CNC Controller Stepper Motor Driver DM420 1.7A 12-36VDC for Nema17

Description: This item includes:1 pc Nema17 Stepper motor driver DM420 128micsteps 2.83A 12-36VDC Driver DM420Detail:(for Nema14/16/17 motor) DM420 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 run smoothly almost without noise and vibration. Hording torque when DM420A run 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: High performance, low priceAverage current control, 2-phase sinusoidal output current drive Supply voltage from 12VDC to 36VDC Opto-isolated signal I/OOvervoltage, under voltage, overcorrect, phase short circuit protection8 channels subdivision and automatic idle-current reduction 8 channels output phase current setting Offline command input terminal Motor torque is related with speed, but not related with step/revolutionHigh start speedHigh hording torque under high speedElectrical specification:Input voltage12-36VDCInput current＜ 2AOutput current0.44A- 2.83AConsumptionConsumption：40W；TemperatureWorking Temperature -10～45℃；Stocking temperature -40℃～70℃HumidityNot condensation, no water dropletsgasProhibition of combustible gases and conductive dustweight70G Pins assignments and description:1) Connector Pins Configurations Pin Function DetailsPUL +,PUL-Pulse signal, PUL+ is the positive end of pulses input pinPUL- is the negative end of pulse input pinDIR+,DIR-DIR signal: DIR+ is the positive end of direction input pinDIR- 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 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: Note: When VCC=5V, R=0When VCC=12V, R=1K, ＞1/8WWhen VCC=24V, R=2K,＞1/8WR 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: SW5ONOFFONOFFONOFFONOFFSW6ONONOFFOFFONONOFFOFFSW7ONONONONOFFOFFOFFOFFPulse/rev2004008001600320064001280025600Micro12481632641282) Standstill current settingSW4 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.
