ABB ACS880 N5700 Series - Operating modes of the drive

Operating modes of the drive
The drive can operate in several operating modes with different types of reference.
The mode is selectable for each control location (Local, EXT1 and EXT2) in parameter
group 19.
The following is a general representation of the reference types and control chains.
For detailed diagrams, see chapter Control chain diagrams.

Speed control mode
The motor follows a speed reference given to the drive. This mode can be used
either with estimated speed as feedback, or with an encoder or resolver for better
speed control accuracy.
Speed control mode is available in both local and external control. It is also available
both in DTC (Direct Torque Control) and scalar motor control modes.
