*For two−phase pulse input from PG, input 90° lead pulse to A−pulse side and 90° delay pulse to
B−pulse side during forward run.
PG signal output
The PG signal output (phases A and B) may vary according to installation loca-
tion on the motor. Refer to Fig. 4 for correct wiring.
In general, motor forward direction is counterclockwise (CCW) as viewed from
the load shaft. For YASKAWA’s motor, phase A of PG output leads phase B by
a phase angle of 90_ in clockwise (CW) rotation. According to PG, phase A lags
phase B by a phase angle of 90_ in clockwise (CW) rotation. In this case, when
PG is installed at the opposite drive end, connect phases A and B output from
PG to the option card as it is.
