Figure 9-12 Determining the commutation angle offset by measuring the EMF and the standardized electrical rotor position via a DAC, with a positive motor direction of rotation
Definition of channels (Ch1 to Ch4):
Ch1: EMF phase U to neutral point
Ch2: EMF phase V to neutral point
Ch3: EMF phase W to neutral point
Ch4: Standardized electrical rotor position via DAC measuring signal
Note
If you select the measuring signal "Standardized, electrical rotor position", the SHIFT factor must be set to 8 and the offset value to – 2.5 V.
When the drive is synchronized, the difference between the EMF phase U and the electrical rotor position must not exceed 10°.
If the difference is greater than this value, the position of the zero mark must be shifted using software via MD 1016 "COMMUTATION_ANGLE_OFFSET".
