In sensorless control, the iC7 series ensures superior motor control performance at low speed without the use of encoders, thanks to original new control algorithms.
The iC7 series delivers very fast response due to market-leading shaft performance. Many applications which used an encoder in the past can now run on sensorless control. It is also important to state that encoders will still be required in some applications, mostly because of safety concerns.
Enjoy improved performance with more built-in sensors and boosted processing power. The motor reacts consistently to commands maximizing machine performance and product quality.
Automatic Motor Adaption (AMA) at standstill reduces drive commissioning complexity and time in demanding applications, for both encoder-based and encoder-free sensorless control. No advanced tuning procedures or manual tuning for consistent performance are required, and you can identify key motor parameters with no need to decouple the motor load.
For easy commissioning, the automated commissioning sequence measures electric parameters of the motor and optimizes it:
You can tailor the control performance to your specific application by choosing the most relevant integrated application software. Each application offers dedicated control features related to specific demands of specific industries.
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.
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:
Motor control ensures the motor always runs at maximum possible torque for the given current - ensuring highest possible motor efficiency. Maximum Torque Per Ampere (MTPA).
Using iC7 drives, you will always achieve the best possible efficiency, no matter which motor you use.
Drives in iC7 series use the AMA function to determine the motor parameters and tune the motor control to maximize efficiency.
For induction motors, the Automatic Energy Optimization (AEO) function reduces magnetization flux in the motor, according to the working point. AEO is often used in pumps and fans where the motor runs continuously under the part load conditions, as well as in fixed-speed applications such as escalators.
For synchronous motors, iC7 drives use a maximum torque per ampere (MTPA) control approach to ensure maximum motor efficiency. Iron losses in synchronous motors are significantly lower than in induction motors. For synchronous motors such as permanent magnet motors (PM motor) the strategy to optimize efficiency therefore involves reducing copper losses.
