New FHA Integrated Drive from Harmonic Drive

November 12, 2021

DCS HarmonicDrive FHA 1 400

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. This evolutionary product eliminates the need for an external drive and greatly improves writing while retaining high-positional accuracy and torsional stiffness in a compact housing. This new mini actuator product is ideal for use in robotics.

Since it communicates via CANopen, only 4 conductors 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. Typical multi-turn encoders monitoring the motor input shaft require a battery to store the current position when power is lost to the system; however, the dual absolute encoders overcome this need. In other words, No Battery Required. When power is restored, the actuator knows its position.

Key Features:

Actuator + Integrated Servo Drive utilizing CANopen communication
24VDC Nominal +7 to 28VDC Supply Voltage Range
Single Cable with only 4 conductors 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 for initial tuning, commissioning, and analysis

Put to the Ultimate Test – Part 1: Torsion Tests by HELUKABEL

DCS Put to the Ultimate Test Part 1 Torsion Tests by HELUKABEL 1 400x275

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.

For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
