47.31 Control value W
Modulation level of the IGBTs in Phase W. A value of 0 or 1 means full modulation.
47.32 Iu actual value
Measured value of the phase current.
47.33 Iv Actual Value
Measured value of the phase current.
47.34 Iw Actual Value
Value of the phase current calculated from the condition "Sum of all currents is equal to
0".
47.40 PWM MSVM threshold
The limiting value for modified modulation can be set in this parameter. The standard val-
ue is 100%, i.e. no modified modulation.
MSVM stands for "Modified Space Vector Modulation" and is used to improve the voltage
efficiency. However this results in increased current ripple.
47.41 Ualpha after PWM
Alpha voltage after calculating the modulation levels.
47.42 Ubeta after PWM
Beta voltage after calculating the modulation levels.
47.43 Uq after PWM
q-voltage after calculating the modulation levels.
