Speed [rpm] Torque [%] Motor control for iC7 series drives Need cutting-edge motor control? 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 encoderless low-speed performance In encoderless control, the iC7 series ensures superior motor control performance at low speed thanks to original new control algorithms. 400 300 200 100 0 -100 -200 -300 -400 0 110 100 90 80 70 60 50 40 30 5 10 15 20 25 Time [s] Speed reversal in encoderless control at low speed, while maintaining stable torque. Get started faster Automatic Motor Adaptation (AMA) at standstill reduces drive commissioning complexity and time in demanding applications, for both encoder-based and encoderless 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. Automated commissioning sequence For easy commissioning, the automated commissioning sequence identifies the motor type and optimizes it. The sequence consists of three automated steps: 1. First the drive detects motor type at standstill (induction motor, PM motor, or other) 2. Then the drive measures the electrical parameters of the motor at standstill (AMA function). 3. If required, the drive can then also measure the inertia of the motor load using speed controller auto- tuning.
