 Monitoring I/O terminals on the operation panel (FR-DU08) (Pr.52,
Pr.774 to Pr.776, Pr.992)
• When Pr.52 (Pr.774 to Pr.776, Pr.992) = "55", the I/O terminal state can be monitored on the operation panel (FR-DU08).
• When a terminal is ON, the corresponding LED segment is ON. The center LED segments are always ON.

• On the I/O terminal monitor, the upper LEDs indicate the input terminal status, and the lower LEDs indicate the output terminal
status.

Main circuit capacitor life measuring
The measurement of the main circuit capacitor life can start whenever the power supply is turned OFF without setting
the parameter every time.

 Life display of the main circuit capacitor (Pr.258, Pr.259) (Standard
models and IP55 compatible models)
• For accurate life measurement of the main circuit capacitor, wait three hours or longer after turning OFF. The
temperature left in the main circuit capacitor affects measurement.

Setting "1" and turning the power supply OFF starts the
measurement of the main circuit capacitor life. (Only once)

supply ON again, it means that the measurement is completed. The
deterioration degree is read to Pr.258.
When "11" is set, turning OFF the power supply starts the
measurement of the main circuit capacitor life.
