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
Key Features
Servopacks
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
Servomotors
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
