Ultimate safety and security
Systems can be operated safely because the Σ-7 Servo Drives comply with safety standards and safety is ensured by monitoring.
Satisfies requirements of the SIL 3 of the IEC 61508 functional safety standards∗ (first in Japan) ∗: Certification scheduled for April 2014
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 |
- The safety function works even for a single problem.
- The safety function is enhanced with compliance with the EN ISO 13849-1 PLe (performance level e).
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.
Protect systems from high temperatures
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.
