DM805-AI Hardware Installation Manual 4. Operating Mode The DM805-AI supports four operating modes selected by the DIP switch SW7 and SW8, shown as the following table. Mode Description 0~5V Speed Analog 0-5V Speed Mode Lo/Hi Speed Low and High Speed Mode... -
Page 11: Signal Sequence
Signal Sequence After power-up, the DM805-AI does not response to the analog 0-5V input immediately. The Enable and Run signal should be activated prior to the analog 0-5V input. The drive is enabled when the Enable/Disable input is unconnected and the motor shaft has holding torque at that time. -
Page 12: Low/High Speed Mode
Signal Sequence After power-up, the DM805-AI does not make the motor run immediately. The Enable and Run signal should be activated firstly. Drive is enabled when the Enable/Disable input is unconnected. After Run signal is activated, the Speed can be applied to the drive for low/high speed selection. -

When the input ramp exceeds the value set by the potentiometer, the actual output ramp will be limited by the potentiometer value. -
Page 15: Pulse/Direction Mode
DIP switch SW5 and SW6. 5. Control Signal Requirement Pulse/Direction Mode DM805-AI can support Pulse/Direction and CW/CCW control signal modes. In order to avoid some fault operations and deviations, PUL, DIR and ENA should abide by some rules, shown as following diagram: Remark: ENA must be ahead of DIR by at least 5us. -
Page 16: Connecting The Motor
Low level width not less than 2.5us. 6. Connecting the Motor The DM805-AI can drive any 2-pahse and 4-pahse hybrid stepping motors. 4-lead Motors Connections 4 lead motors are the least flexible but easiest to wire. Speed and torque will depend on winding inductance. In setting the drive output current, multiply the specified phase current by 1.4 to determine the peak output current. -
Page 17: 8-Lead Motors Connections
DM805-AI Hardware Installation Manual 8-lead Motors Connections 8 lead motors offer a high degree of flexibility to the system designer in that they may be connected in series or parallel, thus satisfying a wide range of applications. Series Connections A series motor configuration would typically be used in applications where a higher torque at lower speeds is required. Because this configuration has the most inductance, the performance will start to degrade at higher speeds. -
Page 18: Power Supply Selection
7. Power Supply Selection The DM805-AI 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 performances, it is important to select supply voltage and output current properly. - Page 19 DM805-AI Hardware Installation Manual The recommended power supply voltage for DM805-AI is 24-72VDC: HWMN-DM-R2011060...

Page 24: Configure The Drive
10. Configure the Drive The DM805-AI uses an 8-bit DIP switch to set operating mode, microstep resolution and motor operating current as follows. The dynamic current setting by SW1, SW2 and SW3 is active for all operating mode. The microstep resolution setting by SW5 and SW6 only takes effect in Pulse/Direction mode. -

Page 26: Idle Current Setting
Idle current setting When there is no pulse applied to the DM805-AI and the time exceeds the idle-time which can be configured via the PC based software, the drive goes into idle status. SW4 is used to set the idle-current, OFF meaning that the motor coil current is automatic reduced, and ON meaning that current is the same as the selected dynamic current. -
Page 27: Protection Functions
11. Protection Functions To improve reliability, the drive incorporates some built-in protection functions. The DM805-AI uses one RED LED to indicate what protection has been activated. The periodic time of RED is 3 or 5 s (seconds), and how many times the RED turns on indicates what protection has been activated. -
Page 28: Frequently Asked Questions
DM805-AI Hardware Installation 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. -
