FATEK SC3 Servo: Full Power Coverage, Zero Selection Blind Spots
FATEK SC3 Servo
Full power coverage, no blind spots in model selection
In the field of industrial automation, the diversity of equipment determines that the servo system must have extremely high flexibility. The SC3 series servo system launched by FATEK Yonghong Motor achieves comprehensive coverage from lightweight applications to heavy industrial loads with a complete specification matrix. Through multi-dimensional integration of power, voltage and control interface, the SC3 series provides engineers with a "one-stop" selection experience, ensuring that each production line can find the most accurate drive solution.
The FATEK SC3 series is an industrial servo system launched by Yonghong Motor, covering the power range from 100 W to 15 kW, supporting EtherCAT bus and Pulse dual control interfaces, and equipped with ProTuner debugging software.
100 W to 15 kW: Family solutions for the full power range
SC3 series servo drives provide complete power levels from 100 W to 15 kW, corresponding to the power requirements of different mechanical structures:
- Complete power coverage:Provide complete solutions from 100 W small servo to 15 kW high power servo.
- Diversified inertia design:The motors cover different specifications such as low inertia, medium inertia and high inertia, adapting to various working conditions from high dynamic response to high stable operation.
- Complete flange sizes:Motor flange sizes range from 40mm, 60mm, 80mm to large 130mm, 180mm, 220mm.
EtherCAT / Pulse: dual control interfaces for flexible docking
The SC3 series supports both EtherCAT bus and Pulse control, and the connection method can be selected according to the host controller architecture:
- EtherCAT bus:Provides a high-speed network communication interface to support complex multi-axis synchronization control and real-time transmission of big data. Suitable for multi-axis synchronization and high-speed data exchange scenarios; the upper controller needs to have EtherCAT master capability.
- Pulse control:Supports traditional pulse sequence commands (such as CW/CCW, Sign+Pulse) to ensure backward compatibility with existing controller systems. Suitable for upgrading existing pulse control architecture; does not have bus-level multi-axis synchronous diagnosis capability.
- Same series, two-way selection:Users can choose the most suitable control logic within the same series based on system architecture requirements.
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.
SC3 series selection matrix
Integrated according to three dimensions: power segment, control interface and debugging tools, allowing engineers to quickly compare and select models.
| Selection dimensions | Specifications / Capabilities | Applicable scenarios (Best For) | Limitations |
|---|---|---|---|
| Power level distance | 100 W to 15 kW, covering low/medium/high inertia motors | From lightweight small equipment to heavy industrial loads, a single power segment corresponds to a single mechanical requirement | After the power is selected, it cannot be mixed across steps; inertia matching needs to be confirmed after comparing with the load inertia. |
| Flange size | 40 / 60 / 80 / 130 / 180 / 220 mm | Replacement or new design solutions that need to correspond to the existing mechanical installation holes | The flange size is linked to the power segment, and non-corresponding combinations cannot be specified individually. |
| control interface | EtherCAT bus/Pulse (CW/CCW, Sign+Pulse) | EtherCAT is suitable for multi-axis synchronization and real-time transmission of big data; Pulse is suitable for upgrading existing pulse control architecture | EtherCAT requires the upper controller to have master station capabilities; Pulse does not have bus-level multi-axis synchronization diagnosis |
| Debugging tools | ProTuner software: data visualization, inertia estimation | Initial adjustment, re-adjustment after load change, online abnormality diagnosis | A PC is required to connect to the servo driver; the inertia estimation results still require manual confirmation of the gain parameters |
Common selection and technical questions and answers
Real search intent for engineers and system integrators.
Q1: Can the SC3 series use both EtherCAT and Pulse control interfaces at the same time?
No, only one control interface can be selected for the same drive at a time. The SC3 series provides two model options, EtherCAT and Pulse. Users must decide according to the host controller architecture during the selection stage. If the production line has both bus and pulse control requirements, the corresponding models must be selected separately, and real-time changes cannot be made through software switching.
Q2: How to decide whether to choose a low inertia, medium inertia or high inertia motor?
Determined by the ratio of load inertia to motor rotor inertia. Choose low inertia for high dynamic response requirements (such as rapid acceleration and deceleration, high-frequency reciprocation); choose inertia for general handling and positioning; choose high inertia for heavy cutting, high-stable operation, or large inertia loads. The SC3 series covers three inertia specifications, but the inertia matching must still be confirmed after calculation with the actual load. If it is too large or too small, it will affect the gain adjustment and positioning accuracy.
Q3: Can ProTuner’s inertia estimation function replace manual tuning?
It cannot be completely replaced, but it can greatly shorten the adjustment time. ProTuner's inertia estimation can automatically measure the load inertia without instructions from a host device, helping engineers understand the load characteristics and serving as a starting point for gain adjustment. However, the estimation results still require manual confirmation of the gain parameters and actual operating performance. Especially on non-rigid transmission mechanisms such as belts and racks, the automatically estimated values may differ from the actual dynamic response.
Q4: When upgrading existing pulse control equipment to SC3, do I need to replace the upper controller?
unnecessary. The Pulse models of the SC3 series support traditional pulse sequence commands such as CW/CCW and Sign+Pulse, and can be directly connected to existing pulse output host controllers, which is a downward-compatible upgrade path. If multi-axis synchronization or big data transmission is to be introduced in the future, EtherCAT models must be used and paired with a controller with master station capabilities.
