1.3.4 Setting up the power supply for the PG or pulse train generator
The external power supply should match the PG power voltage or pulse train generator
voltage.
Otherwise, a failure might result.
When using an internal power supply
Connect the power supply wire to the terminal [PO] on the PG interface card.
When using an external power supply
Connect the power supply wire to the terminal [PI] on the PG interface card.
1.3.5 Connecting to option terminals
Table 1.4 lists terminal symbols, names and functions of the option terminals on the PG interface
card.

XA A phase pulse input X

XZ Z phase pulse input X
Pulse input terminal for commands
To supply speed commands from the pulse train
generator or PG, connect an open-collector output
signal or complementary output signal to these
terminals.
Since [XZ] is not used for train input control,
connection to [XZ] is not required if there is no
corresponding output at the PG. In positioning
control, however, connection to [XZ] enables
positioning correction.
YA A phase pulse input Y
YB B phase pulse input Y
PG/ Pulse input
YZ Z phase pulse input Y
Pulse input terminal for feedback
These terminals are for the detection of the
inverter-driven motor speed. Connect an
open-collector output signal or complementary
output signal to these terminals
Since [YZ] is not used for speed control, connection
to [YZ] is not required if there is no corresponding
output at the PG. In positioning control, however,
connection to [YZ] enables positioning correction.
Note: Incorrect wiring of A/B phase could fail to run the motor normally or cause an inverter trip.
