Over-voltage and over-current protections 1.2 Applications The DMA860E stepper drive are designed to power 2 phase (1.8°) or 4-phase (0.9°) NEMA 23, 24, 34, and 42 hybrid stepper motors. It can be easily adopted in many industries (CNC, medical, automation, packaging…), such as X-Y tables, engraving machines, labeling machines, mills, plasma, laser cutters, pick and place devices, and so on. -

Connectors, DIP switches, and LED locations The DMA860E has three connector blocks P1&P2&P3 (see above picture). P1 is for control signals connections, and P2 is for output signals connections, P3 is for power and motor connections. The following tables are brief descriptions of the three connectors. -

3.4 P4 - Tuning Connector DMA860E has a tuning port with RS232 to modify the drive parameters, it is just used to modify parameter, not for equipment control because neither precision nor stability is sufficient. If you need a field bus drive, use a Leadshine RS485 or EtherCAT type drives: (http://www.leadshine.com/ProductSubType.aspx?type=products&category=stepper-products&producttype=stepper-dr... -

Fault Output When over voltage or over current protection happens, DMA860E red status LED light will blink and the impedance state between ALM+ and ALM- will change (from low to high or high to low depending on configuration) and can thus be detected. -

DMA860E Digital Stepper Drive User Manual 5. Motor Connection The DMA860E can drive 2-phase and 4-pahse bipolar hybrid stepper motors with 4, 6, or 8 wires. 5.1 Connections of 4-lead Motor The 4 lead motors are the least flexible and easy to connect. And the Speed – torque of motor depends on winding inductance. -

(frame size from NEMA 23 to 42) made by Leadshine or other motor manufacturers. To get 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). -
