Settings for three-shunt configuration and FOC control
PMAC motors driven with field oriented control techniques need proper hardware
configuration of the three-phase inverter power stage. In particular, currents flowing in the
motor phases must be read through shunt resistors and their values must be amplified for
control unit processing. Generally, the current conditioning network has a different topology
than the one used in scalar control.
Sensored and sensorless techniques for motor speed reading can also be used in FOC
control.
Table 19 shows the jumper settings according to the three-shunt current reading
configuration.
