The PMD-51031 is a low cost, yet sophisticated stepper motor driver. It is a high efficiency 3 Amp chopper driver with an automatic power reduction circuit that minimizes the power dissipation while idling. The driver has 400PPR(1/2) and 4000PPR(1/20) operation modes with sine waveform output signal, providing an accurate degree resolution. The PMD-51031 has clock & direction inputs (CK&DIR), to be controlled by a host computer, a CNC, a remote controller or a PLC. It has GO & DIR inputs for manual operation and two “End of Travel” switch inputs, to prevent any out of limit move (caused by either hardware fault or software mistake). The driver is aimed at low to medium power systems, and it can drive 4, 6, and 8 leads stepper motors, of 0.2 to 6 Amp phase current. All driver’s inputs are 5 to 24 volts range, for lab and industrial use, and its power requirement is a single 12 to 48 volts DC source of any kind, regulated or unregulated, with an output current of 3 Amp. The driver incorporates a special noise filter circuit that eliminates noise on the driver lines.
