The eRob Rotary Actuator User Manual provides users with detailed instructions and operational guidelines for ZeroErr’s joint modules. It is designed to help users safely and properly operate ZeroErr products and efficiently build robotic systems.
-
Enhancement of “Safety Guide”.
-
Addition of Section 6.6 — “Important Wiring Instructions”.
- Section 6.6 “Important Wiring Instructions" provides users with detailed explanations regarding wiring through eRob center holes, methods for fixing cables and batteries, and Module Housing Grounding. It offers precautions and operational guidance for potential issues related to cable arrangement and module housing grounding that may arise during critical wiring processes, thereby enhancing the safety and reliability of eRob usage.
-
Enhancement of section 7.1 “Instruction and Caution” about brake
- A new precaution has been added: "Do not apply a load torque exceeding the standard qualified values from the factory test (static braking torque test with power off and not enabled) listed in Table 7-1." This explicitly warns of the hazard that the joint module may fail to maintain position lock, leading to load slippage, thereby alerting users to avoid dangerous operations and mitigate risks of personal injury and joint damage.
-
Enhancement of section 18.1 “Seam Allowance Requirement of Flange Connection”
- The output shaft length requirement is to ensure:
(1) the radial positioning accuracy of the output flange;
(2) the load moment is transmitted through the output flange seam allowance to the precision cross roller bearing that directly supports the external load.
The roundness and flatness of the customer’s load flange seam allowance should be as close as possible to the required values specified in Table18-1. Excessive roundness or flatness will lead to uneven force on the output end of the eRob, which will lead to abnormal noise or vibration of the eRob. The seam allowance of the customer’s load flange must not be painted. Painting this surface may cause flatness deviation, resulting in uneven loading on the module out put end. Consequently, the encoder disk mounted on the module output shaft may shift, leading to a positional offset in the output encoder readings after power-off and restart.
