This item includes: 1 pc Stepper motor driver DM542A, peak 4.2A,18-50VDC, 128 MICSTEPS Detailed information DM542A is a type of two-phase hybrid stepping motor driver, The drive voltage of which is from 18VDC to 50VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with 42mm to 86mm outside diameter and less than 4.0A phase current. This circuit that it adopts is smiliar to the circuit of servo control which enables the motor run smoothly almost without noise and vibration. Hording torque when DM542A run under high speed is also significantly higher than the other two-phase driver, whats more, the positioning accuracy is also higher. It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, computer embroider machine, packing machines and so on.Features:l High performance, low pricel Average current control, 2-phase sinusoidal output current drivel Supply voltage from 18VDC to 50VDCl Opto-isolated signal I/Ol Overvoltage, under voltage, overcorrect, phase short circuit protectionl 15 channels subdivision and automatic idle-current reductionl 8 channels output phase current settingl Offline command input terminall Motor torque is related with speed, but not related with step/revolutionl High start speedl High hording torque under high speedElectrical specification:Input voltage18-50VDCInput current< 4AOutput current1.0A~4.2AConsumptionConsumption:80W; Internal Insurance:6ATemperatureWorking Temperature -10~45?;Stocking temperature -40?~70?HumidityNot condensation, no water dropletsgasProhibition of combustible gases and conductive dustweight200G Pins assignments and description: 1) Connector Pins Configurations Pin Function Details PUL +,PUL-Pulse signal, PUL+ is the positive end of pulses input pin PUL- is the negative end of pulse input pin DIR+,DIR-DIR signal: DIR+ is the positive end of direction input pin DIR- is the negative end of direction input pinENBL+ Enable signal: ENBL+ is the positive end of direction input pin. This signal is used for enabling/disabling the driver. High level for enabling the driver and low level for disabling the driver.ENBL-ENBL- is the negative end of direction input pin. Usually left unconnected (enabled) 2) Pins wiring diagram:PC’s control signals can be active in high and low electrical level. When the high electrical levelis active, all control negative signals will be connected together to GND. When low electricallevel is active, all control positive signals will be connected together to public port. Now givetwo examples( Open collector &PNP), please check them: Fig 1.
