Ultimate system performance
The high-performance of Σ-7 SERVOPACKs translates into ultra-high-speed and ultra-high-accuracy control, which maximizes system performance.

Σ-7S Single-axis SERVOPACKs
3.1 kHz response frequency Optimized for specific applications: New models in EX and FT series to be released Improved vibration suppression |
Ripple compensation
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.
Enhanced vibration suppression function
- Notch filter Suppresses high-frequency vibrations of 500 Hz or higher. ⇒Number of filters increased from 2 to 5.
- Anti-resonance control adjustment Suppresses vibrations at frequencies ranging from several hundred Hz to 1 kHz. ⇒Vibrations can now be suppressed at two different frequencies (in comparison with one frequency in earlier models).
- Vibration suppression Suppresses vibrations at low frequencies (30 Hz and lower).⇒Vibrations can now be suppressed at two different frequencies (in comparison with one frequency in earlier models).
These functions can be adjusted automatically using the autotuning function.

Σ-7W 2-axis SERVOPACKs
2-axis SERVOPACKs (200 W × 2 axes to 1 kW × 2 axes) 3.1 kHz response frequency Improved vibration suppression |

Σ-7 Servomotors
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) |
High-resolution, 24-bit encoder
Σ-7 Servomotors (50 W or greater) use encoders with a resolution that are 16 times higher than those used in Σ-V Servomotors.
High efficiency and low heat generation
Σ-7 Servomotors use an optimized magnetic circuit that improves motor efficiency and reduces heat generation. (comparison with typical models.)
