3.6.3 IO Control and Readouts
Depending on the hardware configuration of the drive, digital and analog inputs, digital and analog outputs, and relay outputs are
available. The I/Os can be configured and used to control the application from the drive.
All I/Os can be used as remote I/O nodes, as they are all addressed by the fieldbus of the drive.
3.6.4 Motor Control Features
3.6.4.1 Motor Control Features Overview
The motor control covers a wide range of applications, control from the most basic applications to applications requiring high-
performance motor control.
3.6.4.2 Motor Types
The drive supports standard available motors like:
l Induction motors
l Permanent magnet motors
3.6.4.3 Load Characterstics
Different load characteristics are supported to match the actual application needs:
l Variable torque: Typical load characteristic of fans and centrifugal pumps, where the load is proportional to the square of the speed.
l Constant torque: Load characteristic used in machinery where torque is needed across the full speed range. Typical application
examples are conveyors, extruders, decanters, compressors, and winches.
3.6.4.4 Motor Control Principle
Different control principles can be selected to control the motor, matching the application needs:
l U/f control for special control
l VVC+ control for the general-purpose application needs
3.6.4.5 Motor Nameplate and Catalog
Typical motor data for the actual drive are preset from factory, allowing operation of most motors. During commissioning, actual motor
data are entered in the settings of the drive, optimizing the motor control.
3.6.4.6 Automatic Motor Adaptation (AMA)
Automatic Motor Adaptation (AMA) provides optimization of motor parameters for improved shaft performance. Based on motor
nameplate data and measurements of the motor at standstill, key motor parameters are being recalculated and used to fine tune the
motor control algorithm.
3.6.4.7 Automation Energy Optimization (AEO)
The Automatic Energy Optimizer (AEO) feature optimizes the control with focus on lowering energy consumption at the actual load
point.
3.6.5 Braking of Load
3.6.5.1 Braking of Load Overview
When braking the motor controlled by the drive, various functions can be used. The specific function is selected based on the application
and the needs for how fast it should be stopped.
