... Possibilities of motor control Reliability. FG SIGNAL The FG signal is generated in the TDF5140A by using the zero-crossing of the motor EMF from the three motor windings. Every zero-crossing in a (star connected) motor winding is used to toggle the FG output signal. The FG frequency is therefore half the commutation frequency. ...
