microstepping driver features resolutions from 200 - 1600 steps/revolution, providing smooth rotary operation. The 17MD Series comes in a single shaft version with three different motor stack lengths allowing for varying amounts of start-up torque and inertia. The 17MD Series features built in over temperature and short circuit shut down. It also has automatic 70% reduction in current after clock pulses stop being received, and status LEDs to indicate power on (green LED) and clocks being received (yellow LED). A power supply is required (purchased separately).
