Harmonic Drive and Harmonic Planetary are registered trademarks of Harmonic Drive LLC.


Harmonic Drive LLC offers a complete range of digital drives for use with Brushless (AC) and Brush (DC) actuators. Drives for both AC and DC power are available. Harmonic Drive Motion (HDM) software installed on a PC is used to set-up the drives with Harmonic Drive actuator parameters. The drives can communicate via CANopen, DeviceNet, EtherCat, and MACRO. And, they can simply be operated with indexer, step/direction, PWM or + or 10V commands, or ACSII and discrete I/O.
In addition to being compatible with Harmonic Drive encoder protocols, the drives can be made available for use with many other motor manufacturer encoder formats.
