driver board: NPAD10BF
A bipolar chopping drive, the NPAD10BF has an output current up to 1.2A/phase (peak), which allows the device to drive most two-phase stepper motors. With an input voltage range from 12-30 Vdc, the NPAD10BF board can drive tin-can, linear, and hybrid stepper motors. With the excitation mode, the board has full, ½, ¼, and 1/16 microsteps.
The NPAD10BF driver, which has four input signals (Pulse, Dir, Enable and Reset), includes an on board switching voltage regulator, an automatic current reduction function, and a reset for sequence and disenable.
