Chapter 5 FREQUENCY CONTROL WITH PULSE RATE INPUT
The pulse rate input feature supplies a frequency command to the inverter in pulse trains. Two pulse
input modes are available--B phase pulse (with signs) and forward/reverse rotation pulse trains.
The frequency control with pulse rate input can be enabled concurrently with the speed and
positioning controls with PG.

Name Descriptions
PI Power input terminal Receives power for the PG from an external source.
PO Power output terminal Outputs power to the PG.
CM Common terminal Common terminal for the PG power.
XA
Command input terminal
for A phase pulse train
Receives an A phase feedback pulse train.
