5 70g weight

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 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 overvoltage, under voltage, overcurrect, 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
Input voltage 12-36VDC
Input current < 2A
Output current 0.44A- 2.83A
Consumption Consumption:40W; 
Temperature Working Temperature -10~45&deg;C; Stocking temperature -40&deg;C~70&deg;C
Humidity Not condensation, no water droplets
gas Prohibition of combustible gases and conductive dust
weight 70G
 
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 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
