Product Description
DM422 2 phase stepper motor driver
Product Description:
Overview
The DM422D is a new generation high-performance digital stepper driver based on DSP with advanced control algorithm. The motors driven by DM422D can run with much smaller noise and much less vibration than other drivers in the market. The DM422D possess the feature of lower noise, lower vibration, and lower heating. The DM422D's voltage is DC 20V-40V. It is suitable for all the 2 phases hybrid stepper motor whose current is less than 2.2A. The maximum step number of DM422D is 51200 steps/rev (microstep is 1/256 ). Its current range 0.5A-2.2A. DM422D has automatic semi-flow, over-voltage, under voltage and over-current protection function.
Applications
It can be applied in a variety of small scale automation equipment and instruments, such as labeling machine, cutting machine, packing machine, drawing machine, engraving machine, CNC machine and so on. It always performs well when it is used in equipment which requires for low-vibration, low-noise, high-precision and high-velocity.

Driver functions descriptions
Driver function | Operating instructions |
Output current setting | Users can set the driver output current by SW1-SW3 three switches. The setting of the specific output current, please refer to the instructions of the driver panel figure. |
Microstep setting | Users can set the driver Microstep by the SW5-SW6 switches. The setting of the specific Microstep subdivision, please refer to the instructions of the driver panel figure. |
Automatic half current function | Users can set the driver half flow function by SW4. "OFF" indicates the quiescent current is set to half of the dynamic current, that is to say, 0.5 seconds after the cessation of the pulse, current reduce to about half automatically. "ON" indicates the quiescent current and the dynamic current are the same. User can set SW4 to "OFF", in order to reduce motor and driver heating and improve reliability. |
Signal interfaces | PUL is the setting pulse input; DIR is the stepper motor direction input; OPTO is the power supply for signal port + 5V; ENA is the motor free input. |
Motor interfaces | A+ and A- are connected to a phase winding of motor; B+ and B- are connected to another phase winding of motor. If you need to backward, one of the phase windings can be reversed. |
Power interfaces | It uses DC power supply. Recommended operating voltage is 20VDC-40VDC, and power consumption should be greater than 100W. |
Indicator lights | There are two indicator lights. Power indicator is green. When the driver power on, the green light will always be lit. Fault indicator is red, when there is over-voltage or over-current fault, the red light will always be lit; after the driver fault is cleared, if re-power the red light will be off. |
Installation instructions | Driver dimensions:66×56×20mm, please refer to dimensions diagram. Please leave 10CM space for heat dissipation. During installation, it should be close to the metal cabinet for heat dissipation. |
Control signal and external interface:
Phenomenon | Reason | Solution |
The red indicator is on. | 1.A short circuit of motor wires. | Inspect or change wires |
2.The external voltage is over or lower than the driver's working voltage. | Adjust the voltage to a reasonable rang |
3.Unknown reason | Return the goods |
