FATEK SC3 Servo: Intelligent Tuning, One-Key Stable Operation
FATEK SC3 Servo
Intelligent adjustment, one-click stable running
In a smart manufacturing environment, servo system debugging is often the most time-consuming step for developers. The SC3 series servo drives launched by FATEK realize the transformation from "manual debugging" to "intelligent adaptive" through deep integration of automatic calibration technology. SC3 focuses on solving parameter threshold and mechanical vibration problems to ensure that the equipment can demonstrate excellent stability under various working conditions.
The FATEK SC3 series is an industrial servo driver launched by Yonghong Motor. It has built-in Tuning-less function, Auto-Tuning algorithm and multi-dimensional vibration suppression mechanism, and is equipped with ProTuner debugging software.
Applicable boundaries: Auto-Tuning must be executed under conditions where the load can operate; up to 5 sets of built-in notch filters can be built in, corresponding to high-frequency mechanical resonance; terminal vibration suppression is targeted at low-frequency oscillations; friction and backlash compensation must be effective under the premise that the commutation error can be measured. ProTuner requires a PC connection to operate.
Adjustment-free and automatic gain: stable control that even novices can use
The SC3 series greatly simplifies the complexity of servo drives through two mechanisms: adjustment-free and Auto-Tuning:
- Tuning-less:Users do not need to be proficient in servo debugging principles to achieve fast and stable operation. Even if the load changes during operation, the system can continue to maintain stability. It is suitable for scenarios where the manpower for machine adjustment is limited and the load change amplitude is less than medium. If the load inertia changes drastically, it is still recommended to use manual gain fine-tuning.
- Auto-Tuning algorithm:Instantly and automatically identify the load inertia and automatically adjust the gain parameters. This technology not only automatically sets the notch frequency, but also significantly shortens the equipment debugging cycle. It is suitable for initial adjustment and re-adjustment after load change; it must be performed under the condition that the motor can run and cannot be completed statically at shutdown.
Multi-dimensional vibration suppression: eliminate mechanical resonance and end jitter
For various physical vibrations generated by mechanical structures, SC3 provides a three-layer suppression solution:
- 3.1 kHz speed response bandwidth:The extremely high response speed makes command following more immediate and reduces deviations from the source. It is suitable for high dynamic acceleration and deceleration and high-frequency reciprocating motion; the bandwidth advantage requires a mechanical structure with sufficient rigidity to be fully realized.
- Built-in 5 notch filters:Specifically designed for high-frequency vibration, it accurately suppresses mechanical resonance by automatically setting the notch frequency. It is suitable for transmission mechanisms such as belts and racks that are prone to high-frequency resonance; the upper limit of the number of filters is 5 sets, and resonance beyond the range needs to be improved by the mechanical end.
- Terminal vibration suppression function:Specially strengthens the control of low-frequency vibration, which can effectively suppress the vibration of the mechanical end and improve the stability after positioning. Suitable for cantilever, long-stroke gantry and other end-end structures that are prone to shaking; the suppression effect is related to mechanical rigidity and load inertia ratio.
Friction and backlash compensation: pursuit of precision at the micro level
In order to achieve a silky smooth motion trajectory, SC3 adds two compensation technologies to the dynamic control:
- Automatic compensation mechanism:Integrate friction compensation and backlash compensation functions to effectively reduce deviations during commutation. It is suitable for frequent reversal and low-speed contour processing scenarios; the compensation amount needs to be set on the premise that the reversal error can be measured.
- Improve processing accuracy:Through compensation technology, the stability during low-speed operation is significantly improved to meet the needs of high-precision processing and positioning tasks. It is suitable for precision milling, electric discharge machining and measurement positioning; when the backlash is too large, it still needs to be adjusted by the mechanical end first.
Professional debugging tool: ProTuner
All adjustment functions can be operated intuitively through the ProTuner software, without the need for an on-site panel to be executed independently:
- Data visualization:The system monitoring function can instantly display servo status, I/O status and alarm records. Suitable for online diagnosis and troubleshooting; a PC is required to connect to the servo drive.
- Inertia estimation:Rotational inertia estimation can be easily performed without the need for instructions from a host device, helping engineers accurately grasp load characteristics. It is suitable for initial machine adjustment and re-tuning after load changes; the estimated results still require manual confirmation of the gain parameters.

Common tuning and technical questions and answers
Real search intent for engineers and system integrators.
Q1: After turning on the Tuning-less function, do I still need to manually set the gain?
In most cases this is not required. The adjustment-free function will automatically maintain system stability and continue to operate even if the load changes during operation. However, when the load inertia changes drastically or the mechanical rigidity is extremely low, it is recommended to turn off the adjustment-free function and use Auto-Tuning or manual fine-tuning of the gain to obtain a more accurate dynamic response.
Q2: Can 3.1 kHz speed response bandwidth and 5 notch filters solve all mechanical resonances?
It cannot solve all resonances, but it can cover most common high-frequency vibrations. The 3.1 kHz bandwidth allows for more real-time command tracking and reduces deviations from the source; 5 notch filters can automatically set the notch frequency to suppress specific resonance points. If there are more than 5 sets of resonant peaks in the mechanical structure, or the resonant frequency is lower than the effective range of the filter, it must still be improved by the mechanical end (such as strengthening the rigidity, replacing the coupling).
Q3: Will friction and backlash compensation interfere with Auto-Tuning?
It will not interfere directly, but it is recommended to enable them in sequence. Auto-Tuning is responsible for identifying load inertia and gain parameters, while friction and backlash compensation deal with commutation deviation and low-speed stability. The two functions have different levels. In practice, it is recommended to complete the Auto-Tuning and vibration suppression settings first, then enable the compensation function and verify it with a low-speed contour test to avoid the compensation amount covering up the problem of unoptimized gain.
Q4: Can the inertia estimation results of ProTuner be directly applied to mass production machines?
It can be used as a starting point, but it is not recommended to be applied directly to mass production. The inertia estimation is based on the load characteristics of the machine on a single machine. There are assembly tolerances and transmission parts differences between mass-produced machines. It is recommended to use the estimated value of the first machine as the benchmark, and then conduct sampling verification and fine-tuning on the same batch of machines to ensure that the dynamic response of the entire batch is consistent.
