RSF-5B IDT Supermini Actuator
SKU
rsf-5b-idt
Product Details
The RSF-5B IDT Supermini Actuator integrates a high-torque, zero backlash Harmonic Drive® gear and a servo drive into a compact form, optimizing for the term "Actuator + Integrated Servo Drive." Its advanced design supports CANopen® communication, simplifying installation by eliminating the need for external drives and reducing wiring complexity. This actuator maintains exceptional accuracy and torsional stiffness, making it perfect for robotics applications.
Communication is streamlined through CANopen, requiring only four conductors: CANH, CANL, +24VDC, and 0VDC. It incorporates a high-resolution, single-turn 14-bit (16,384 counts per revolution) gear output sensing encoder, enhancing its performance. For additional actuator options with integrated servo drives, consider the FHA-IDT series.
RSF-5B IDT Supermini Actuator Features:
- Actuator with Built-in Servo Drive and CANopen® Communication
- Operates on a 24VDC nominal supply voltage, with a 7VDC to 30VDC operational range
- Simplified cabling using a single cable with four conductors: CANH, CANL, +24VDC, 0VDC
- Innovative Zero Backlash Harmonic Drive® Gearing System
- Durable, replaceable flex-rated cable assembly with versatile front and rear exit options
- High-precision Input Sensing Encoder with 14-bit resolution (16,384 cpr)
- Versatile Control Modes including Torque, Velocity, Position, CSP, CSV, CST
- Supported by Harmonic Drive® HDL Software for enhanced functionality
Options:
Flex-rated extension cables with robust sealed connectors for extended reach and reliability
