Overview
The ZeroErr eRob110 T-Type Robot Joint is an integrated robot joint for rapid robot assembly. It is offered in CANopen and EtherCAT versions, with or without a torque sensor, reduction-ratio selections of 50, 80, or 100, and optional multi-loop memory. Its integrated design is stated to save the manpower and time costs associated with selecting, designing, purchasing, and assembling hundreds of mechanical and electronic components.
Features
- 18 mm hollow shaft for routing cables, air lines, and similar services; the routing design is stated to have no bending-life impact.
- Corner mounting holes support direct mounting without a casing; this design is stated to reduce joint weight and improve the robot payload-to-weight ratio.
- Fully differential interface with strong anti-interference performance and dual anti-loosening connectors that can be connected in series or parallel.
- Friction damping brake.
- IP65 rating.
Configuration-Specific Feature Information
Feature material with unspecified configuration scope identifies eight core components: a motor-side absolute encoder, DC driver temperature sensor, output-side multi-turn absolute encoder, friction brake holder, frameless torque motor, torque sensor, and precision harmonic reducer. It also identifies a built-in dual absolute encoder with full closed-loop control, single-turn and multi-turn power-off position memory, wear-free accuracy, and real-time compensation for reducer transmission errors and backlash.
The same material states repeatability up to ±7 arcseconds and absolute accuracy up to ±15 arcseconds*. It describes a high-reliability friction brake with no wobble on stop, no shaking on start, full-load zero-speed start capability, no wear powder during operation, no noise during rotation, and 100% full-speed heavy-load emergency-stop capability.
Driver Communication and Control — Configuration-Specific
The driver feature illustration lists EtherCAT, CANopen and Modbus communication, access to position-loop, speed-loop and current-loop data, and real-time PID adjustment for robot applications with variable loads and inertia.
Listed driver interfaces include ±10 V analog interface, pulse/direction, I/O, RS485, an external encoder interface and STO. Availability depends on the driver configuration; the selectable communication versions for this listing are EtherCAT and CANopen.
The driver illustration labels a D × L space of 70 × 67 mm. This illustration dimension is not the overall dimension of the eRob110 T joint; use the 116 × 147.5 × 18 mm outer diameter × length × through-hole specification below for this product.
