Σ-7 products set a new industry standard in servo capability redefining the possibilities in motion automation. – Σ-7 is engineered to bring new responsiveness, reliability and effectiveness to the automation that powers your productivity
One amplifier for Linear, Rotary and Direct Drive motors
Features with IEC 61508, SIL 3 Safe Torque Off
Advanced safety functions SS1, SS2, SLS
Speed frequency response: 3.1 kHz
Network compatibility models with MECHATROLINK-II, III & IV, EtherCAT and analog/pulse Train interfaces
Alarm diagnostic function: Presumes possible causes of the alarm and immediately displays suggested corrective actions
Improved Tuning-less Mode delivers reliable stability with inertia ratios up to 30:1 Advanced Autotuning automatically adjusts nearly 20 gain and filter parameters to cancel vibration, rippling, friction and resonance.
Vibration suppression, anti- resonance compensation, friction model compensation and ripple compensation improves machine speed, accuracy and smoothness.
Regerative Power Sharing is available for dual-axis SERVOPACKs or DC-Bus connections with single-axis SERVOPACKs
24-bit absolute encoder feedback (16,777,216 pulses/rev) for 16x better resolution than the industry-leading Sigma-5
Maximum torque: 350% (small capacity)
20% Reduction in motor size and motor heating, for better efficiency and easier implementation
At higher temperature environments (40oC ambient), at higher altitudes (>2,000 meters) or in harsh motor environments (IP67 rated)
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
SigmaWin+ Software tool for effortless parameterization and advanced monitor functions
