Product Description:

The PMM-BD-53130-10 is a pulse-train driver module produced by Sanyo Denki in the PM Drivers series. It supports open-loop positioning of stepper motors used in packaging lines and semiconductor handlers by translating direction and clock inputs into phase currents that advance the rotor in discrete increments. By matching logic-level signals to the power stage, the module forms a compact interface between a PLC or motion card and the motors it controls.

For timing integrity, the CK/U-D input recognizes pulses as short as 10 μs, provided the duty cycle does not exceed 50%; this allows high-speed command edges to reach the power stage without violating setup times. Internally, the optically isolated interface has an input resistance of 330 Ω, keeping source currents moderate for typical 5 V or 24 V controllers. The driver accepts a bus voltage of 24 VDC or 36 VDC and excites both phases with an operating current of 0.75 A per phase, allowing either a 60 mm or 86 mm motor frame to be energized without external heat sinks. With a suitable signal width, the counter reaches 400 kilopulses per second; combined with an internal resolution count of 16, this rate supports finely graduated microstep operation.

Direction inputs require a minimum pulse width of 50 μs, so controllers must space consecutive clockwise or counterclockwise commands accordingly. Step interpolation is selected through switches that provide division settings ranging from 250 to 1, offering a choice between smoother movement and lower computational demand. Origin detection occurs once every ten steps in full-step mode and once every twenty steps in half-step mode, simplifying homing routines. For diagnostics, an open-collector monitor output can sink a maximum current of 5 mA and withstand a collector-emitter voltage of 30 V, making fault or status signals available to external indicators or PLC inputs.
