Product Detail
1. High performance, low price 2 voltage 12V-36VDC. 3 For neam08 to nema 17 motor 4 less than 2.0A current 5 70g weight stepper motor driver: Introduce: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 DM420A rund at high speed is also significantly higher than the 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 pricel  Average current control, 2-phase sinusoidal output current drivel  Supply voltage from 12VDC to 36VDCl  Opto-isolated signal I/Ol  Overvoltage, under voltage, overcurrect, phase short circuit protectionl  8 channels subdivision and automatic idle-current reductionl  8 channels output phase current settingl  Offline command input terminall  Motor torque is related to speed, but not related to step/revolutionl  High start speedl  High holding torque at high speed  Electrical specification:

       2) 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. Select a setting Closest to your motor’s required current

 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.   Pins of motor & power:
