DM860I Full Digital Stepper Drive Manual 3. Pin Assignment and Description The DM860I 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.
DM860I Full Digital Stepper Drive Manual 4. Control Signal Connector (P1) Interface The DM860I can accept differential and single-ended inputs (including open-collector and PNP output). The DM860I has 3 optically isolated logic inputs which are located on connector P1 to accept line drive control signals. These inputs are isolated to minimize or eliminate electrical noises coupled onto the drive control signals.
DM860I Full Digital Stepper Drive Manual Figure 6: 6-lead motor half coil (higher speed) connections Full Coil Configurations The full coil configuration on a six lead motor should be used in applications where higher torque at lower speeds 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 over heating.
DM860I Full Digital Stepper Drive Manual 6. Power Supply Selection The DM860I can match medium and small size stepping motors (frame size from NEMA24 to 34) made by STEPPERONLINE or other motor manufactures around the world. To achieve good driving performances, it is important to select supply voltage and output current properly.

DM860I Full Digital Stepper Drive Manual Standstill Current Setting SW4 is used for this purpose. OFF meaning that the standstill current is set to be half of the selected dynamic current, and ON meaning that standstill current is set to be the same as the selected dynamic current. The current automatically reduced to 50% of the selected dynamic current one second after the last pulse. If the application needs a different standstill current, please contact STEPPERONLINE.
DM860I Full Digital Stepper Drive Manual following diagram: Figure 11: Sequence chart of control signals Remark : a)t1: ENA must be ahead of DIR by at least 5s. Usually, ENA+ and ENA- are NC (not connected). See “Connector P1 Configurations” for more information. b)t2: DIR must be ahead of PUL effective edge by 5s to ensure correct direction; c)t3: Pulse width not less than 2.5s; d)t4: Low level width not less than 2.5s. 11.
DM860I Full Digital Stepper Drive Manual 12. 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. It is important to document each step in the troubleshooting process.
