Harmonic Drive LLC announces new mini actuator with Integrated Servo Drive

Harmonic Drive LLC

Harmonic Drive LLC, the leader in high precision motion control announces new FHA mini actuators with an integrated servo drive. This evolutionary product eliminates the need for an external drive and greatly improves wiring while retaining high-positional accuracy and torsional stiffness in a compact housing.

The FHA-C Mini Series is a family of extremely compact actuators that deliver high torque with exceptional accuracy and repeatability. As part of the FHA-C Mini family, an integrated servo drive version utilizing CANopen® communication is now available. Since it communicates via CANopen, only 4 wires are needed: CANH, CANL, +24VDC, 0VDC. A single-turn 14bit (16384 cpr) gear output sensing encoder has been integrated along with a single-turn 15bit (32768 cpr) motor input sensing encoder providing a true absolute encoder that does not require a battery within 360° of rotation of the output.

Our engineering team incorporated more features and capabilities without greatly impacting the size and mass of the actuator.

Key Features:

  • Actuator + Integrated Servo Drive utilizing CANopen communication
  • 24VDC Nominal +7-28VDC Supply Voltage Range
  • Single Cable with only 4 wires needed: CANH, CANL, +24VDC, 0VDC
  • Zero Backlash
  • Dual Absolute Encoders
  • Panel Mount Connectors with 4 exit options
  • Output Sensing Encoder 14bit (16384 cpr) resolution
  • Input Sensing Encoder 15bit (32768 cpr) resolution
  • Control Modes Including Torque, Velocity, and Position Control, CSP, CSV, CST
  • Harmonic Drive HDL Software

The FHA-C Mini series actuators with an integrated servo drive are among the latest products developed at HDLLC in Peabody, MA.
