  • Page 5: Connecting The Motor

    5. Connecting the Motor motors should be run at only 70% of their rated current to prevent over heating. The DMD4022 can drive any 2-pahse and 4-pahse 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.

    Theoretically, this will reduce motor heating to 36% (due to P=I *R) of the original value. If 6400 the application needs a different standstill current, please contact Soprolec. Current Settings 8. Wiring Notes For a given motor, higher driver current will make the motor to output more torque, but at the In order to improve anti-interference performance of the driver, it is recommended to use twisted pair shield cable.

    Low level width not less than 7.5µs. 11. Protection Functions To improve reliability, the driver incorporates some built-in protection functions. The DMD4022 uses one RED LED to indicate what protection has been activated. The periodic time of RED is 3 Figure 9: Typical connection s (seconds), and how many times the RED turns on indicates what protection has been activated.

    turn on twice within each periodic time (3 s). Phase Error Protection Motor power lines wrong & not connected will activate this protection. RED LED will turn on four times within each periodic time (3 s). When above protections are active, the motor shaft will be free or the LED will turn Attention: red.
