Harmonic Drive LLC Product
Harmonic Drive LLC offers a complete range of digital drives for use with Brushless (AC) actuators. The drives can communicate via CANopen, DeviceNet, EtherCat, and MACRO. As well they can simply be operated with indexer, step/direction, PWM or + or 10V commands, or ACSII and discrete I/O.
REL combines EtherCAT networking with 100% digital control of brushless or brush motors in an AC-line powered package that can operate from single or three-phase mains with continuous power output to 4 kW.
Command Interface
- CANopen over EtherCAT (CoE)
- ASCII and discrete I/O
- Stepper commands
- ±10V position/velocity/torque command
- PWM velocity/torque command
- Master encoder (Gearing/Camming)
