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;... -

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. -
Page 7: Regulated Or Unregulated Power Supply
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. -

The user can choose three drop-down menus by clicking “Option”, including Com Configuration, Read RAM: Read parameter settings from the drive’s RAM to the ProTuner. - Page 15 However, if the user does not want to tune the current loop after changing a different stepping motor, then Motor self-test and parameter auto-setup technology of the AM882 can replace manual tuning Ki: Integral Gain. Integral Gain helps the drive to overcome static current errors. A low or zero value the drive with ProTuner.

Page 17: Anti-Resonance Introduction
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. - Page 18 AM882 Digital Stepping Drive Manual V1.0 AM882 Digital Stepping Drive Manual V1.0 Please remember to click Write EEprom to write the final parameter settings to the drive when finish tuning.
