This Item includes: 1 PC DQ542MA digital serial with 4.2A peak current, 50V, 128 Microstep,Matching Nema11, Nema16, Nema17 and Nema 23 stepper motors 1. DQ542MA Introduction: DQ542MA is a type of two-phase hybrid stepping motor driver, the drive voltage of it 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. Holding torque when DQ542MA runs under high speed, is also significantly higher than the other two-phase driver, what’s 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, and computer embroider machine, packing machines and so on. Features: l High performance, low price l Average current control, 2-phase sinusoidal output current drive l Supply voltage from 18VDC to 50VDC l Opto-isolated signal I/O l Overvoltage, under voltage, overcurrent, phase short circuit protection l 15 channels subdivision and automatic idle-current reduction l 8 channels output phase current setting l Offline command input terminal l Motor torque is related to speed, but not related to step/revolution l High start speed l High holding torque under high speed Electrical specification: Input voltage 18-50VDC Input current < 4A Output current 1.0A~4.2A Consumption Consumption:80W; Internal Insurance:6A Temperature Working Temperature -10~45°C; Stocking temperature -40°C~70°C Humidity No condensation, no water droplets gas Prohibition of combustible gases and conductive dust weight 300GS 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 pin ENBL+ 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 level is active, all control negative signals will be connected together to GND. When low electrical level is active, all control positive signals will be connected together to public port. Now give two examples( Open collector &PNP), please check them: 1/8W R must connect in the control signal part . 3.Function choice ( Using DIP pins to achieve this function) 1) Micro step resolution is set by SW 5,6,7,8 of the DIP switch as shown in the following table: SW5 OFF ON OFF ON OFF ON OFF ON OFF ON OFF ON OFF ON OFF SW6 ON OFF OFF ON ON OFF OFF ON ON OFF OFF ON ON OFF OFF SW7 ON ON ON OFF OFF OFF OFF ON ON ON ON OFF OFF OFF OFF SW8 ON ON ON ON ON ON ON OFF OFF OFF OFF OFF OFF OFF OFF PULSE/REV 400 800 1600 3200 6400 12800 25600 1000 2000 4000 5000 8000 10000 20000 25000 2) Standstill current setting SW4 is used for this purpose. OFF meaning that the standstill current is set to be half of the selected dynamic current and ON meaning that standstill is set to be the same as the selected dynamic current. 3) Output current setting: The first three bits (SW 1, 2, 3)of the DIP switch are used to set the dynamic current. Select a setting Closest to your motor’s required current Output current (A) SW1 SW2 SW3 PEAK RMS ON ON ON 1.00 0.71 OFF ON ON 1.46 1.04 ON OFF ON 1.91 1.36 OFF OFF ON 2.37 1.69 ON ON OFF 2.84 2.03 OFF ON OFF 3.31 2.36 ON OFF OFF 3.76 2.69 OFF OFF OFF 4.20 3.00 4) Semi-flow function: Semi-flow function is that there is not step pulse after 500 ms, the driver output current automatically reduced to 70% of rated output current, which is used to prevent motor heat. 4. Pins of motor & power: Motor and power pins 1 A+ Motors wiring 2 A- 3 B+ 4 B- 5,6 DC+ DC- Power supply Power supply :DC18-50VDC 5. Mechanical Specification: To have 20mm of space around, cannot be placed next to other heating devices. Whats more, avoid dust, oil mist, corrosive gas, heavy humidity and high vibration.
