It is recommended to mount the driver vertically to maximize heat sink area. Use forced cooling and so on. Its unique features make the DM856 an ideal solution for applications that require both method to cool the system if necessary.
Pin Function Details output). The DM856 has 3 optically isolated logic inputs which are located on connector P1 to accept Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each rising or falling edge active (software configurable); 4-5V when line driver control signals.
70% of their rated current to prevent over heating. 5. Connecting the Motor The DM856 can drive any 2-phase and 4-phase hybrid stepping motors. Connections to 4-lead Motors 4 lead motors are the least flexible but easiest to wire. Speed and torque will depend on winding Figure 6: 6-lead motor full coil (higher torque) connections inductance.
6. Power Supply Selection The DM856 can match medium and small size stepping motors (from NEMA frame size 17 to 34) 7. Selecting Microstep Resolution and Driver Output Current made by Leadshine or other motor manufactures around the world. To achieve good driving Microstep resolutions and output current are programmable, the former can be set from full-step to performances, it is important to select supply voltage and output current properly.
*R) of the original value. If Current Settings the application needs a different standstill current, please contact Leadshine. For a given motor, higher driver current will make the motor to output more torque, but at the same 8. Wiring Notes time causes more heating in the motor and driver.
Low level width not less than 2.5µs. 11. Protection Functions To improve reliability, the driver incorporates some built-in protection functions. The DM856 uses one RED LED to indicate what protection has been activated. The periodic time of RED is 3 s (seconds), and how many times the RED turns on indicates what protection has been activated.
