Product Description:

The PMM-MD-23210-10 pulse-motor driver is manufactured by Sanyo Denki within the PM Drivers series. Designed for industrial automation, the unit sits between a motion controller that provides step and direction pulses and a permanent-magnet or hybrid motor that requires phased current. By translating incoming logic pulses into regulated phase currents, the driver allows conveyors, indexing tables, and small actuators to move with repeatable step angles under low-voltage DC power. This arrangement supports controlled acceleration and deceleration while keeping the motor synchronized with pulse commands from the host controller.

The electrical section uses a unipolar output stage, so each motor winding is energized from a single supply rail, simplifying coil insulation and limiting switching losses. Control inputs reach the device through an optocoupler, providing optical isolation from external controllers and reducing ground loops. The driver accepts a main supply of 24/36 V DC ±10%, and it can source up to 2 A while delivering a rated phase current of 1 A per phase. The maximum input rate is 20,000 pulses per second, and the pulse duty cycle is limited to 50%. This frequency establishes the fastest attainable step rate without pulse distortion or missed command transitions.

Input impedance is set by a 330 Ω resistor, so typical 5 V logic outputs can drive the optocoupler input without excessive current draw. The insulation system maintains at least 10 MΩ of resistance between the power path and the chassis, and the circuit withstands 500 V AC during dielectric testing. Monitoring is supported by an open-collector output that sinks a maximum of 5 mA and can be pulled up to 30 V DC, enabling fault or positional feedback to the host PLC. Mounting holes measuring 4 mm in diameter accommodate M3 screws, allowing the assembly to be secured to compact panels or DIN mounting plates. The assembly weighs 0.18 kg, which limits mechanical stress when it is attached to lightweight enclosures.
