∑-7 Series 24189 views
Created with the design concept of "seven ultimate e-motional solutions," the Σ-7 series delivers the world's highest performance while providing other features such as further improvements in safety and an environmentally friendly design to meet the changing needs of its users. This series offers solutions that are guaranteed to satisfy users in all kinds of scenarios in the life-cycle of systems.
The high-performance of Σ-7 SERVOPACKs translates into ultra-high-speed and ultra-high-accuracy control, which maximizes system performance.

3.1 kHz response frequency Optimized for specific applications: New models in EX and FT series to be released Improved vibration suppression |
Σ-7 SERVOPACKs can reduce speed ripples caused by motor cogging, even for machines for which speed loop gains cannot be set high. This ensures smooth operation.
These functions can be adjusted automatically using the autotuning function.

2-axis SERVOPACKs (200 W × 2 axes to 1 kW × 2 axes) 3.1 kHz response frequency Improved vibration suppression |
 |
Compact dimensions (approx. 80% smaller than our earlier models.) High-resolution 24-bit encoder incorporated (16,777,216 pulses/rev) Maximum torque: 350% (small capacity) |
Σ-7 Servomotors (50 W or greater) use encoders with a resolution that are 16 times higher than those used in Σ-V Servomotors.
Σ-7 Servomotors use an optimized magnetic circuit that improves motor efficiency and reduces heat generation.
(comparison with typical models.)
Yaskawa's original tuning-less function has undergone further development.
Stable operations can be achieved without having to adjust gains.
With Yaskawa's original tuning-less function, systems can run without vibration for a load with 30 times (max.) of load moment of inertia. Systems remain stable even with load changes during operation.
| Σ-V Series | Σ-7 Series | |
|---|---|---|
| Allowable load moment of inertia ratio | 30 times (max.) | 30 times (max.) |
| Max. control gain | Speed loop gain 40 Hz (approx.) |
Speed loop gain 70 Hz (approx.) |
When the allowable load moment of inertia ratio is 30 times:
The Σ-7 Servo Drives can be used in harsh environments and conserve energy.
Optimal systems can be easily set up in different countries and under a variety of conditions.
?SGM7A (IP22 for 7.0 kW), SGM7J and SGM7G models?
Protective Structure (IEC 144, 529, DIN40050, JEM1030)
Systems can be operated safely because the Σ-7 Servo Drives comply with safety standards and safety is ensured by monitoring.
Certification will make it easier to set up systems that conform to safety standards for press machines and other systems in Europe and other regions. Certification also helps reduce the number of hours required for wiring and of peripheral devices.
Complies with Stop Category 0 (Safe Torque Off)
| Safety standards | Performance level & category | |
|---|---|---|
| Safety of machinery | EN ISO13849-1 | PLe (CAT3) |
| IEC 60204-1 | Stop Category 0 | |
| Functional safety | IEC 61508 | SIL 3 |
| IEC 62061 | SIL CL3 | |
| IEC 61800-5-2 | STO |
| Note : | Although the safety performance level of the Σ-V series Servo Drives is PLd (performance level d), the benefits described in the figure on the left apply. |
Σ-7 SERVOPACKs and Servomotors are equipped with temperature sensors that can directly monitor temperatures of machines and detect abnormalities to prevent failures. Real-time temperatures can be viewed on a display by using Machine Controllers.
Cloud-based storage of product data facilitates data retrieval when needed.
Customers can now place single or multiple orders for SERVOPACKs in the Σ-7 series after specifying parameters at the factory shipment stage. No longer is it necessary to write the parameters at the system assembly site, which means that production lead times can be reduced.
Features
Simply access the MechatroCloud service∗ and hold your smartphone over the QR code of the product. You can access the product data stored in the MechatroCloud, and view the manual for that product.
The service life of the maintenance can be estimated, and the users are notified when the parts should be replaced. System failure can be prevented because parts can be replaced before products break.
