Motor control for iC7 series drives
With the iC7 series, you can control highly dynamic applications using a standard drive, thanks to innovative control and added sensors for more precision.
Superior low-speed performance • Control for maximum efficiency • Highly dynamic performance • Fast commissioning using Automatic Motor Adaptation (AMA) at standstill • Highest possible machine accuracy • More integrated sensors for better performance.
STO SIL3, Performance Level e (PL e) is available as standard • Extend functionality with plug-and-play ease • Manage system-level safety using STO Feedback signal for enhanced diagnostics • Program functional safety parameters in the MyDrive® Insight tool • Functional safety via fieldbus.
Active Front-end control Option, AFE technology enables you to build systems with low harmonic and regenerative operation. Choose between two variants to suit the application: • Low harmonic: The AFE controls the input current to extremely low THD, suited to virtually harmonic-free application demands • Regenerative: In addition to the low harmonic functionality the drive can also feed braking energy back to the grid.
Grid monitoring functionality Voltage measurement on the grid side enable the drive to monitor the supply voltage, the harmonic distortion and frequency to aid in diagnosis of power quality issues.
Motor control impact on dynamic performance Intelligence can be used to maximize performance. With numerous integrated sensors, iC7 series drives provide motor control offerings to meet a wide range of application requirements: • FVC+ Flux vector control • FVC+ with encoder ensures best performance and requires measurement of motor shaft position • FVC+ encoder less delivers highly dynamic performance and advanced auxiliary functions • VVC+: Voltage vector control is a robust concept suitable for fans and pumps • Simple U/f control: basic concept used mostly in special applications with the need to manually set the motor U/f characteristic.
Secure-by-design IC7 is equipped with market leading hardware-based protection against unauthorized access with a built-in crypto chip on the control unit. Use a microSD card to copy settings, log data, download software and activate additional features – all protected by the crypto chip ensuring end-to-end encrypted data transfer.
