  • Page 7: Full Coil Configurations

    DM542T Full Digital Stepper Drive Manual V2.0 Full Coil Configurations The full coil configuration on a six lead motor should be used in applications where higher torque at lower speed is desired. This configuration is also referred to as full copper. In full coil mode, the motors should be run at only 70% of their rated current to prevent overheating.

  • Page 8: Power Supply Selection

    V2.0 Power Supply Selection The DM542T can match medium and small size stepping motors (frame size from NEMA17 to 34) made by Leadshine or other motor manufactures around the world. To achieve good driving performances, it is important to select supply voltage and output current properly. Generally speaking, supply voltage determines the high speed performance of the motor, while output current determines the output torque of the driven motor (particularly at lower speed).

    DM542T Full Digital Stepper Drive Manual V2.0 11.Frequently Asked Questions In the event that your drive doesn’t operate properly, the first step is to identify whether the problem is electrical or mechanical in nature. The next step is to isolate the system component that is causing the problem. As part of this process you may have to disconnect the individual components that make up your system and verify that they operate independently.
