6.2.6.1 Optional equipment check
You can check on the keypad whether the PG interface expansion card is set to SD, LD, PR, or PD.
From the Operating Mode screen, go to the Program Menu screen
and select "4. I/O check." Use the

The figure to the right illustrates the screen that would be
displayed when two PG interface expansion cards are installed and
set to PG (PD) and PG (SD).
6.2.6.2 I/O check
You can check the PG interface expansion card's digital input status on the inverter's keypad.
From the Operating Mode screen, go to the Program Menu screen and select "4. I/O check." Use the
and

For more information, see the section on keypad operation.
6.2.7 Protective functionality
When the inverter's protective functionality operates, the inverter immediately displays an alarm, displays
the alarm name on the keypad's LED, and allows the motor to free-run. When this functionality operates,
resume operation after clearing the cause of the malfunction. Avoid automatically resetting the alarm, for
example with an external sequence. Table 6.2.17 lists alarms related to the PG interface expansion card.
For more information about other alarms, see "Protective Operation" in the inverter's operating manual.

d0 Operation
This position deviation overrun error occurs when the load causes the motor startup to
lag relative to the pulse train command, creating a position deviation that exceeds a
previously set value. The threshold is set with function code o18 (deviation overrun
width).
p9 Operation
A broken wire was detected due to an interruption in a PG signal when line driver
operation (OPC-VG1-PG) was selected while using the SD setting.
