Page 5: Introduction, Features And Applications
1. Introduction, Features and Applications Introduction The DMA860H is a fully digital stepper drive developed with advanced DSP control algorithm based on the latest motion control technology. It has achieved a unique level of system smoothness, providing optimal torque and nulls mid-range instability. -
Page 6: Operating Environment And Other Specifications
DMA860H Fully Digital Stepper Drive Manual V1.0 Pulse Voltage Isolation resistance MΩ Operating Environment and other Specifications Cooling Natural Cooling or Forced cooling Avoid dust, oil fog and corrosive gases Environment 0℃ － 50℃ Ambient Temperature 40%RH － 90%RH Operating Environment Humidity 70℃... -
Page 7: Pin Assignment And Description
Selecting Active Pulse Edge or Active Level and Control Signal Mode There are two jumpers J1 and J2 inside the DMA860H specifically for selecting active pulse edge and control signal mode, as shown in figure 2. Default setting is PUL/DIR mode and upward-rising edge active. -
Page 8: Connector P2 Configurations
The DMA860H can accept differential and single-ended inputs (including open-collector and PNP output). The DMA860H has 3 optically isolated logic inputs which are located on connector P1 to accept line driver control signals. These inputs are isolated to minimize or eliminate electrical noises coupled onto the drive control signals. Recommend use line driver control signals to increase noise immunity of the driver in interference environments. -

DMA860H Fully Digital Stepper Drive Manual V1.0 Figure 5: 4-lead Motor Connections Connections to 6-lead Motors Like 8 lead stepping motors, 6 lead motors have two configurations available for high speed or high torque operation. The higher speed configuration, or half coil, is so described because it uses one half of the motor’s inductor windings. -

6. Power Supply Selection The DMA860H can match medium and small size stepping motors (from NEMA frame size 17 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 11: Multiple Drivers
Selecting Supply Voltage The power MOSFETS inside the DMA860H can actually operate within +24 ~ +80VDC, including power input fluctuation and back EMF voltage generated by motor coils during motor shaft deceleration. Higher supply voltage can increase motor torque at higher speeds, thus helpful for avoiding losing steps. -
Page 12: Current Settings
DMA860H Fully Digital Stepper Drive Manual V1.0 Current Settings For a given motor, higher driver current will make the motor to output more torque, but at the same time causes more heating in the motor and driver. Therefore, output current is generally set to be such that the motor will not overheat for long time operation. -
