General Instructions
English
“Optimal Braking” function for the vector control, allowing the controlled braking of the motor
and avoiding external braking resistor for some applications.
“Self-Tuning” feature for vector control. It allows the automatic adjustment of the regulators
and control parameters from the identification (also automatic) of the motor parameters and
load.
The main components of the CFW700 can be viewed in Figure A.1 on page 207.
