How to set the maximum current limit for the robot joint module
2025-08-07
During the operation of a robot joint module, properly setting the maximum current limit is crucial for ensuring stable operation and extending its service life. This article details how to set the maximum current limit for the joint module via the driver software.
Setting the maximum current limit requires SDO parameters 0x60E0 or 0x60E1. These parameters are expressed in thousandths of the maximum current. The default value is 750, which limits the current to 75% of the maximum current. For example, changing the parameter value to 912 means the current limit is 91.2% of the maximum current. By adjusting these two parameters, you can flexibly adjust the current limit ratio based on actual operating conditions.
In addition, the maximum current value can be read at SDO parameter 0x6075 in milliamperes. Knowing the specific maximum current value helps us more accurately calculate and set the current limit, ensuring optimal joint module performance within a safe range.
To do this, first confirm the driver software version, then access the SDO parameter setting interface to find the corresponding parameter and adjust it. After completing the setup, it's recommended to perform a test run to observe the joint module's operating status and ensure the current limit is set appropriately.
The above steps complete the maximum current limit setting for the robot's joint module, ensuring safe and stable operation.

HONPINE single- and dual-encoder robot joint modules are compatible with communication protocols such as CAN, CANopen, and EtherCATIn the field of robot joint modules, encoders are crucial components, and communication protocols are the "language" that enables encoders to work efficiently with other devices. Our joint modules support both single and dual encoders and are compatible with multiple communication protocols, including CAN, CANopen, and EtherCAT. Today, we will provide a detailed introduction to these protocols.- HONPINE Anti-Backlash Planetary Gearbox: Redefining CNC Machine Tool Boundaries with Ultra-High Bending StiffnessAmong gearbox performance metrics, bending stiffness (often overlooked compared to precision and torsional stiffness) directly determines the limits of CNC machine tool machining. HONPINE’s anti-backlash planetary gearbox is redefining these limits with its ultra-high parameters.
- Breaking Precision Barriers: How HONPINE's Anti-Backlash Planetary Reducer Outperforms Harmonic & RV ReducerThe ultra-high precision anti-backlash planetary reducer has an angle transmission accuracy of up to 7 arc seconds and a positioning accuracy of up to 5 arc seconds, which is much higher than the accuracy level of current harmonic reducers and RV reducers. Its torsional rigidity and main bearing overturning rigidity are much stronger than those of RV reducers, and the service life is longer than that of traditional harmonic reducers. Ultra-high precision anti-backlash planetary reducers give robots and machine tools better performance. They push the accuracy limit of ultra-high rigidity reducers to 15 arc seconds, filling the market gap and making ultra-high precision reducers available for high-end industrial machines.
Cup-Type Harmonic Drive Effectively Addresses Short Lifespan Issues of Harmonic DriversIn industrial robots, harmonic drives are widely used in joint transmission systems due to their high precision, high torque transmission, and smooth operation. These characteristics make harmonic drives an ideal choice for applications requiring precise control and high performance, such as industrial robots, aerospace equipment, and precision instruments. To solve the problem of fatigue failure and short lifespan of the flexspline—a critical component in harmonic drives—HONPINE has designed a cup-type harmonic drive.- Robot Joint Module Parameter Power-Off Saving Operation GuideIn the daily use of robot joint modules, the stable preservation of parameters is the key factor to ensure the continuous and efficient operation of the equipment. For robot joint modules, mastering the correct parameter power-off saving method can effectively avoid data loss caused by accidental power failure.
RV Reducer Gearbox: The Core Technology Behind Industrial Robot PrecisionThe RV reducer gearbox is developed on the basis of traditional cycloid planetary transmission. Its reduction structure consists of the first-stage planetary reducer and the second-stage cycloid pinwheel reducer. It uses at least two eccentric shafts to connect the secondary reduction mechanism. The housing and cycloid pinwheel are matched and driven by solid castings and steel components, which form a closed differential gear train. The RV reducer gearbox not only overcomes the shortcomings of general cycloid pinwheel transmission but also has a series of advantages such as high precision (backlash less than 1 arc minute), high rigidity, high durability, high output density (high torque and compact), wide reduction ratio range, and low vibration.
24V 48V Robot Joint Module:Choose the Write Voltage for Robots and AutomationWhen selecting a robot joint module, voltage matching is a key factor that directly affects the performance, safety, compatibility, and operational stability of the equipment. Electrical components such as robots, servo motors, and controllers are designed to operate within a specific voltage range. In sufficient voltage can lead to insufficient power, slow response, or even failure to start; excessive voltage may burn out the circuit or shorten its life. HONPINE's standard joint modules include two voltages: 24V and 48V. They each play a unique role to ensure the efficient operation of robots and automation equipment.- Brushless Motor is an Important Component of Robot Joint ModuleAs manufacturing technology rapidly advances toward digitalization and intelligence, the robotics industry continues to evolve, introducing innovations that enhance automation in various fields.
