  • Page 3: Introduction, Features And Applications

    The driven motors can run with much smaller noise, lower heating, smoother movement than most of the drives in the markets. Its unique features make the AM882 an ideal solution for applications that require low-speed smoothness.
  • Page 4: Applications

    It is recommended to use automatic idle-current mode, namely current automatically reduce to machines, and so on. Its unique features make the AM882 an ideal solution for applications that 60% when motor stops, so as to reduce drive heating and motor heating;...
  • Page 5: Selecting Active Pulse Edge And Control Signal Mode

    The AM882 can accept differential and single-ended inputs (including open-collector and PNP inductance. In setting the drive output current, multiply the specified phase current by 1.4 to output). The AM882 has 3 optically isolated logic inputs which are located on connector P1 to accept determine the peak output current.

    6. Power Supply Selection The AM882 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 Figure 6: 6-lead motor full coil (higher torque) connections performances, it is important to select supply voltage and output current properly.

    1600 Selecting Supply Voltage 3200 6400 The power MOSFETS inside the AM882 can actually operate within +20 ~ +80VDC, including 12800 power input fluctuation and back EMF voltage generated by motor coils during motor shaft 25600 deceleration. Higher supply voltage can increase motor torque at higher speeds, thus helpful for avoiding losing steps.

    Repeats: Motion repeat times. If it is bidirectional, one repeat is moving forward then back. AM882 drive provides robust anti-resonance control to stop the vibrations and maintain equilibrium. This feature requires that the drive be configured with respect to the total inertia in the system. If set Distance: Moving distance in one direction in revolution.
