Product Overview DM542 DSP control of the digital two-phase hybrid stepper motor driver, suitable for the phase current in 4.2 Abelow, 0D 39, 42, 57, 60, 86 mm four, six, eight-wire two-phase hybrid stepper motor. Can be set in 128 various subdivisions and 4.2A various currents, internal increase motor dedicated control algorithm, can be used ford ifferent motor corresponding operating parameters, so that the motor running very smooth, vibration an dnoise is min imal. Built-in overheat, overcurrent, overvoltage detection to protect the stable operation of the drive Application Field Suitable for various automation equipment and instruments in the field of motion control, such as: 3D printers, laser processing equipment, engraving equipment, medical equipment, measuring equipment, electronic processing equipment, textile and clothing equipment, etc. It is used in equipment where users expect low vibration and low noise, and is the first choice in areas with strong cost-effective competition. Interface Definition Control signal interface Name Function PUL PUL- Pulse input signal The pulse effective edge is adjustable, and the default pulse rising edge is effective; in order to reliably respond to the pulse signal, the pulse width should be greater than 1.2us. 5-24VDC level compatible. DIR DIR- Direction input signal High/low level signal, to ensure reliable commutation of the motor, the direction signal should be established at least 5us before the pulse signal. The initial running direction of the motor is related to the motor winding connection. Interchanging any phase winding (such as A and A- exchange) can change the initial running direction of the motor. 5-24VDC level compatible. ENA ENA- Enable control signal This input signal is used to enable or disable the driver output. When ENA is connected to a low level (or the internal optocoupler is turned on), the driver will cut off the current of each phase of the motor to make the motor in a free state and not respond to step pulses. When this function is not needed, the enable signal end can be left floating. 5-24VDC level compatible.
