Harmonic Drive Robot Joint Module-FAQ



What is the encoder resolution of your joint modules?

Our harmonic drive modules feature a high-precision 16-bit encoder resolution, providing 65,536 discrete positions per revolution. This means the full 360° rotation is divided into extremely fine increments for exceptional positional accuracy at the motor end.



Do your harmonic joint modules include STO (Safe Torque Off) functionality?

HONPINE harmonic drive modules utilize a different safety approach. Instead of STO, we incorporate a reliable built-in electromagnetic brake system that automatically engages to stop rotation immediately when power is disconnected, ensuring safe operation.



Can the harmonic drive modules provide torque measurement?

While HONPINE standard robot joint modules don't include integrated torque measurement, we can accommodate torque sensing requirements by integrating an external torque sensor. Please contact our technical team for customized solutions.



Are general-purpose I/O interfaces available on the harmonic drivemodules?

Due to the highly compact design of our integrated driver system, HONPINE current robot joint modules don't include general-purpose I/O pins. This streamlined design allows for optimal space savings in robotic applications.
