Page 3: Introduction, Features And Applications
The driven motors can run with much smaller noise, lower heating, smoother movement than most of the drives in the markets. Its unique features make the DM442 an ideal solution for applications that require low-speed smoothness. -
Page 4: Specifications
(unit: mm [inch]) The DM442 has two connectors, connector P1 for control signals connections, and connector P2 for power and motor connections. The following tables are brief descriptions of the two connectors. More detailed descriptions of the pins and related issues are presented in section 4, 5, 9. -

4 lead motors are the least flexible but easiest to wire. Speed and torque will depend on winding output). The DM442 has 3 optically isolated logic inputs which are located on connector P1 to accept inductance. In setting the drive output current, multiply the specified phase current by 1.4 to determine the peak output current. -

6. Power Supply Selection The DM442 can match medium and small size stepping motors (from NEMA frame size 14 to 34) made by Leadshine or other motor manufactures around the world. To achieve good driving Figure 6: 6-lead motor full coil (higher torque) connections performances, it is important to select supply voltage and output current properly. -

Pulling or plugging Dynamic current setting connector P2 with power on will cause extremely high back-EMF voltage surge, which may damage the drive. -
Page 9: Protection Functions
11. Protection Functions Phase error protection To improve reliability, the drive incorporates some built-in protection functions. The DM442 uses 12. Frequently Asked Questions one RED LED to indicate what protection has been activated. The periodic time of RED is 5 s (seconds), and how many times the RED turns on indicates what protection has been activated. -
