5.5.4 Signal flow

[5-15] Signal flow - sensorless vector control

Internal variables of the motor control (oscilloscope signals)

• The red numbers in brackets listed in the signal flow stand for internal variables of the motor

control, which you can record by means of the Oscilloscope

for purposes of diagnostics and

documentation.
