This Item includes: 1pcs Nema 17 stepper motor driver DM420A 2.83A 128micsteps 12-36VDC for Nema 8 , 11 , 17 stepper motors Note:We sell 100% original authentic products,quality reliable. DQ420MA DQ420MA is a type of two-phase hybrid stepping motor driver, the drive voltage of which is from 12VDC to 36VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with 20mm to 42mm outside diameter and less than 2.0A phase current. This circuit that it adopts is similar to the circuit of servo control which enables the motor to run smoothly almost without noise and vibration. Holding torque when DQ420MA driver runs at high speed is also significantly higher than other two-phase drivers, 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 12VDC to 36VDC l Opto-isolated signal I/O l Over-voltage, under voltage, over-current, phase short circuit protection l 8 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 at high speed Electrical specification: Input voltage 12-36VDC Input current 1/8W When VCC=24V, R=2K,>1/8W R must connect in the control signal part 3. Function choice (Using DIP pins to achieve this function) 1) Microstep resolution is set by SW 5,6,7,8 of the DIP switch as shown in the following table: SW5 ON OFF ON OFF ON OFF ON OFF SW6 ON ON OFF OFF ON ON OFF OFF SW7 ON ON ON ON OFF OFF OFF OFF Pulse/rev 200 400 800 1600 3200 6400 12800 25600 Micro 1 2 4 8 16 32 64 128 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 SW1 SW2 SW3 PEAK RMS ON ON ON 0.44 A 0.31 A OFF ON ON 0.62 A 0.44 A ON OFF ON 0.74 A 0.52 A OFF OFF ON 0.86 A 0.61 A ON ON OFF 1.46 A 1.03 A OFF ON OFF 1.69 A 1.20 A ON OFF OFF 2.14 A 1.51 A OFF OFF OFF 2.83 A 2.00 A 4) Semi-flow function: Semi-flow function is that there is not step pulse after200 ms, the driver output current automatically reduced to 40% of rated output current, which is used to prevent motor heat. 4. Pins of motor & power Motor and power pins 1 A+ Motor’s wiring 2 A- 3 B+ 4 B- 5,6 DC+ DC- Power supply Power supply :DC12-36VDC The peak input current cannot be up to 2A 5. Mechanical Specification: To have 20mm of space around, it cannot be placed near to other heating devices. What’s more, avoid dust, oil mist, corrosive gas, heavy humidity and high vibration. (Unit=mm) 6. Adjustment of troubleshooting 1) The status on light’s indication PWR: green, normal work light. ALM: red, failure light, the motor with phase short-circuit, overvoltage and under-voltage protection. 2) Troubles Alarm indicator Reasons Measures LED off turn Wrong connection for power Check wiring of power Low-voltages for power Enlarge voltage of power Motor doesn’t run, without holding torque Wrong connection of stepper motor Correct its wiring RESET signal is effective when offline Make RESET ineffective Motor doesn’t run, but maintains holding torque Without input pulse signal Adjust PMW & signal level Motor runs wrong direction Wrong wires’ connection Change connection for any of 2 wires Wrong input direction signal Change direction setting Motor’s holding torque is too small Too small relative to current setting Correct rated current setting Acceleration is too fast Reduce the acceleration Motor stalls Rule out mechanical failure Driver does not match with the motor Change a suitable driver About us ?
